What are wisdom teeth?
Wisdom teeth are the upper and lower third molars, located at the very back of the mouth. They are called wisdom teeth because usually they come in between ages 17 and 21-when a person is old enough to have gained some wisdom.
What causes problems with
Wisdom teeth that are healthy and in the right
position usually don't cause problems. You may
have a problem if any of the following occur:
Your wisdom teeth break through your gums only partway because of a lack of space. This can cause a flap of gum tissue to grow over them. The flap can trap food and lead to a gum infection.
They come in crooked or facing the wrong direction.
Your jaw isn't large enough to give them room. Your wisdom teeth may get stuck (impacted) in your jaw and not be able to break through your gums.
They are so far back in your mouth or crowded that you have trouble cleaning around them.
