How to fix a crossbite?

Have you noticed that a few of your child’s upper teeth have grown behind their bottom teeth instead of in front? This is a common orthodontic issue in kids, and it is called a crossbite. Although there are many forms of crossbite, each has its own effect on your child’s bite and confidence.

Usually, a crossbite involves just a few of your child’s upper teeth growing slightly behind or inside their lower ones, but sometimes the misalignment can be larger. Whatever the severity, crossbites can grind down your child’s teeth, affect their smile and potentially even harm their gums or affect their jaw growth.

Luckily, crossbites of all kinds can be fixed with the right orthodontic treatment. Here are the answers to some frequently asked questions about crossbites, as well as how orthodontists are trained to help.

What is a crossbite?

Your child’s upper teeth should all ideally sit in front of their bottom teeth. If a few top teeth are growing slightly behind their lower teeth, this is what an orthodontist would call a crossbite. There are two main types depending on which upper teeth are affected:

Posterior crossbite

This is when the back upper teeth are sitting inside the lower teeth. This crossbite may be on both sides (bilateral) or only one side (unilateral).  It can be harder to notice this type initially, as the teeth are further back in the mouth.

Anterior crossbite

If your child’s front upper teeth are sitting behind their lower ones, this is called an anterior crossbite.

Can I ignore my child’s crossbite?

Untreated crossbites can cause significant tooth, gum and jaw complications.  A crossbite with one or more front teeth can lead to loosening of the opposing tooth or teeth, gum recession and tooth wear.  A posterior crossbite can lead to uneven jaw growth, facial asymmetry and tooth wear.

Even if your child only has one tooth in crossbite, it is definitely worth seeking orthodontic treatment before any of these potential complications arise.

What does crossbite treatment look like?

Orthodontists are trained to diagnose and assess the severity of crossbites in children. They will discuss this with you and help you choose the right kind of treatment for your child’s circumstances.

There are many different treatment options and the choice will depend on the position and severity of the crossbite.  Your orthodontist may suggest a fixed or removable expander for a posterior crossbite, and either limited braces or a plate for an anterior crossbite.  Clear aligners can even be used in some instances.

Only a specialist orthodontist has the three years of additional training to advise and undertake the right treatment for your child.
