Yes, it is common.
Just as with tonsils, it is normal for a young child have large adenoids, and the simple fact that the adenoid pad is large is not a reason for surgery. Babies are born without visible tonsils and adenoids. The adenoids begin to grow in the first year of life, peak in size between age one and five, then slowly get smaller as a child grows. While the occasional teenager may still have adenoids big enough to cause blockage of the nose, this is rare and the adenoids typically shrink away before adolescence. http://www.kids-ent.com/website/pediatric_ent/tonsils_adenoids/index.html
Yes, wisdom teeth or 3rd molars are the most commonly missing or deformed teeth.
Not necessarily. Teeth tend to become more crowed as we age, especially the lower front teeth. This happens in some people regardless of whether they have wisdom teeth or not. Therefore, removing the wisdom teeth, solely for the purpose of hoping to get naturally straighter teeth, won't work.
yes you do
No
Not all people get their wisdom teeth. Some get all four wisdom teeth, some get just one, and others have some that never erupt.
Your wisdom teeth are the teeth in the waaayy back of your mouth, top & bottom. Some people lose them, some people don't. They usually don't fall out, though.
An adult that had they're wisdom teeth pulled or not come through then you have 32 teeth. But if you still have your wisdom teeth you have 36.
Absolutely.
There are four wisdom teeth in a normal human being. Wisdom teeth are the very last four teeth that grow. They grow at the very end of the jaw - two upper and two lower. Wisdom teeth start appearing in the teens. Wisdom teeth can also appear towards the end of teenage. If there is no space in the jaw for the teeth to come out, then these are removed.
yes they have two extra wisdom teeth
We have four, two on the top and two on the bottom. i was a really weird case but i had 3 on the top and 4 on the bottom, so 7 in total i got mine out last week, all of them, and it has been a total nightmare. Normally there are four. But there are exeptions, some people have wisdom teeth missing. Other people have surnumerary teeth, meaning extra wisdom teeth.
I spoke to my oral surgeon about the crowding in my lower jaw that I believed to be caused by my wisdom teeth. He said that even with the extra space I would receive from the removal of my wisdom teeth, it would be unlikely that my teeth would move back into place. There was mention of being fitted for retainers and going to a different doctor who specialized in orthodontics.
