Wisdom teeth, also known as third molars, are the last teeth to grow in the back of the mouth. The third molars usually will try to grow in at around age 17 to 21 years. Since that is considered to be the age when people become wiser, third molars gained the nickname, "wisdom teeth."
Actually, they are no different than any other tooth except that they are the last teeth to erupt, or grow into the mouth. They are just as useful as any other tooth if they grow in properly, have a proper bite relationship and have healthy gum tissue around them. Unfortunately, this does not always happen.
Common reasons for wisdom teeth removal include impaction, pain and crowding of the other teeth. Complications also can arise when wisdom teeth partially erupt. The broken gum acts as a breeding ground for bacteria.
Unless they grow in properly, third molars should be evaluated for extraction before complications arise.
