Crossbite

Classification of Teeth Overview

For a brief overview of the classification of teeth, please click on the image below. It will launch our educational module in a separate window that may answer some of your questions about the classifications of teeth.

Crossbite can occur in the front and/or the sides of the mouth: One or more upper teeth bite on the inside of the lower teeth. This can occur with a single tooth or multiple teeth. Early correction of crossbite is recommended.

Crossbite should be corrected because it can:

  • cause premature wear of the teeth
  • cause gum disease including bone loss
  • cause asymmetrical development of the jaws
  • cause dysfunctional chewing patterns
  • make your smile less attractive

How can a crossbite be orthodontically corrected?

If there is a single tooth crossbite, the tooth can be moved with braces into the correct position. In some cases, a retainer can be utilized. With multiple teeth in crossbite, the arch needs to be expanded with braces or other intra-oral appliances.
