Hypodontia is a defect in which one or more teeth are missing because of a problem with development, rather than trauma. We know that genetics plays a strong role, as hypodontia tends to run in families. The condition may occur alone or as part of a syndrome that causes other physical abnormalities.

The Craniofacial Center is currently conducting a study on hypodontia to identify genetic causes of the condition. If you would like to take part in the study, please send an email to Dr. Ophir Klein at [email protected].

A dentist or medical geneticist — a doctor specializing in genetic diseases — can diagnose hypodontia by examining your child.

Treatment for hypodontia generally involves a combination of orthodontic interventions, such as braces to align teeth or correct spacing, as well as prosthetics, such as dental implants or bridges, to replace missing teeth.

To get the best results from treatment, we recommend consulting with the Craniofacial Center as soon as your child is diagnosed.
