Anodontia is a dental condition characterized by complete absence of teeth. The primary (baby) or permanent (adult) teeth may be involved. Anodontia is extremely rare when present in a pure form (without associated abnormalities). In most cases, the phenomenon is associated with a group of conditions called the ectodermal dysplasias. In these cases, abnormalities are also noted in the hair, nails, and sweat glands. Anodontia is an autosomal recessive condition. A specific gene has not yet been identified. Treatment involves replacement of the teeth with dentures or implants.
