What is a Crossbite? (Part 1)

– Thursday, January 16, 2014 –

We have many patients who are referred by their dentist because their teeth are in "crossbite".  Crossbites can occur with either baby teeth or adult teeth and usually require orthodontic treatment for correction.  In Part 1 we focus on the most common questions patients and parents have about crossbites and show some examples of patients with crossbites.  Part 2 will highlight before and after photos of patients with crossbites who were treated by Dr. Jill Mioduski.

What is a crossbite?

A crossbite is a type of malocclusion where one or more of the top teeth bite inside of the bottom teeth instead of outside.

Are there different types of crossbites?

There are different types of crossbites and they depend on the location in the mouth:  

  • Anterior crossbite:  crossbite of one or more of the front teeth
  • Posterior crossbite:  crossbite of one or more the back teeth

Why is it important to correct a crossbite?

Correction of a crossbite can benefit you in many ways.  If left untreated, a crossbite has the potential to cause:

  • Excess wear of the teeth
  • Abnormal tooth position with damage to the gum tissue
  • Unwanted jaw position or jaw growth
  • Worsening of the bite over time

How is a crossbite fixed?

Orthodontic treatment is usually required to correct a crossbite which may include braces and additional appliances depending on your specific needs.
