At what age do teeth stop growing?

Never: Really, teeth never stop growing. The basic answer is that most crown growth is completed before the tooth pushes through the gum. The root growth is completed within two years after the tooth pushes through the gum. Internal changes in the pulp chamber and root canals continue throughout the life of a healthy vital tooth.

Variable ages: Females erupt teeth 6 months to a year before males -between 17-21in females third molars are erupting-males 18-21-by 21all teeth should be erupted if a tooth bud is present.Now this is not universal because in some west african countries I have seen third molars erupted at age 13-15.

Teeth Growing: On average people have a full set of teeth at age 12 or 13 with the exclusion of the wisdom teeth that appear at age 18-20.
