Toothy Questions: What’s an Overjet?

An overjet is a type of malocclusion. It is when the top teeth protrude out in front of the bottom teeth.

Why can this be a problem?

There are a number of reasons why a dental overjet can be an issue. One of the major reasons for people to want to address their overjet is that it can make them feel very self-conscious about their smile.

Incorrect alignment of the top teeth will also mean that the back molars aren’t sitting in the correct place. This can make it almost impossible to have a good bite, and a poor bite is likely to result in premature wearing of the teeth.

In some cases, protruding upper teeth can also make them more at risk of injury during sports or as a result of a fall. This is because teeth can be less well protected when they are out of alignment with other teeth.

What causes an overjet?

An overjet often happens as a result of poor jaw development. This is usually genetic.

However, in some cases an overjet can be caused when children and teenagers continue to suck their thumb after their adult teeth have come through.

How can an overjet be corrected?

Luckily, it’s reasonably straight-forward to correct an overjet. Teeth realignment treatment with either a fixed or removable brace can address these problems and gently move protruding top teeth back into a more favourable position.

In cases where the patient has a more severe overjet, they may have more limited choices for which type of brace is right for them. A traditional fixed or lingual brace is likely to be the right option in these cases.

Do you have an overjet?

If you or your child has an overjet that you’d like to address, we recommend that you talk to a specialist orthodontist to get a personalised treatment recommendation. Here’s where to find a trusted orthodontic practice close to you.
