Supernumerary Teeth

I once had a patient who told me has 3 incisors (front teeth) and  had these since her was 9 years old. This is a case of Hyperdontia -- supernumerary teeth.

The most common case for hyperdontia is the mesiodens, where there is an excess number of incisors especially on the upper teeth. Causes may vary but the most common is either hereditary or delayed eruption of the temporary teeth. Diagnostic methods like X-ray will confirm hyperdontia and will help dentists diagnose such case.
