Why do we have wisdom teeth and then eventually they have be to pulled out?

Most adults don't have room in their mouths for them, causing the other teeth to crowd.  \nMore importantly though, the wisdom teeth roots will grow into your jawbone eventually and your jaw will have to be broken to have the teeth removed.

I think you should remove them.  Life is easier after you remove them.  \n\nWhile all the scientific studies, and dental lecturing above is true.  It doesn't really help you deicide does it. \n\nWhen I talk to people who come in to my office they often think there hygiene is pretty good.  But, for whatever reason, work, family, and or school, they have not gone to the dentist for a while.  \n\nYou know where I find the most catastrophic decay?, if any.  usually in the back teeth, between the 2nd and 3rd molars, or 1st and 2nd molars.  People can't floss back there.  When you brush your teeth you look in the mirror and see the front teeth and the back teeth are just glanced over. \n\nWhen big cavities do occur between the 2nd molars and the wisdom teeth is almost always the 2nd molars that need all the work.   If they are pulled you are left with these big useless wisdome teeth hangout back there.  So why not remove the wisdom teeth and get rid of those back liablities to tip the hygiene equation in your favor.  If you have less to clean you may make it back there more often.  You know what they say every little bit helps.\n\nAnother benefit is that without those babies back there your jaws become a lot more mobile since the wisdom teeth are not there to rub against the jaw bone. \n\nGood luck in your decision.  It's really not easy to make the decision to get them removed. But the need to get them removed is valid.

Why remove a wisdom tooth?\n\nhttp://www.members.aol.com/swf08302/wizdk.jpg shows one reason.  This is what can happen by the time you are 40 or 50 if you leave a wisdom tooth in place when it is impacted.  The red arrows on the x-ray show the grey area that has decayed due to the wisdom tooth being present under the gum.  The tooth shown is the exact same tooth shown in the x-ray, but turned so you can see the cavity.  Food and bacteria can get down there and you can't clean it out.  Eventually, it makes a cavity in the tooth next to the wisdom tooth and makes it so you have to have BOTH teeth removed.

If a tooth requires a  root canal, and you don't want it, the only other option is removal of the tooth. \n\nModification:\nForgot to say that usually, wisdom teeth are removed...root canals aren't done on them.

My wisdom teeth did not completely come in until I was in my 20s.  They took forever to fully grow in.  I did not have to get them removed.  But because they are so far back in my mouth, it is a challenge to brush them properly.  Four years ago I got a cavity on the surface of one facing the back of my mouth.  The dentist could not reach it to fill it (partly below the gum line) so he pulled the tooth.  It was in the top of my mouth, he only used Novocaine.  The noise of the extraction was horrible (crunching) but the pain was minimal.  The upper molars only have one central root. The bottom molars have four roots on each corner.  Most complications arise from not completely getting all of the roots out, dry bone (when there is not flesh over the extraction site), and infection.  Also some people have bone in the way of the extraction or it is damaging nearby teeth.  After my extraction, my dentist used a laser to cauterize the wound and kill the bacteria.  I went home that day with Tylenol and was a little sore for a couple of days, but it was not that bad.

um, we dont really need it.  lol @ the guy above who said that we lose 35% intelligence. \nBut why do u want it removed? \nI had crowding in my teeth, and i got braces. I had to get my 4 wisdom teeth removed. But, you should get it removed one at a time. These are really permanent and deep rooted teeth. Im sure ur dentist would not remove them all at once. I had to get stiches for the removal of 2, it was that hard to get it out. \n\nIf it doesnt create trouble then dont. Do you really want to be stuck with sedative injections in ur gum and then having it being pulled with force if not required? ( and the injections really hurt, when they push the medicine in. They stick u 2-3 times). 2 of my wisdoms removed easy, in about 5 mins of pulling. The other 2 were a real pain. took 30 mins, they had the suction machine to suck the bleeding that was there (it was alot). They drilled it with a machine to split the tooth in 2 pieces as it was deep rooted. The drilling hurt alot, depite the sedative injections they gave. It really hit the core of ur nerve. They then stiched it up. \nAfterwards,  u cant really eat freely for a few days. Your mouth would obviously be swelling alot. And you would have to take anti-biotics tablets to prevent infection. (which means, u could get  and that would be worse case senario).\n\nSo if u dont have a choice, then u dont. If u do, its all a matter of if u want to go through the not very nice proceedure :)

WISDOM TEETH: IS IT WISE TO REMOVE THEM?\n\nCommon misunderstandings surround their name origin, removal reasons and pain sources\n\nWisdom teeth, also known as third molars, are the last teeth to grow in the back of\nthe mouth. Common misunderstandings surround their name origin, removal reasons and\npain sources, according to the Academy of General Dentistry, an organization of\ngeneral dentists dedicated to continuing education. \n\n"The name 'wisdom teeth' is age related - third molars don't erupt until teenage\nyears and beyond, when people theoretically are more wise to the world," says Trey\nPetty, DDS, FAGD, spokesperson for the Academy of General Dentistry.\n\nCommon reasons for wisdom teeth removal include impaction, pain and crowding of the\nother teeth, which are typical tooth growth characteristics.\n\n"If wisdom teeth are not visible, they are impacted or unable to erupt due to space\nand size limitations," says Dr. Petty. "Impacted teeth don't have enough room to grow,\nand will lay beneath the gums, which may or may not be a problem." \n\nPain and tooth crowding are also top wisdom teeth problems. "Adults have forgotten\nwhat normal pain from a growing tooth feels like," says Dr. Petty. Complications also\ncan arise when wisdom teeth partially erupt. The broken gum acts as a breeding ground\nfor bacteria and germs. \n\n"When wisdom teeth partially erupt, food gets caught in the gums and may cause an\ninfection, swelling, growth of a tumor or cyst and pain," says Dr. Petty. "If this\nhappens, consult a dentist before problems worsen and affect overall oral health."\n\n"If wisdom teeth have erupted, the key to preserving them is maintaining good oral\nhealth by brushing twice a day and going to see a dentist twice a year," says\nDr. Petty.

No.  Your wisdom teeth can stay in your mouth if they are in the correct postion to fall down next to your other molars.  However, most of the time, they grow in at an angle and will impact the molars around it, thus having to be removed.

Some people don't get them at all. One of mine didn't come in until I was in my 20's. I don't have dental insurance, so it is still there just hanging around with the rest of my teeth.  \nI think way back humans had them because of the food that they ate, but now that humans don't have to eat the rough food, our mouths have adapted to not needing these teeth to eat.

Sometimes wisdom teeth are broken apart before they're removed to make the process easier than pulling the entire tooth out at once. In that case, there'd be no teeth to keep. But, if I was given the option, I'd keep one of them.\n\nAs far as getting them removed or not, that's something you'll need to talk to your dentist about. Depending on the structure of your mouth, it may not have room to allow for the extra teeth. If that happens and they aren't removed, either (1) your wisdom teeth will end up becoming impacted, meaning they don't (fully) come to the surface like they should or (2) your teeth will become crowded, meaning the wisdom teeth will push your other teeth out of alignment to make room for themselves. As you can see, neither scenario is great, particularly (1), as impacted teeth can cause infections, swelling, pain, and nerve damage.

I went to a dentist with minor face swelling from an abscessed third molar emerging incompletely.  He pulled it then and there after some numbing and using some awful terror tactics.  I do believe he thinks he's House from the TV show.  Severe swelling in your face can restrict your neck, thus slowing blood flow to your brain or your esophagus, limiting your airway.  Both of which could be fatal if left untreated, I recommend lots of ice packs, not moving around much and NOT waiting for the pain meds to wear off before taking a new round.  Your tooth did get pulled didn't it?  I wonder why they didn't take it immediately?

If your dentist says you have to do it, it's probably because they may crowd your teeth, cause pain, and--this is really serious-- create abscesses and/or get infected. If you're young (20s and younger), this is definitely the time to deal with it, you'll be given painrelievers and you should be up and about in no time. \n\nHowever, the older you get, the more chance that the surgery gets more involved and the recovery time slower. I would really urge you to get it done, because I waited too long myself. My dentist says it is now considered serious surgery for me and I may need a whole month to recover, and that's if there aren't complications! And why did I ask my dentist for it? Because my jaws now hurt in those areas, and my lower teeth are starting to crowd and get more cavities and stains.\n\nSo please, please don't put it off.

wisdom teeth are nothing but the 3rd molars , and is the last tooth to be errupted in the mouth , it erupts between the age of 17 - 21 years , not every person needs to to be pulled out , it depends whether the wisdom tooth has got suffiecient space for errupting in the space provided by your jaw , when ever there is insufficient space the wisdom tooth gets impacted and gives u pain and some times sweeling and infection of gums around the partly errupted wisdom tooth which is called pericorinitis . so the persons in which wisdom has got impacted, should get their tooth to be extracted .\n\n it doesn't fall out or exfoliate itself as its not a milk tooth , its a permanent tooth which errupts at age of 17 - 21

Because 'milk' teeth are deciduous teeth or 'baby' teeth and they are meant to fall out so that the permanent teeth can come in.  Milk teeth are not strong enough or large enough to function adequately in the adult dentition.

your making me think twice about getting mine pulled. i am glad i waited until after the holidays. it sounds like you could have an infection see your dentist,  but take some pain killers to hold you over until the holidays are done.

wayyyyy back when we were still developing in to homosapiens, these third molars grew in to help us eat food. but as evolution took place and our diets change, our bodies adapted. there was no longer the need for these third molars to rip, crush, grind and chew so the eventually stopped growing in consistently. now, they sometimes grow in, sometimes not. a person can have only one or all four come in and they might never erupt out of the gumline. the reason they become problematic is that our mouth is just not big enough to hold them anymore. look at pics of our early human ancestors and you can see their mouths and jaws are considerably larger than ours. i just got my only wisdom tooth out a few days ago! incredibly painful, it was really impacted. in the future, people will not have any wisdom teeth because evoluation will have taken care of this unnecessary trait.

Because you have nerves that go into your teeth.  When you have your teeth done, the nerves can become irritated.  It usually goes away pretty quick.
