So if you find yourself hiding your smile or fussing over crooked teeth, Urban Smile is here to encourage teens and adults to start their smile journey by sharing more about common orthodontic problems like overjet.

Quick Summary

  • Overjet (also known as “buck teeth”) is a common orthodontic condition that involves the upper front teeth to protrude outward in an angular manner over lower teeth. 
  • Overjet is caused by several factors such as genetics, thumb-sucking, tongue-thrusting, and persistent swelling. While it is a common condition, it’s important to learn your treatment options by consulting with an orthodontist.
  • Clear aligners improve smiles and offer a conveniently discreet way to straighten overjet teeth and extend several benefits for your appearance, oral health, and overall well-being.

What is Overjet?

Overjet is a common orthodontic condition1 that happens to anyone at any age. Nicknamed the term “buck teeth”4, it occurs when your upper front teeth protrude outward in an angular manner6 over lower teeth. The misalignment may affect appearances as well as lead to difficulties in mouth function.

Overjet is also often confused with an overbite. While they both involve protruding teeth, an overbite involves a distinct vertical distance between the front upper and lower teeth whereas an overjet displays a horizontal difference between the two sets.

At Urban Smile, we understand how an overjet can be uncomfortable in everyday situations. Learning about the causes of overjet can create self-awareness to oversee habits that may lead to or worsen your oral health. Our qualified, experienced, and dedicated team of dental experts provide excellent orthodontic solutions and treatment for overjet issues.

What Causes Overjet?

Hereditary Jawbone Structures or Teeth Arrangements

Overjet can be hereditary3. Like every other part of our body, genes are a factor to consider as they can pass on specific jawbone structures or certain teeth arrangements that may cause the form of overcrowded or misaligned teeth that eventually develop through the years.

Thumb-Sucking, Pacifiers, and Prolonged Bottle FeedingA Baby with a Pacifier

While thumb-sucking or pacifiers are considered self-soothing for children, overjet is developed by the continuous pressure that causes damage even after the baby teeth are off; more especially when the habit goes on beyond the age of 5.


Similar to thumb-sucking, the pressure that comes from tongue-thrusting2 can cause teeth to be continuously pushed outwards causing malformed teeth, gaps, open bites or overjet. Oftentimes, overjet occurs when tongue-thrusting is present during early oral habits of swallowing or unconsciously in sleep or times of stress.

Swelling, Lumps, or TumoursA Woman Experiencing Overjet Problems

When jaws change shape, they cause teeth to realign themselves to follow how the mouth or jaw are positioned. Any form of persistent swelling or growth such as lumps or tumours, whether soft tissue or bony, can be a factor to overjet causing parts of the mouth or jaw to shift teeth outward. 

Skeletal Discrepancy 

Skeletal discrepancy can cause overjet when there is an incompatibility5 of the jaw bone that may cause teeth to shift or protrude outwards.

5 Reasons to Treat Overjet
