What is a diastema?

A diastema is a gap (wider than 0.5 millimeters) between the teeth. It can appear in both children and adults. It is not harmful. In children, the gap usually closes when their permanent teeth erupt. In most cases treatment is not necessary except for cosmetic reasons. In fact, some people are recognized for their diastema.
