When there is a case of hypodontia of the permanent premolar teeth, the primary molar teeth would often remain in the mouth beyond the time they are meant to be lost.

In these cases, teeth may lose their weakened enamel shortly after eruption and are highly susceptible to dental caries. Affected teeth are highly sensitive to chemical and thermal irritants, and may also be difficult to obtain anesthesia. The causes of MIH are thought to be similar to those of other forms of enamel hypoplasia, but occur ...
