Generally wisdom teeth erupt most commonly between age 17 and 21. Eruption may start as early as age 13 in some groups and typically occurs before the age of 25. If they have not erupted by age 25, oral surgeons generally consider that the tooth will not erupt spontaneously by itself.

As we get older, these teeth shed and an adult human should have 32 teeth. Most people, however, have their wisdom teeth extracted and as a result end up with 28 teeth. Sometime teeth are also removed for orthodontic purposes or for braces. If you have too many teeth, this can cause problems with esthetics or crowding.
