Description

An open bite is a type of malocclusion where the front teeth do not touch when the mouth is closed, leaving a visible gap that can affect chewing, speech, and appearance.

Details

Open bites are often caused by habits such as thumb-sucking or tongue thrusting and can impact both dental function and aesthetics. They can lead to mouth breathing, speech impediments, and bite dysfunctions, particularly if left uncorrected.

Causes

Commonly caused by prolonged thumb-sucking, pacifier use, tongue thrusting, or inherited jaw development patterns. Skeletal issues may also contribute.

Symptoms

Gap between upper and lower front teeth, lisping or unclear speech, difficulty eating, and strain on back teeth.

Treatment

Treatment may include orthodontics (braces or aligners), myofunctional therapy, or surgery in adults with skeletal causes.
