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.
Medical Definition of Primary teeth Primary teeth: The first teeth which are shed and replaced by permanent teeth. The first primary tooth comes in at about 6 months of age and the 20th and last primary tooth erupts at around 2 1/2 years of age. The primary teeth are replaced beginning usually at about age 6. Also called baby teeth, milk teeth, temporary teeth or deciduous teeth. (In Latin, decidere means to fall off or be shed, like leaves from a tree).
