MIH is a condition where the enamel and dentin are softer than normal (hypomineralized). This leaves the teeth susceptible to tooth decay.

Causes

The cause of MIH is not fully understood. Many believe that there is a disturbance in tooth development in the third trimester, at the time of birth or first few years of life. Some suggest these disturbances to be caused by severe childhood illnesses, high fevers, or birth prematurity.

Signs and Symptoms

One, some or all first adult molars, incisors and canines can be affected. These teeth may have discolored and appear cream, yellow or brown. The teeth may be painful or sensitive.

Treatment

Treatment options include but are not limited to fluoride varnish application, Icon resin infiltrate, or fillings. A thorough examination is recommended to evaluate the extent of hypomineralization and treatment options that will best fit each patient.
