Mixed dentition is a stage that lasts 2-3 years. Permanent
teeth are the second set of teeth formed — there are thirty-two
permanent teeth. The first permanent tooth typically appears in the
mouth at around age six, and the mouth will then be in a transition
period with both deciduous teeth and permanent teeth, until the last
deciduous tooth is lost. The first of the adult teeth to erupt are the
permanent first molars that come through the gums at the back. Up to the
age of 13, twenty-eight of the thirty-two permanent teeth will appear.
The full permanent dentition is completed much later. The four last
adult teeth, one at the back of every arch will appear between the ages
of 17 and 25 years.
