Hypoplastic and Hypomineralised Teeth

The term "hypoplastic" means less quantity of enamel, and the term "hypomineralised" means less mineralised tissue. Basically this involves a tooth which is less mineralised therefore more porous. A hypoplastic tooth has reduced amount of enamel so the surface may be rough. Your child may have teeth which have developed in this manner.

The most common teeth to be affected are the second primary molars which erupt at the age of 2½ years or in the permanent dentition the first permanent molars which erupt at age 6.
