Supernumerary teeth are abnormally developed teeth which are usually hereditary. They can erupt normally or grow towards the opposite direction, and are completely hidden inside the jaw bone. Supernumerary teeth usually appear in the area around upper front teeth.

The consequences of having Supernumerary teeth:

Disrupt the eruption of permanent teeth.
Delay the growth of permanent teeth.
Affect the position of the teeth.
Cause irregular alignment of teeth.

There is a projected and fragile tooth structure on the chewing surface of a Leong's premolar. If the projected tooth structure is fractured and left without proper treatment, the pulp of the tooth can be infected by bacteria and become necrotic, and can or even lead to periapical infection, that is an abscess.

When two teeth are united during the developmental stage by the union of their tooth germs, a fused tooth will be formed. There will be a groove on the surface of the tooth, and it is commonly found in deciduous front teeth. When there is a deciduous fused tooth, a succeeding permanent tooth may be missing.
