The first permanent tooth usually appears in the mouth at around six years of age, 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 last permanent tooth usually arrives at around 18 years of age, but this can vary greatly between individuals.
