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.
