煩人的智齒 - 為什么人類進化沒有淘汰掉它？
Why Do We (Still) Have Wisdom Teeth?
譯文簡介
你有拔過智齒嗎？如果有，那你有沒有想過，為什么智齒這種東西在人類進化的過程中沒有被淘汰？接下來我們就以人類智齒為切入點，探討其生物學(xué)特征、普遍存在問題及其進化起源。
正文翻譯
人類口腔中的第三磨牙因其生長階段晚、空間適應(yīng)性差且常伴隨病理問題，在醫(yī)學(xué)領(lǐng)域被稱為智齒。這種特殊的牙齒結(jié)構(gòu)普遍存在于現(xiàn)代人類口腔中，卻因其頻繁引發(fā)阻生、齲齒及鄰牙損傷等問題，成為臨床牙科最常見的拔除對象。從生物學(xué)視角觀察，智齒的生長規(guī)律具有顯著特殊性：其萌發(fā)時間通常延遲至個體發(fā)育成熟階段，約在18至25歲間開始突破牙齦，此時人類頜骨發(fā)育已基本定型。統(tǒng)計數(shù)據(jù)表明，超過半數(shù)人口至少存在一顆阻生智齒，而98%的阻生病例源自第三磨牙，這種高發(fā)率與人類頜骨空間的進化性縮減存在直接關(guān)聯(lián)。
進化生物學(xué)研究揭示，智齒作為靈長類動物共有的牙齒結(jié)構(gòu)，在人類早期祖先中曾發(fā)揮重要咀嚼功能。黑猩猩、大猩猩等現(xiàn)存類人猿仍保持較寬闊的頜骨結(jié)構(gòu)，其第三磨牙能正常萌發(fā)并參與食物研磨。但人類自直立人階段開始，隨著腦容量擴大與顱骨結(jié)構(gòu)改變，頜骨逐漸縮短變窄。這種形態(tài)學(xué)變化與人類飲食結(jié)構(gòu)的轉(zhuǎn)變形成協(xié)同進化關(guān)系：烹飪技術(shù)的出現(xiàn)使食物趨向軟化，降低了對強力咀嚼器官的依賴，頜骨肌肉附著區(qū)域隨之縮小。在此過程中，第三磨牙的生理空間被持續(xù)壓縮，最終導(dǎo)致現(xiàn)代人類普遍面臨智齒萌發(fā)空間不足的困境。
現(xiàn)代人類中約20%個體存在先天缺失部分或全部智齒的現(xiàn)象，這種遺傳變異提示該器官正處于進化消退階段。從進化痕跡理論分析，智齒已從功能性器官轉(zhuǎn)變?yōu)楹圹E器官，其存在僅反映物種進化歷程而非現(xiàn)實生理需求。這種器官退化現(xiàn)象與闌尾的進化軌跡具有相似性，均表現(xiàn)為原始功能的喪失與解剖結(jié)構(gòu)的殘留。臨床醫(yī)學(xué)實踐顯示，智齒阻生不僅造成局部炎癥與疼痛，更可能引發(fā)牙列擁擠、鄰牙根吸收等復(fù)雜病癥，這促使預(yù)防性拔除成為現(xiàn)代牙科的常規(guī)處置方案。
從生物力學(xué)角度觀察，智齒萌發(fā)時的機械壓力可能打破原有牙列平衡，這種生物學(xué)特性與人類頜骨容積縮減形成矛盾關(guān)系。比較解剖學(xué)研究證實，尼安德特人等古人類已顯現(xiàn)出頜骨縮小的趨勢，但其程度遠不及現(xiàn)代人類。這種加速進化現(xiàn)象或與近萬年來農(nóng)業(yè)文明帶來的飲食精細化密切相關(guān)。智齒問題因此成為人類進化過程中形態(tài)適應(yīng)與文化變革相互作用的具體例證，既體現(xiàn)生物器官對環(huán)境變遷的滯后性適應(yīng)，也折射出文明發(fā)展對生物體結(jié)構(gòu)的深層影響。

Got mine ripped out in Recruit Training. Inadequate anesthesia, only a day to recover, and digging food out of the poorly-stitched holes with the back of a safety pin in the middle of the night made it a very uncomfortable experience.
Word of advice: if anyone is planning on joining the military, get your wisdom teeth out beforehand.
我的智齒是在新兵訓(xùn)練時被強行拔掉的，麻醉效果差，只給了一天恢復(fù)時間，半夜還得用安全別針的背面從縫線粗糙的牙洞里摳食物殘渣，整個過程非常折磨人。在此奉勸一句：如果有人打算參軍，入伍前先把智齒拔了吧。
I am 63 and still have all four of my wisdom teeth. I have had many hygienists and dentists comment that they are tiny and "cute".
我今年63歲，四顆智齒都還在。好多牙醫(yī)和潔牙師都評價說它們又小又“可愛”。
Navy yanked all 4 of mine at once. Got 1 day to recover, then I had to go back to work looking all pitiful
海軍一次性拔掉我全部四顆智齒，只給了一天恢復(fù)時間，然后就讓我可憐巴巴地回去上班了。
I was in my late 20s and wondering why my wisdom teeth hadn’t come through yet. One day I went to dentist for a back tooth to be taken out and the dentist took an x-ray of my mouth and was like "this won’t hurt as much as when you got your wisdom teeth out" and when I said I’d never had them out he was confused and said I don’t have any in the x-ray.
Turns out I was just born without wisdom teeth. Always just assumed everyone had them.
快30歲時，我還在納悶智齒怎么還沒長出來。某天我去拔后槽牙，牙醫(yī)拍了X光片后說“這可比你拔智齒輕松多了”，結(jié)果我告訴他從沒拔過智齒，他一臉困惑地指著片子說：“你壓根沒長智齒啊?！苯Y(jié)果發(fā)現(xiàn)我天生就沒有智齒，之前一直以為所有人都有呢。
One of my molars fell out and my wisdom tooth finally has the chance to actually do its job. And even then, it requires years of help to actually move into the right spot. And my other wisdom teeth are literally horizontal. It is impressive how bad they are at being useful teeth.
我的一顆臼齒掉了，智齒終于有機會發(fā)揮作用，但即便如此，它還需要好幾年輔助才能移到正確位置。另外幾顆智齒干脆是橫著長的，真是佩服它們“長殘了”的本事。

The Marine Corps decided to take mine out preemptively. Got the afternoon off. PT the next morning was a 3 mile battalion run. 40 years later, I can still feel the hollow dull thud every time my feet hit the ground.
海軍陸戰(zhàn)隊決定先下手為強拔了我的智齒，當天下午放了假。結(jié)果第二天一早的體能訓(xùn)練是全營三英里跑。四十年過去了，每次跑步腳掌落地時，我還能感受到那種空洞的鈍痛。
too few of us 'moderns' die from wisdom teeth complications for there to be a evolutionary sextion pressure. So we are stuck with them.
我們“現(xiàn)代人”很少因智齒并發(fā)癥死亡，自然選擇的壓力不夠，所以只能繼續(xù)和它們共存了。
I’ve always been SOOOOO grateful to have ALL FOUR of my WT grow at the same time (around age 19-20) but straight up instead of causing a mess :D I was so scared to have to remove them. But they just popped up and didn’t trigger any issue. Whew !!
我特別慶幸自己四顆智齒在19-20歲時同時長齊，而且筆直沒添亂！之前超怕要拔牙，結(jié)果它們乖乖冒頭，一點麻煩都沒惹，真是謝天謝地！
i must be a throwback. I have all my wisdom teeth, and they came in nicely with no issues. I’m tall and have a larger jaw which probably makes sense. I have Norwegian ancestors as well. I’ve always wondered about the genetics of wisdom teeth. Both of my children had 2 removed.
我可能是個返祖案例——四顆智齒都長得整整齊齊沒出問題。我個子高、下顎寬大，祖上還有挪威血統(tǒng)，大概基因起了作用。不過我一直好奇智齒遺傳規(guī)律，畢竟我的兩個孩子都拔了兩顆。
Mine all finally burst through my gums in my late 30’s. They shoved my other teeth forward enough that the root of one of my other molars started impinging on a major facial nerve and giving me a permanent migraine. When we eventually figured this out and had them all removed. Instant relief! I’m the only person I know who had less pain after oral surgery.
我的智齒直到快40歲才全部冒頭，結(jié)果把其他牙齒頂?shù)角耙?，?dǎo)致一顆臼齒的牙根壓迫面部神經(jīng)，害我得了長期偏頭痛。最后發(fā)現(xiàn)問題根源并拔掉智齒后，瞬間解脫！我大概是唯一一個覺得拔牙后反而更輕松的人。
I never grew any and can always find time to sit on the couch and eat ice cream. No excuses needed.
我根本沒長智齒，所以隨時能癱在沙發(fā)上吃冰淇淋，連借口都不用找。
As one of the very few people who has had miraculously zero problems with my wisdom teeth growing out, I STILL have issues with them on a frequent basis anyway, like when I wanna extend my jaw to the sides and they end up grinding upon the very back of it.
雖然我屬于智齒生長全程零問題的幸運兒，但日常還是會被折騰——比如側(cè)張下巴時，智齒總會磨到口腔最深處。
Before dentistry, humans probably already have significant tooth decay by 25yo. I imagine the back teeth have the most decay since they are the hardest to clean. Thus, we may have an extra back set of teeth that come in later when our primary rear molars ultimately begin rotting out. One man’s hypothesis...
在沒有牙科醫(yī)學(xué)的年代，人類可能25歲就滿口爛牙了。后槽牙最難清潔，估計最早蛀光，所以進化出智齒作為替補，等原裝后槽牙爛完再上崗——以上純屬個人假說。
I’m happy mine grew in fine and I’ve never had any problem, but my little brother on the other...
我的智齒長得挺好從沒出問題，但我弟弟就...
I had a 1 hour drive home in rural 100F Alabama while I threw up blood into a plastic bag. That was fun.
我曾一邊在阿拉巴馬州鄉(xiāng)下100華氏度的天氣里開車一小時回家，一邊往塑料袋里吐血，真是段“美好”回憶。

my daughter had ZERO wisdom teeth, per her dentist. i have an impacted one and i’m so glad she won’t have to deal with that.
我女兒壓根沒長智齒（牙醫(yī)確認過）。我自己有顆阻生智齒，超慶幸她不用遭這罪。
I’m over 40 and have never had my wisdom teeth. None, not even extracted. My mouth is already tiny for different reasons, so I’m glad to know I have another small bonus in not having had my wisdom teeth.
我40多歲了，從沒長過智齒，也沒拔過。本來就因其他原因口腔空間小，所以很慶幸少了這個負擔。
My jaw was so small that I didn’t have room for all my regular molars. I had to have 2 removed on the bottom, and my upper jaw was expanded to make room for them (one is still sticking out to the side). When my wisdom teeth started coming in, it was a given that all 4 had to come out.
我下顎太小，連正常臼齒都排不下，不得不拔掉兩顆下牙，上顎還被擴開騰位置（至今有顆牙歪在一邊）。所以智齒一冒頭，四顆全拔毫無懸念。
My teeth were screwed up from a young age. I had a giant tooth gap on both my top and bottom row - probably should have had braces, but we didn’t have the money for them. So when my wisdom teeth finally came in and pushed both rows of my teeth together, I felt like I won the lottery
我從小牙列不齊，上下排都有大牙縫——本該戴牙套矯正，但家里沒錢。結(jié)果智齒長出來后把兩排牙擠攏了，簡直像中了彩票！
I had a friend who never had a single cavity and had all his wisdom teeth til the day he died. I on the other hand had cavities from early in life, never had a tooth that came in in-line, had braces in high school, and had all 4 wisdom teeth surgically removed in my 20’s. At almost 60, I have almost no teeth left.
我有個朋友一輩子沒蛀牙，智齒保留到去世。而我從小就蛀牙，牙齒沒一顆整齊，高中戴牙套，20多歲動手術(shù)拔四顆智齒?，F(xiàn)在快60歲，牙都快掉光了。
Mine came out at 16. I came out at 17... Cue Rogers and Hammerstein.
我16歲拔了智齒，17歲出柜... 請自行腦補《音樂之聲》BGM。
Thankfully I had the second best wisdom teeth outcome: All 4 properly aligned, no issues. Best outcome? No having any.
謝天謝地，我的智齒結(jié)局算第二好：四顆整齊無礙。最好的結(jié)局？當然是壓根不長！
I’m one of the lucky few that had their wisdom teeth grow in with no issues. It was a big surprise when I moved and got a new dentist.
我是少數(shù)智齒順利生長無阻的幸運兒。后來搬家換牙醫(yī)，對方看到片子時超驚訝。
When I was 19, my wisdom teeth literally tried to kill me, contributing to permanent nerve damage in my maxillofacial musculature and leaving massive gaps in my skull and jaw after their removal. The pain prior to their removal was causing me to have severe migraines and blackouts.
19歲時，我的智齒差點要了我的命——導(dǎo)致頜面部肌肉永久性神經(jīng)損傷，拔除后顱骨和下頜還留下大空洞。拔牙前的劇痛讓我頻繁偏頭痛甚至昏厥。
All four of mine came in straight and clean (big jaw, small teeth, plenty of room). Dentist wisely decided not to mess with them. Actually kinda nice having the extra crushers in the back.
我四顆智齒都筆直干凈（下顎寬、牙小、空間足），牙醫(yī)明智地決定不碰它們。多幾顆后槽牙碾碎食物其實挺爽。
My brother and I(twins) both no issues with ours. Guess we were fortunate.
我和雙胞胎兄弟的智齒都沒出過問題，算走運了。

All my wisdom teeth came in good, just need to work on keeping them and my gums healthy :D
我智齒長得挺好，現(xiàn)在只需努力保持牙齒和牙齦健康就行啦
I literally just got mine removed on Monday
我周一剛拔完智齒。
I got mine removed. Years of fear of the pain to have all 4(impacted like they are fully horizontal) removed just for the dentist to do an amazing job and have zero pain even for the first couple of hours after anesthesia wore off. Barely used pain killers. I’m happy bc mine got so bad to the point they made pockets next to them that food got really stuck.
終于拔了四顆全水平阻生的智齒。怕疼怕了好幾年，結(jié)果牙醫(yī)技術(shù)超神，連麻醉失效后都沒怎么痛，止痛藥都沒咋吃。之前智齒爛到旁邊形成凹洞總卡食物，現(xiàn)在解脫了！
Lots of horror stories here. I’ll add mine to the mix. I broke a wisdom tooth on a stealthy chicken bone. For a while, it didn’t cause any problems but eventually I decided discretion was the better part of valour and went to the dentist. An X-ray showed that two were impacted already. So an appointment with a specialist later... The specialist pulled out those teeth very quickly - almost frighteningly so. After returning home, I was in a good deal of pain but there was little to be done. I was supposed to recover over the weekend but a nasal infection set in. I was off sick from work for a full week. Still, it removed a lot of fear of dentistry in me that many of my generation have. Routine work is nothing compared to the trouble those wisdom teeth caused.
我也貢獻個恐怖故事：有次啃雞骨頭時暗戳戳硌裂了智齒。起初沒事，后來還是慫了去看牙醫(yī)，結(jié)果X光顯示兩顆已阻生。約專家拔牙時，對方手法快得嚇人?；丶液髣⊥措y忍，本想周末養(yǎng)傷，卻并發(fā)鼻竇炎，最后請了一周病假。不過經(jīng)此一役，倒治好了我們這代人對牙醫(yī)的恐懼——畢竟常規(guī)治療可比智齒作妖輕松多了。
There are people (a lot in Asia) that have even smaller jaws, to the point they don’t even have enough space for the "basic" teeth. That’s why having crooked teeth in Japan is common, and the only way to fix it is to get rid of the four small ones on the sides of the front ones, and then arrange the rest with the now enough space using braces. But at least most of them don’t get the Wisdom teeth anymore, otherwise the room gets even more packed and teeth have no where else to go than in between and behind/ahead of others (impacted).
很多亞洲人下顎更小，連正常牙都排不下，所以日本普遍牙列不齊，解決辦法通常是拔掉前牙兩側(cè)四顆小牙，再用牙套調(diào)整剩余牙齒。好在多數(shù)人不長智齒，否則口腔更擁擠，牙齒只能亂擠成阻生狀態(tài)。
I only had one wisdom tooth come in at all, and when it was time to take it out the dentist realized it was loose enough he could just reach in there and pull it out with his fingers. My recovery time was extremely fast.
我只長了一顆智齒，到要拔的時候，牙醫(yī)發(fā)現(xiàn)它已經(jīng)松到可以直接用手指拔出來，所以恢復(fù)期特別快。
I was lucky enough to be born without any of the 4 wisdom teeth.
我運氣很好，天生就沒有四顆智齒。
Only three out of four grew out for me, and none gave me any problems.
我的四顆智齒只長出了三顆，而且都沒出過問題。
I didn't have wisdom teeth, but sitting on the couch eating ice cream for a week makes me wish I did!
雖然我沒長過智齒，但看到別人能借口躺沙發(fā)吃一星期冰淇淋，我都忍不住羨慕了！
Mine came through in my early 40s. One was able to be removed in the chair, where the other 3 were severely impacted and had to be removed under general anesthesia. Apparently the operation was harder took longer. Ended up with 2 weeks off work, with the first week mainly eating cold soft foods like icecream, yogurt, moose, erc.
我的智齒40歲出頭才長出來。其中一顆能直接拔，剩下三顆嚴重阻生必須全麻手術(shù)。據(jù)說手術(shù)難度高又費時，最后我請了兩周假，第一周基本靠冰淇淋、酸奶和慕斯這類冷軟食度日。
I got two of my wisdom teeth removed and it was a hell. The dentist had to apply a lot of anesthesia, and three weeks after the procedure, my lips are still numb. The pain was so intense that I literally cried for days. And the fact that I'm diabetic made it worse, because the healing process is more complicated.
我拔了兩顆智齒，過程簡直是地獄。牙醫(yī)打了超多麻醉，但術(shù)后三周嘴唇還發(fā)麻。痛到我連哭好幾天，再加上本身有糖尿病，傷口愈合更麻煩。
I had all 4 wisdom teeth grow in straight. Even have a little space behind the wisdom teeth.
我四顆智齒都長得筆直，后面甚至還有空隙。
I only ever had one wisdom tooth, and even that one, though it did come in impacted, dissolved completely on its own before the dentist could pull it. My dentist said on my x-ray they couldn't even see any roots, for the one wisdom tooth I got then lost or where the other three would have been.
我只長過一顆智齒，雖然阻生，但還沒等拔就自己溶解消失了。牙醫(yī)說X光片上看不到牙根，連原本該長其他三顆智齒的位置也空蕩蕩的。
I’m in my 40s and recently had a tiny little wisdom tooth irrupt even though I had my wisdom teeth removed in my 20s. It’s the size of a baby tooth and my dentist were so enamored.
我40多歲居然又冒了顆迷你智齒，明明20多歲就全拔過了。這顆牙只有乳牙大小，牙醫(yī)們看得嘖嘖稱奇。
My wisdom teeth are like: "Why are we here...just to suffer?"
Tried to get them removed, but got told that I might need them when I'm older to bridge other teeth that may fall.
I can't stand them, I'm always biting my cheek inevitably when I eat something I really enjoy, they make me bleed.
我的智齒仿佛在說："我們來這世界就是為了受苦嗎？"
想拔掉卻被勸告說年紀大了可能需要它們當備用牙，現(xiàn)在每次吃美食必咬到臉頰出血，實在受不了。

I have all my wisdom teeth left, the upper once are a bit slanted but anyhow a dentist got surprised i still had all left.
我四顆智齒都還在，上排有點歪，但牙醫(yī)看到時還是很驚訝。
only just started the video but, i was born with bad molars, they had to be pulled when i was 10 years old and the wisdom took the place of the bad molars and since then i had no teeth problems
視頻剛開始看，但我天生臼齒不好，10歲就拔了，結(jié)果智齒頂替了位置，之后再沒出過問題。
I had all 4 impacted and needed surgery. I was able to handle the pain of both surgery and recovery. The one thing that still made me uncomfortable was the smell of the drill cutting into my wisdom tooth.
四顆智齒都阻生需要手術(shù)。我能忍痛，但電鉆磨牙的氣味至今想起都反胃。
I had all four come up fine but the dentist removed them for some reason. Years later I grew one mini two-point replacement I still have
智齒本來長得挺好，但不知為何被拔了。多年后竟又長出一顆迷你雙尖牙，現(xiàn)在還留著。
All 3 of mine grew in with no issues. I never had the 4th but had plenty of room for it.
三顆智齒順利長出，第四顆沒長但空間足夠。
Got all mine, and they all fit and came in correctly!
四顆智齒齊全，長得整整齊齊！
the timing of this upload is crazy because i have two wisdom teeth removal in 3 hours
這視頻上傳得太巧了——我三小時后就要去拔兩顆智齒！
I had to get mine all four removed because they never stopped growing and started hindering chewing got removed one by one as they started emerging.
四顆智齒持續(xù)生長影響咀嚼，只能分批拔除。
I don't have any Wisdom teeth and XRays have shown I never will! 24 and will thankfully never have to deal with this pain, and I am so thankful for that
X光顯示我天生沒智齒，24歲的我永遠不用受這罪，謝天謝地！
I had one of my lower ones removed just 2 days ago. I had all 4 come in just fine, but because of space constraints, the gums partially overlapped the back parts and i couldn't over time keep them clean enough and got holes, so i removed the top 2 in my early 30s and now the first of my lower ones at 37, and will probably have to remove the other lower later this year or next. The top ones came out easy, but the bottom one not as much... My dentist left the bottom of the roots inside the jaw and just flattened and polished them so they wouldn't irritate and potentially infect the gums. I'm on paracetamol, but managed to keep working the same day, yesterday and today. But I've heard of several people that had pieces of their jaw bone removed to get the roots out, and they were knocked out for a few days on the strong stuff.
兩天前剛拔左下智齒。雖然四顆都長齊了，但牙齦覆蓋導(dǎo)致蛀牙，30多歲拔了上排兩顆，現(xiàn)在37歲開始處理下排。下排比較難拔，牙醫(yī)留了點牙根在頜骨里磨平防感染。我吃撲熱息痛就能上班，但聽說有人被削骨取根，得躺好幾天。
I was lucky to only have the two top wisdom teeth and they weren't causing any pain. However, I still decided to have them removed since it was free. I asked if I got numbed, instead of being knocked out, if I'd be able to drive myself home and I could. It was one of the strangest feelings to be able to hear the saw and feel my whole head being pulled down, but not being able to feel anything inside my mouth. No pain or the texture of the gloves and tools being used. There was a good week where I had to be careful of how I ate, but that didn't change what I ate. I still enjoyed my favorite food, I just had to eat slower and smaller bites to avoid damaging the wounded area of my mouth or cause infection.
只有上排兩顆智齒且不痛，但免費就拔了。局麻后自己開車回家，聽著電鋸聲感覺腦袋被拉扯，嘴里卻毫無知覺?；謴?fù)期照樣吃香喝辣，只是得小口慢咽。
When my wisdom teeth started coming out I purposly grinded my teeth to rip up my gums to stop the swelling, now they just hang semi out and one of my mollars is rotated.
智齒萌出時我故意磨牙撕開牙齦消腫，現(xiàn)在它們半露不露，還帶歪了一顆臼齒。
In Dutch we call them "verstandskiezen". That can be translated literally into English as wisdom teeth (verstand = wisdom, kiezen = teeth although the word specifically refers to the molars), but you can also use a different emphasis and pronounce it "VERstandskiezen", in which case it would refer to molars in the back of the mouth, which is also correct. Since I'm missing 3 out of 4 of them and the 4th one has never emerged from my jaw, I make it a point to use the second pronunciation.
荷蘭語叫"verstandskiezen"，字面是"智慧牙"，但重音放前面就指"后槽牙"。我缺了三顆智齒，第四顆也沒長，所以堅持用第二種發(fā)音。
I got mine out... I was fine the same day, took the next day off not because I had to... just... why not!
It's a day off and was expected! I'll take it!
拔完智齒當天就活蹦亂跳，第二天純粹找借口休假——有便宜不占王八蛋！
I have them all and still have a bit of space left
四顆智齒齊全，牙床還有空位。
Im still dealing with the tooth decay caused by my wisdom teeth... my 2nd molar on my top right side had to be removed entirely as well

My X-rays always showed I didn’t have wisdom teeth or twelve year molars…until I was 25! A single wisdom tooth mysteriously showed up way late in life. It took another 5 years to break through the gums. I’m 43, and it’s still in my mouth, not causing problems.
X光一直顯示沒智齒，結(jié)果25歲突然冒出一顆，又花了五年才破齦?，F(xiàn)在43歲，這顆遲到智齒乖乖待在嘴里不惹事。
I never developed any wisdom teeth. So I never had to deal with their problems. I remember my dentist saying that it was unusual to have someone without even one develop!
從沒長過智齒，牙醫(yī)都說這種情況很少見。
I still have my wisdom teeth.
I lost one top and one bottom molar early (injury) and we just adjusted the whole set to let the wisdom teeth take their places over a year.
Handy to have spares!
還留著智齒。早年受傷失去上下各一顆臼齒，花一年調(diào)整讓智齒頂替，自帶備用牙真方便！
Glad to know it's not totally uncommon to be missing wisdom teeth. I had braces when I was younger and was worried my wisdom teeth would mess up all that work. Turned out, each of my parents were missing two and I never developed any. My brother wasn't so lucky, he had all four.
很高興得知并非只有我天生缺少智齒。我年輕時戴過牙套，當時總擔心智齒會毀掉矯正成果。結(jié)果發(fā)現(xiàn)我父母各自缺失兩顆智齒，而我則完全沒長過。我弟弟就沒這么幸運了，他四顆全長齊了。
I had two or three of my wisdom teeth (I legitimately don't remember which), and as they started growing in, they began irritating the sides of my mouth. That caused inflammation, which blocked my parotid duct (salivary tube). Caused a ton of jaw and even neck pain on and off for several months before the doctor said, "time to get those things removed". I hate needles, so I asked if there was a way they could do the extraction without the Novocaine shot; they said no, but they gave me nitrous oxide before the shot, and man... that's the only time I've had N2O, but I love it I wasn't giggling like the movies always show, I just was kind of... calm. Like I was living in a dream a bit, where nothing bothered me. As they worked on my mouth, I could feel everything, and I knew it should hurt -- especially that initial needle -- but I just... didn't care about it
TL;DR: I had my wisdom teeth removed and learned that N2O is a miracle drug in the same day
我有兩到三顆智齒（真心記不清具體數(shù)量），當它們開始生長時不斷摩擦口腔內(nèi)壁，導(dǎo)致炎癥并堵塞腮腺導(dǎo)管。這讓我下頜甚至頸部反復(fù)劇痛了好幾個月，直到醫(yī)生宣布"必須拔掉"。我討厭打針，于是詢問能否不用麻醉直接拔牙，結(jié)果被拒絕。不過他們在注射前給我用了笑氣——天啊，雖然這是我唯一一次體驗一氧化二氮，但徹底愛上它了！我并沒有像電影里演的那樣傻笑，反而異常平靜，仿佛活在夢境里。雖然能清晰感受到所有操作（尤其是最初的針頭），但就是完全不在乎疼痛。
簡單來說：拔智齒當天，我發(fā)現(xiàn)了笑氣的神奇魔力。
Don’t ignore your dentist when they say they need to come out! Was told to get them out at 20, got them out at 29 and the headaches from teeth not having room are not joke
千萬別無視牙醫(yī)的拔牙建議！我20歲就該拔智齒，結(jié)果拖到29歲。牙齒擁擠導(dǎo)致的頭痛真不是開玩笑的。
I'm in my 50s and I'm still not 'wise' - never had my wisdom teeth emerge - got 2 gummy spaces at the back of my top teeth. I remember when my older sister had hers out - mine, just never did anything.
五十多歲的我依然不夠"智慧"——智齒從未萌出，上排牙后方留有兩處凹陷。記得姐姐當年拔過智齒，而我的壓根沒動靜。
I only ever got 1 wisdom tooth, but I wasn't expected to have any. My teenager was also expected to not get any, but ended up getting two, which needed to be pulled.
我只長過1顆智齒，而原本預(yù)測我不會有任何智齒。我孩子也被認為不會長，結(jié)果冒出兩顆需要拔除的。
I had one of my second molars extracted as a kid and later my orthodontist moved the wisdom tooth in it's place
童年時拔了第二磨牙，后來正畸醫(yī)生將智齒牽引到空缺位置。
The reason they come in late was because we used to wear teeth down. Especially the molars, so a worn down molar would just give way for the last one and fall out. Today we keep our teeth but nature hasn't caught up with that fact yet.
Fun fact: most people get their wisdom teeth unnecessary removed, as your adult jaw need about 8 years to adapt to them. Only if a wisdom tooth is loose or there is an infection underneath it should it be pulled. And if that is the case you heal up quick. The fact that you spend a week on the couch eating ice-cream is unfortounally the proof you tooth was taken out unnecessarily.
智齒晚萌是因為古人牙齒磨損快，磨牙磨平后自然脫落給智齒騰位?，F(xiàn)代人牙齒保養(yǎng)得當，但進化沒跟上這個變化。
冷知識：多數(shù)人無需拔智齒，成人頜骨需約8年適應(yīng)期。只有松動或引發(fā)感染的才需拔除，且恢復(fù)很快。需要臥床吃冰淇淋一周的情況，反而說明拔牙是過度治療。
It would have been interesting for you to cover the latest advances in preventing the buds of wisdom teeth from ever developing, thus avoiding the likely need for wisdom tooth extraction.
要是能講講預(yù)防智齒胚芽發(fā)育的新技術(shù)就更有趣了，這樣能徹底避免拔牙需求。
I....(Clears throat, adjusts collar and puts on a smirk) never had wisdom teeth. My dentist said I was lucky because my siblings and my mother had them.
我嘛…（清清嗓子，整整衣領(lǐng)，露出得意笑容）天生沒長智齒。牙醫(yī)說這很幸運，畢竟兄弟姐妹和母親都長過。
I had only a small remnant of one on my top left. It became impacted and, despite being the size of a pea, caused some significant pain.
左上頜曾有個豌豆大小的智齒殘根，阻生后引發(fā)劇烈疼痛。
I am one of those who wisdom teeth never came in all the way. I had a bad experience with a dentust as a late teen and stopped going. My gums over the wisdom teeth never receded so food was trapped there leading to decay. I had all four pulled at different times because they were so hard to remove my new dentist actually got tired. That was in 1998 when I was 31. 57 now and still go to the same dentist.
我的智齒從未完全萌出。青少年時期遭遇糟糕牙醫(yī)后拒絕就診，牙齦長期覆蓋智齒導(dǎo)致食物嵌塞腐爛。四顆分次拔除時異常困難，新牙醫(yī)都拔到體力不支。1998年31歲時完成，現(xiàn)年57歲仍找同一位牙醫(yī)。

I have a tooth missing (just never grew) so I was kinda looking forward to a wisdom tooth on that side to even things out… to date it’s the only wisdom tooth that has grown out, and it decided to grow into my cheek muscle was brutal!
天生缺顆牙，曾期待同側(cè)智齒補位。結(jié)果唯一萌出的智齒竟長進頰肌，痛到懷疑人生。
I'm almost 48 and my dentist recommends I keep mine. I've never had an issue, never even felt them come in that I'm aware of! My brothers and my childrens all grew in impacted :(
48歲，牙醫(yī)建議保留智齒。從未感覺它們萌出，更沒出過問題。但兄弟和孩子們的智齒都阻生了。
I had mine all cut out from the inside at once in high school. My jaw didn't have room for all the normal teeth, and I had to have one of the front ones pulled. I have a tiny jaw.
高中時一次性內(nèi)切拔除所有智齒。因頜骨太小，連門牙都拔過一顆騰空間。
Probably still here because there's no reason for them to not be, at least in evolutionary terms - most people who live in societies where wisdom teeth are a common issue also live in societies with decent healthcare that can get them removed, and if no one dies, the "wisdom teeth: yes" gene(s) won't go away as quickly. Why do we have tailbones? Nobody dies faster because of their tailbone, so there's no reason for a "tailbone: no" gene to become advantageous and spread more
智齒留存于進化層面是因為：存在智齒問題的群體通常享有完善醫(yī)療，不會因此死亡，相關(guān)基因就不會快速淘汰。就像尾椎骨雖無用卻未被淘汰——沒人因它死亡，自然無進化壓力。
Yeah I was born with only 3 and I kept them for awhile and held off on removing them. They all grew like 90% out and everything was fine. But one day I got the feeling they where a little bit more sore then usual. Waited a day or two and didn't like how it was going so I made the decision I wasn't going to tempt fate and got them out in the next few weeks.
It's the only time I've had a surgery and been put out. I got lucky and didn't have any adverse effects.
I even experimented with less and less oxi they gave me as it was healing up. I always hear horror story's from people that stuff doesn't go as well.
天生3顆智齒，原本生長良好就沒拔。某天異常酸痛，觀察兩天后決定不冒險，幾周內(nèi)全部拔除。這是唯一一次全麻手術(shù)，幸運的是無副作用。恢復(fù)期還嘗試減少止痛藥用量，畢竟常聽別人說會遭遇并發(fā)癥。
i had 6! i’ve had 4 taken out because they were dangerously close to the nerve, but i still have my two extra up top
我有6顆智齒！因4顆臨近神經(jīng)而拔除，目前還剩上排兩顆額外智齒。
My dad didn't get his removed until they'd impacted his other teeth, and he was put under for a removal surgery that was like 4 hours. Meanwhile, I preemptively got mine removed before they could try to squeeze in (back in my late teens), and I had a much shorter op where I remained awake.
If they're expected to cause problems, it might be better to get them removed sooner than later.
父親拖到智齒擠壓鄰牙才拔，經(jīng)歷4小時全麻手術(shù)。我十幾歲就預(yù)防性拔除，保持清醒完成短時手術(shù)。若預(yù)判會出問題，早拔早好。

I have mine, never been an issue. Dentist has always been pleased with my care of them, too.
智齒健在，從未惹禍。牙醫(yī)也稱贊我護理得當。
One of my brothers only had a couple, while my other brother was born without any wisdom teeth. I of course had to have all four surgically removed.
我有個兄弟只長了兩顆智齒，另一個兄弟天生就沒有智齒。而我呢，最后不得不通過手術(shù)把四顆全拔了。

Had my first one pulled out in my early 20's, the two in the upper jaw they kind of dealt with themselves in time without me even knowing it. I have one remaining and it seems to be in good condition. Like another poster mentioned I had a small jaw as well but had bracers growing up so they had already pulled out 4 teeth.
我20歲出頭拔了第一顆智齒，上頜的兩顆后來不知不覺自己脫落了?，F(xiàn)在還剩一顆，狀態(tài)還挺好。和之前某位網(wǎng)友說的一樣，我下顎骨也偏小，不過小時候戴過牙套，所以已經(jīng)拔過四顆牙了。
I had one impacted (it was unerupted and completely sideways) and I got both removed on that side. I'm 43 and still have the other 2 on the other side that haven't caused any issues.
我右下頜有顆阻生智齒（完全埋在牙齦里且橫著長），最后把那一側(cè)兩顆都拔了?，F(xiàn)在43歲，左側(cè)兩顆一直沒出問題，就這么留著。
I’m glad my wisdom teeth fit just right. I actually see quite a bit of jaw left in my mouth but I definitely do have my wisdom teeth sitting comfortably back there! I did have 4 extra teeth that were essentially 4 really sharp canines
慶幸我的智齒長得剛剛好，雖然下顎空間看著還有余量，但四顆都安穩(wěn)待在后面。不過之前倒是多長過四顆尖尖的犬齒。
All four of mine were impacted, had to have them pulled surgically as they started pushing on my other teeth - took one month to fully recover
四顆全是阻生齒，因為擠壓鄰牙不得不手術(shù)拔除，結(jié)果花了一個月才徹底恢復(fù)。
I only had two. Had to have them removed about 24 years old. I ate fish tacos with a friend that night. I did whatever and just took really good care to irrigate and clean super frequently. Worked out fine for me
我就長了兩顆，24歲左右拔的。當晚居然還和朋友吃了魚肉卷餅！之后勤用沖牙器、加強清潔，恢復(fù)得倒挺順利。
Two separate operations for me, before they started to come out; bottom ones first, then a year or so later my top ones.
分了兩次手術(shù)：智齒還沒冒頭時先拔了下頜兩顆，隔了一年左右又拔了上面兩顆。
Thought I'd get away with never having any wisdom teeth, since the buds kept not showing up on x-rays. I was 24 (!) when two upper wisdoms finally developed. They came in just fine, oddly enough, but my dentist yanked them anyway, on the grounds they were so far back they'd never get properly brushed.
本來以為能逃過一劫——X光片總照不出牙胚。結(jié)果24歲突然長出上頜兩顆智齒！雖然長得端正，但牙醫(yī)堅持要拔，理由是位置太靠后根本刷不到。
I don't have any of them (as in it is never there in the first place), yet my younger sister has all 4.
我天生沒長過智齒，但我親妹妹四顆齊全。
I had all 4 until 12/2023 (43 at the time), when I cracked my bottom right WT on an unpopped popcorn kernel. I got the 3 others removed to balance my bite.
2023年12月前都保留著四顆智齒（當時43歲），結(jié)果右下頜那顆被沒爆開的玉米粒硌裂了。為了咬合平衡，干脆把剩下三顆也拔了。
I didn't develop bottom wisdom teeth, but I remember when my tops came in. I will never complain when babies cry over teething, as I was a 22yo crying teething baby lol. But I still have them! They're crooked (turned out) but they fit.
沒長下頜智齒，但上頜兩顆萌出時，22歲的我哭得像個長牙的寶寶。現(xiàn)在終于理解嬰兒為什么哭鬧了！不過這兩顆雖然長歪了，倒也不礙事，就這么留著。
I only had 2 wisdom teeth. My dentist had a different slant on it, he said we don't need them so eventually people won't have them. That was 50 years ago!
我只長過兩顆智齒。50年前牙醫(yī)就說過：這牙齒沒用，人類遲早會進化到不長智齒。

I got them removed with proper surgery after ten years of braces. After surgery it looked like I had a ping pong ball growing out my gums. At least I had ice cream and two days off school.
戴了十年牙套后做手術(shù)拔智齒，術(shù)后牙齦腫得像塞了乒乓球。不過能名正言順吃冰淇凌、請兩天病假也算值了。
Half my high school had the wisdom tooth extraction surgery around the same time. The teachers were amused at who handled pain in interesting ways. I would often turn into a growling little ball around lunchtime. To this day, I cannot stand mushy noodles or rice or American pudding.
高中時半個年級集體拔智齒，老師們圍觀大家千奇百怪的忍痛方式。我那會兒每到飯點就縮成團哼哼，至今看到糊狀面條、米飯或美式布丁就反胃。
I have 3 and I'm glad I have them. I've had 2 molars taken out and the wisdom teeth have moved forward into their place. I still have one on the bottom not fully erupted but it's not harming me, so it can just stay there until I need it. I don't see the point in removing teeth for no reason. Especially when there are risks associated with extraction.
我有三顆智齒且很慶幸留著。之前拔過兩顆臼齒，智齒就往前移位補了缺。雖然下頜那顆沒完全萌出，但既然不礙事就留著唄。實在不理解沒事找事拔牙的邏輯，何況手術(shù)還有風(fēng)險。
I had a dentist, 20 years ago, tell me that I'm more "evolved" because I had no wisdom teeth.

I just had my last Wisdom Tooth extracted a couple months ago and there was no laying on the couch, didn't even take a single day off work, and certainly no Ice Cream. Eating anything that cold sounds like an insane and painful idea.
兩個月前拔完最后一顆智齒，既沒臥床休息也沒請假，更沒吃冰淇凌——想想都覺得冰的會痛死人好嗎！

I never felt a thing... One day they just started poking out of my gums, and started slowly coming out. I didn't even know what they were at the time (in my early 20's).
完全沒遭罪…20歲出頭某天突然發(fā)現(xiàn)牙齦冒尖，后來慢慢長出來。當時根本不知道這就是智齒。
I had one with a bend to it; took the dentist getting in there pretty hard to yank it out. Didn’t feel a thing, but I will never get the sound of scraping bones out of my head lol
有顆智齒帶彎鉤，牙醫(yī)費老大勁才拽出來。雖然不疼，但器械刮骨頭的聲響這輩子忘不了。
I had 1 wisdom tooth extracted in my early 20s and then all 3 at once extracted at 27. I'm fortunate my body heals quickly so I was over it in a few days but still crazy to think about
20出頭拔了一顆，27歲又一口氣拔三顆。好在恢復(fù)快，幾天就沒事了，不過現(xiàn)在回想還是覺得離譜。
I developed wisdom teeth on the left side. I had them removed at age 27 shortly after they came in. 2 years later I had TMJ surgery on the left side of my jaw.
左側(cè)長過智齒，27歲剛萌出就拔了。結(jié)果兩年后同側(cè)下頜關(guān)節(jié)還得動手術(shù)。
I got all 4 of mine pulled due to proof pushing/crowding all of my front teeth and jawline. Making a functioning tooth line possible.
因為智齒擠壓前牙和頜骨，四顆全拔了，這才讓整口牙排整齊。
I had six wisdom teeth, which really impressed my oral surgeon, who said it was a one in a million mutation. One was so impacted that it snapped into pieces while he was cutting it.
長過六顆智齒，驚呆了我的外科醫(yī)生，說是百萬分之一的變異。有顆阻生齒太頑固，切割時直接碎成渣。
When I was 21, my dentist convinced me to have my wisdom teeth removed even though they weren't impacted. Later in life, because I am disabled and low income, I couldn't afford dental care and have lost all my upper molars. If I hadn't been convinced to have those teeth removed, I would at least have a couple of molars to chew with. In my experience, Income is a huge factor and dentistry should consider these issues before preemptively taking unnecessary and costly action.
21歲時被忽悠著拔了非阻生智齒。如今作為低收入殘障人士，無力負擔牙科治療，上頜臼齒全掉光。如果當年留著智齒，至少還能用它們咀嚼。親身經(jīng)歷證明：經(jīng)濟狀況是重大影響因素，牙醫(yī)不該輕易建議這類昂貴且不必要的手術(shù)。
I was born with 4 extra wisdom teeth. My surgery and recovery was an extremely painful experience for me and the doctor who had never seen that before.
天生多長四顆智齒，手術(shù)和恢復(fù)過程極其痛苦，連醫(yī)生都說從沒見過這種情況。
I had 2 wisdom teeth buds removed (uppers) when I was 12 prior to getting braces, because the dentist could see they were going to be impacted. Unfortunately, the ones that remained did end up being impacted and had to be removed by breaking and taking out pieces because the roots were entangled with the 2nd molars' roots. It was ugly, painful, and my cheap insurance company paid for Novocain but no other anesthesia. My dad still has 2 of his because of how complicated it would be to remove them.
12歲戴牙套前就拔了上頜兩顆智齒牙胚（預(yù)測會阻生）。結(jié)果剩下的還是阻生了，最后只能敲碎拔除，因為牙根和第二臼齒糾纏不清。過程血腥痛苦，破保險只給報局麻費用。我爸到現(xiàn)在還留著兩顆智齒，因為拔除難度太大。
I had wisdom teeth but one of them cracked and got pulled. Then when I got a new dentist, he opted to have the rest pulled after another decided to become impacted.
原本留著智齒，結(jié)果一顆開裂被拔。后來換新牙醫(yī)，另一顆開始阻生，干脆全拔了。
I'm 26 and only one of these bad boys seems to be doing anything at all. I hope he stays under my gums and stops growing.
26歲了，四顆智齒里只有一顆在搞事情。求求它安安分分待在牙齦里別長了。

認識個下顎寬大的朋友，人家智齒長得舒舒服服，根本不用拔。
I only had 3, and one was impacted so the common procedure in Canada is to remove all when one is needing removal. Removing the two that weren’t impacted noticeably altered my face symmetry. I would caution others against getting unnecessary surgeries unless there is significant cost savings (in this case there wasn’t and I wish I would’ve said no to the other two teeth that were chillin)
加拿大常規(guī)做法是只要拔一顆阻生齒，就得把其他全拔了。我三顆智齒中一顆阻生，結(jié)果拔完兩顆非阻生的后，臉型明顯不對稱。現(xiàn)在想來，除非能省大錢，否則真不該做這種不必要的手術(shù)。

19歲向常去的牙醫(yī)抱怨牙疼，他懶得拍片直接診斷夜磨牙，推銷300美元護齒套。我拒絕后轉(zhuǎn)診正畸醫(yī)生，結(jié)果X光顯示三顆埋伏智齒！果斷換診所，最后拔了四顆前臼齒、三顆智齒，還切了舌系帶（小時候牙醫(yī)說靠語言治療能拉長，根本沒用）。
Both my wisdom came out impacted and caused decay to the next tooth on both sides
兩顆阻生智齒把鄰牙都頂蛀了。
