Teeth are named by their set, arch, class, type, and side. Teeth can belong to one of two sets of teeth: primary (baby) teeth or permanent teeth. Often, deciduous may be used in place of primary, and adult may be used for permanent.
By 12 months babies usually have 4 to 8 teeth. By 18 months 12 teeth and by 3 years all 20 baby teeth will generally be in place. Baby teeth will be lost between the ages of 6 and 12 years to make way for permanent teeth (also called adult teeth). Teeth generally appear in a certain order.
