Short answer: A deep bite does not always cause problems; but when it is pronounced, over time it can lead to wear of the front teeth, the lower teeth hitting the palate or the gums, gum irritation and difficulties with future treatments such as crowns. Whether treatment is needed is assessed by the clinician based on the amount of overlap and any symptoms.
What is a deep bite?
A deep bite is when, with the mouth closed, the upper front teeth cover the lower front teeth more than normal. In severe cases, the lower front teeth are barely visible. For more detail, see our page on deep bite treatment.
Problems that may occur if it is not treated
- Palate and gum trauma: The lower front teeth can hit the gums behind the upper teeth or the palate, causing sores and recession.
- Tooth wear: The front teeth rubbing against each other can wear down and shorten their edges.
- Risk of fractures and cracks: Enamel cracks may appear in teeth under excessive load.
- Difficulty with restorations: There may not be enough room when planning crowns, veneers or implants.
- Facial appearance: It can contribute to the lower face looking short.
Is it linked to the jaw joint?
The link between a deep bite and jaw joint problems varies from person to person and is scientifically debated. Clicking, pain or limited mouth opening in the jaw joint are assessed separately during the examination.
At what age is it treated?
In growing children, earlier intervention may be possible with appliances that guide jaw development. In adults, a deep bite can be corrected with braces or clear aligners by moving the teeth vertically; in skeletal cases, surgical options may also be discussed. For cases seen together with protruding teeth, you can read our article on protruding teeth and deep bite.
Quick questions
Does a deep bite correct itself?
Some depth can be normal in the baby-tooth stage; but a pronounced deep bite in the permanent teeth usually does not correct itself.
Can a deep bite be treated with clear aligners?
Many deep bites can be treated with clear aligners; suitability depends on the condition of the teeth and jaws.
Does a deep bite cause teeth clenching?
It cannot be said to be a direct cause; however, in people who clench their teeth, wear may progress faster.
How do you find out what suits you?
