Understanding the differences between overjet vs. overbite can help you identify which condition you may have and seek appropriate treatment.

December 20, 2024

Many people use the terms “overjet” and “overbite” interchangeably, but these orthodontic conditions are distinct issues that affect your teeth and jaw alignment. Understanding the differences between overjet vs. overbite can help you identify which condition you may have and seek appropriate treatment.

Let’s break down what overjet and overbite mean, their causes, treatments, and how to prevent them.

What Is an Overjet?

An overjet, sometimes called "buck teeth," occurs when the upper front teeth protrude horizontally over the lower teeth. This creates a noticeable gap between the upper and lower teeth when viewed from the side.

Key Features of an Overjet

  • The upper teeth extend outward beyond the lower teeth.
  • The horizontal distance between the upper and lower teeth is abnormally large.
  • It can make biting and chewing difficult.

Causes of Overjet

Overjet teeth can be caused by:

  • Genetics: Inherited jaw alignment issues.
  • Thumb-sucking: Prolonged thumb-sucking in childhood can push upper teeth forward.
  • Dummy Use: Excessive dummy use or bottle-feeding past infancy.
  • Tongue Thrusting: A habit of pushing the tongue against the teeth during swallowing or speaking.

Treatment for Overjet

Treating an overjet typically involves orthodontic appliances to reposition the teeth and jaw.

Options include:

  • Braces: Metal or clear braces can move the teeth into proper alignment.
  • Herbst Appliance: This device corrects jaw positioning by encouraging the lower jaw to move forward. Learn more about Herbst Appliance Treatment here.
  • Clear Aligners: Invisible aligners can gradually adjust the position of the teeth.
  • Surgery: In severe cases, corrective jaw surgery may be required.

What Is an Overbite?

An overbite, also known as a "deep bite," occurs when the upper front teeth vertically overlap the lower front teeth excessively. While a slight overbite is normal, a deep overbite can cause issues with biting and dental wear.

Key Features of an Overbite

  • The upper teeth cover more than 25% of the lower teeth when biting.
  • The vertical overlap can sometimes cause the lower teeth to touch the roof of the mouth.
  • It can lead to uneven tooth wear and jaw pain.

Causes of Overbite

Overbites can develop due to:

  • Genetics: Family history of jaw or teeth alignment issues.
  • Poor Habits: Thumb-sucking, tongue-thrusting, or prolonged pacifier use.
  • Jaw Development: Discrepancies in jaw size or improper growth patterns.

Treatment for Overbite

Similar to overjets, overbites can be treated with various orthodontic solutions:

  • Braces: To adjust the alignment of the teeth and reduce the overlap.
  • Bite Correction Devices: Appliances like retainers or rubber bands to reposition the jaw.
  • Clear Aligners: For milder cases of overbite.
  • Surgery: In severe cases, jaw surgery may be needed to correct the alignment.

Overjet vs. Overbite: Direct Comparison

Overjet

  • Direction: Horizontal protrusion of the upper teeth.
  • Appearance: Creates a gap between upper and lower teeth.
  • Causes: Thumb-sucking, tongue-thrusting, pacifier use, or genetics.
  • Concerns: Affects biting, chewing, and facial aesthetics.

Overbite

  • Direction: Vertical overlap of the upper teeth over the lower teeth.
  • Appearance: Upper teeth cover a significant portion of the lower teeth.
  • Causes: Genetics, jaw growth issues, or oral habits.
  • Concerns: Can lead to tooth wear, jaw pain, and gum issues.

Preventing Overjet and Overbite

While genetics can play a significant role, there are steps you can take to reduce the risk of developing overjet or overbite:

  1. Address Oral Habits Early: Discourage thumb-sucking and prolonged pacifier use in young children.
  2. Regular Dental Check-Ups: Early detection by a dentist or orthodontist can prevent issues from worsening.
  3. Maintain Good Oral Hygiene: Strong, healthy teeth are less prone to shifting.
  4. Early Orthodontic Intervention: Consult an orthodontist as soon as you notice alignment issues in your child.

How to Determine If You Have Overjet or Overbite

If you’re unsure whether you have an overjet, overbite, or neither, here are a few tips:

  • Check Your Teeth Alignment: Look in the mirror. Does your upper jaw noticeably protrude forward? You might have an overjet. If your upper teeth vertically overlap your lower teeth significantly, it may be an overbite.
  • Consult an Orthodontist: An expert can diagnose and recommend the best course of treatment. At Hampstead Orthodontic Practice, we specialize in diagnosing and treating various orthodontic issues, including those related to overjet and overbite.
