Overjet: Understanding and Treating Protruding Front Teeth

What is Overjet?

Overjet refers to the horizontal distance between the upper front teeth and the lower front teeth. A normal overjet is about 2–3 mm, but when it exceeds this range, it is considered excessive and may require treatment.

Causes of Overjet

Several factors can contribute to overjet, including:

  • Thumb sucking or prolonged pacifier use.
  • Genetics and jaw structure.
  • Missing or misaligned teeth.
  • Poor oral habits such as tongue thrusting.

Problems Caused by Overjet

An excessive overjet is not just a cosmetic concern. It can lead to:

  • Difficulty biting and chewing.
  • Speech problems.
  • Increased risk of dental trauma (front teeth more exposed).
  • Low self-confidence due to appearance.

Treatment Options for Overjet

  • Braces: Traditional or ceramic braces gradually move teeth back into alignment.
  • Clear Aligners: Suitable for mild to moderate cases of overjet.
  • Corrective Jaw Surgery: Required for severe skeletal discrepancies.
  • Early Orthodontics: Interceptive treatments in children can reduce the severity of overjet later in life.

Preventing Overjet in Children

Parents can help by discouraging prolonged thumb sucking, promoting good oral hygiene, and seeking early orthodontic evaluations.
