What is hypodontia?
Hypodontia is the congenital absence of teeth (from 1 to 6 teeth, both primary and secondary). It's one of the commonest anomalies dentists encounter in their practice. According to the statistics, hypodontia affects from 3% to 9% of the population. The most common missing teeth are mandibular second premolars, third molars and maxillary laterals. Aetiological basis of inherited tooth loss is little-studied, although much progress has been made in understanding the process of human tooth formation.
