Why dont some people get their wisdom teeth?

im 24 and never got them, do u think they may still pop up. do some people just never get them, and if so why? i heard that the wisdom teeth were more useful thousands of years ago when early humans had to chew tough meats and things like that, but they are losing their importance now. maybe in a few generations people wont be bothered with them!

Why dont some people get their wisdom teeth?
NATALIE,





THE ANSWER TO THIS IS GENETICS. SOME PEOPLE HAVE 1 OR 2 MISSING, AND SOME DON'T HAVE ANY. THIS IS NOT THAT COMMON, BUT ONLY WITH A PANORAMIC X-RAY CAN PROVE THIS.





WHY DO YOU SAY THAT?





BECAUSE THE TEETH MAY BE IMPACTED BELOW THE GUMS WHERE THEY WOULD NEVER NATURALLY ERUPT.


WHETHER THESE THEETH WOULD NEED TO BE EXTRACTED WOULD BEST BE DETERMINED BY WHAT IS SEEN BY THAT X-RAY. A PANORAMIC X-RAY (radiograph) IS BEST FOR THIS.
Reply:I have wondered this myself. It seems to run in my family in females. We just don't have them, my g-grandmother, g-mother, mother, myself and my kids. Lucky US
Reply:You are better off without them. I had to have 1 of mine pulled, and I pulled the other one myself - not recommended. They serve no real purpose, as you say, and you are better off without them. They are a pain - literally!
Reply:It's pretty much the luck of the genetic draw. I only had two wisdom teeth, and my sister doesn't have any. At age 24, if you had wisdom teeth, you would at least be able to see "buds" growing under the surface of the gums in a panoramic x-ray. If they're not present by now, I suspect you don't have them. Count your blessings - you'll never have to have them removed!
Reply:Wisdom teeth suck. I have an absesced one right now. But to answer your question everyone has wisdom teeth. Yours just haven't sprouted out. It's what we call impacted. Wisdom teeth truely are pointless though because they are a result of evolution. The cavemen needed them so they have been passed onto us.
Reply:I doubt your wisdom teeth will just "pop up" out of no where. When was your last dental x-ray? If you had wisdom teeth developing, the dentist would notice years before they erupt.





More and more people do not have wisdom teeth. The majority of people who do have wisdom teeth need to have them removed. I think we are evolving and eventually no humans will have wisdom teeth. Even though we don't need wisdom teeth, evolution takes a long, long time. Sounds like you are more evolved than the rest of us!
Reply:I am 27 and i don't have mine cause their impacted all 4 are on an angle underneath my back teeth they will never come up the dentist recommended i have them taken out especially before i hit 30 apparently they are a ***** to get out then, i haven't did it yet iam to much of a chicken ****, yours may be impacted as well.
Reply:what you've heard is right.


some people have got all the four wisdom teeth, others may have none. they may even pop up at a later age, there's no rule to it but it's better not to bother with them at all.


they are usually very sensitive teeth, pop up in various directions and create lots of problems which finally finally lead to extraction.
Reply:Hi, I'm Josie an ex dental nurse. You are almost right, through evolution and good oral hygiene you do not need them as the teeth we have now last for the time that we are alive.So with time some people stop developing them, some have them but have no room for them to erupt and some unfortunate people have them partially erupt and that's when you will need to have them removed. the only way for you to see if you have them is to have an x ray taken by the dentist
Reply:Humans will never "evolve" out of having wisdom teeth. That's not how evolution works. They will always be there, in the same way that if you chopped off every human's left arm when they turned 24, humans would still be born with left arms until the end of time.


Some may just not come to the surface and therefore aren't a problem. But they probably were a problem in the caveman ages.





SORRY but this IS true. Evolution, by definition, is the killing off of weaker genes. The fact that we still have appendixes even though we don't use them proves MY point, not yours: that just because we don't use them doesn't mean they'll go away.





Evolution: There are purple rats and brown rats. Brown rats blend in to the environment. Purple rats stand out. Purple rats get eaten by owls because they are seen easier. Brown genes survive, purple genes disappear.





Basically, a gene has to be "killed off" in order to disappear from evolution.


Since there is no DEATH from wisdom teeth, wisdom teeth don't DIE out. I am right. Ask ANY scientist. Or your orthodontist.
