An overbite, also called a deep bite or closed bite, is a type of malocclusion. It is characterized by the upper front teeth protruding excessively over the bottom front teeth when back teeth are closed.
What are the causes of a deep bite?
The lower jaw is shorter than the upper jaw
This is the most common cause of a deep bite. Whether small or large, the upper and lower jaw need to be of relatively similar size for the teeth to develop correctly. When the lower jaw is considerably smaller than the upper jaw, the teeth grow differently. With a proper bite, the upper teeth overlap the lower teeth slightly. When the mouth is closed in an ideal bite, about one-half to two-thirds of the length of the bottom teeth will be revealed.
With an overbite, the front lower teeth grow up under the top ones toward the top of the mouth behind the front teeth. Malocclusion can be a genetic condition. Or it can arise over time because of secondary conditions.
Missing lower tooth
In some circumstances, a missing lower tooth can cause the jaw to move over time and create an overbite.
Teeth grinding may lead to malocclusion including an overbite.

Can an orthodontist correct an overbite with braces?
Yes, orthodontists use braces to correct overbites. Skilled orthodontists correct all types of malocclusion, regardless of the cause. It’s essential for young children to be evaluated by an orthodontist to diagnose bite issues early.
Do you think you are too old to fix an overbite with braces?
While it’s easier to move teeth when they are young, orthodontists treat bite problems in patients of all ages. Even individuals in their 70’s and 80’s have improved their quality of life by correcting malocclusion.
