You may not have a full understanding of what a crossbite is until you, or a member of your family, is diagnosed with one. There are two types of crossbites and both of them can lead to jaw pain, TMJ (Temporomandibular Joint Dysfunction), and other issues such as receding gums and loose teeth. These side effects are not things that anyone wants to deal with, but the good news is that crossbites are treatable. We take a look at what a crossbite is and how it can be treated.

What is a crossbite?
A crossbite occurs when there is a misalignment of your upper teeth in relation to your lower teeth. Crossbites can be hereditary, but they can also be situational. Crossbites that occur in children can stem from the permanent teeth growing in before all baby teeth have fallen out. If this occurs, the new teeth that come in cantgrow in place properly which results in misalignment issues. Most of the time however, crossbites stem from genetics. If your parents had issues with their bites, chances are they could have passed this down to you.

What are the types of crossbite?
There are generally two types of crossbites: anterior crossbites and posterior crossbites. A posterior crossbite is what occurs when your upper teeth fall inside your lower teeth on one side when you bite down. An anterior crossbite, which is similar to an underbite, is what occurs when your top front teeth fall behind your lower front teeth when you bite down.
Both types of crossbites can be corrected and the sooner they are remedied, the better.

What problems do crossbites create?
Crossbites that are left untreated can cause a host of health problems ranging from cosmetic issues, jaw grinding, receding gum line, the loss of teeth, and jaw issues. Some patients with crossbites report having headaches from the tension and stress that is beingplaced on the jaw. Additional tensions arise from teeth grinding due to misalignment and, in worst case scenarios, crossbites can even affect the way a patients face and jaw grow. These issues can all be preventedwith proper treatment options, especially when treated at a young age.

If you or someone in your family is living with acrossbite, the best course of action is to schedule a visit with your dentist for a full examination. Your dentist will be able to identify if a crossbite is presentand recommend the proper course of treatment.

What are crossbite correction and treatment options?
Most dental professionals would agree that the best time to correct a crossbite is as a child or teenager. There are treatments available for adults as well, but the earlier the crossbite is detected and treated, the better. Most crossbites are remedied by adjusting the teeth or jaw usingorthodontic treatmentsand appliances.

Here is a list of treatment options that are available to correct crossbites. Each individual case is different and requires an examination in order to determine the best course of action:

  • Maxillary Expander
  • Removable expander
  • Braces
  • Surgery in extreme cases


Many orthodontic professionals utilize a combined therapy of expanders and braces. The expanders work to create the correct amount of space in between the teeth so that the bites are aligned properly throughout the entire mouth. In adults, sometimes a removable expander can be prescribed that is only worn at night. Each case is different and will require its own treatment plan.
The best place to start is bytalking to your dentist aboutcrossbite correction and treatment optionsavailable to you or your child.
