According to the British Dental Association, there are deciduous molars, all of which eventually fall out by around age 12, and permanent molars, which do not necessarily fall out. All the deciduous molars appear by the time a child is around 2 1/2 years old.
The British Dental Association states that the first permanent molars begin coming through at around 6 years of age. This is also the time when the deciduous teeth begin to fall out. By age 13, most individuals have 28 permanent teeth. The wisdom teeth or third molars tend to appear, if at all, between ages 17 and 21.
