Overjet, a common dental malocclusion, affects millions of individuals worldwide, compromising their smiles’ aesthetics and functionality. Characterized by the upper front teeth protruding beyond the lower front teeth, overjet can lead to difficulties with biting, chewing, and speaking, as well as increased risks of tooth wear and TMJ disorders. With various causes, including genetics, habits, and developmental issues, understanding overjet’s complexities is crucial for effective diagnosis and treatment. 

This article delves into the causes, effects, and treatment options offered by the orthodontist in Irving, TX for overjet, providing valuable insights for individuals seeking to address this dental concern and achieve a healthier, more confident smile.

What is overjet?

Overjet, also known as protruding teeth, is a dental malocclusion where the upper front teeth extend significantly beyond the lower front teeth, exceeding the normal 2-4 mm overlap.

There are several types of overjets based on the measurement of protrusion:

• Mild overjet: 5-7 mm

• Severe overjet: >10 mm

Overjet may be caused by a combination of factors such as:

• Genetics: Inherited dental issues or facial structure.
• Thumb sucking or pacifier use: Prolonged habits can push front teeth forward.
