Is a space or gap between two teeth. Many species of mammals have diastemata as a normal feature, most commonly between the incisors and molars.
Symptoms:
A diastema that occurs because of a mismatch between the teeth and the jaw does not have symptoms. However, spaces caused by a tongue thrust habit or periodontal disease will tend to expand or grow with time. The teeth may become loose, and discomfort or pain may occur, particularly during biting or chewing.
