Crossbite

A crossbite happens when the upper teeth bite inside the lower teeth on one or both sides. Orthodontic treatment such as clear aligners or braces can guide the bite into a healthier position depending on the cause and severity.

Signs your bite may have a crossbite
Upper teeth sit inside the lower teeth when biting
Your bite feels uneven when chewing
The bite slides to one side to find a comfortable fit
Teeth on one side appear to meet differently than the other
What a crossbite usually means

In a balanced bite, the upper teeth normally sit slightly outside the lower teeth. With a crossbite, this relationship reverses in one area so the upper teeth bite inside the lower teeth.

Crossbites can affect a single tooth or a wider section of the bite. In some cases the bite may shift slightly to one side so the teeth can meet more comfortably.

Common causes

Jaw width differences: the upper jaw may be narrower than the lower.

Tooth position: individual teeth may tip inward or outward.

Bite shifting: teeth may move to find stable contact.

Changes after treatment: bite relationships may drift without retainers.

Conditions often related to crossbite

Crossbites sometimes appear alongside other bite or spacing patterns. Understanding the full bite helps orthodontists choose the most suitable treatment.

Overbite

Upper teeth overlap the lower teeth more than usual.

Underbite

Lower teeth sit in front of the upper teeth.

Crowded teeth

Crowding can influence how the bite fits together.

Open bite

Front teeth do not meet when biting together.

What usually helps

Treatment aims to guide the bite into a healthier relationship so chewing forces are shared more evenly. Orthodontists may recommend braces or aligners depending on the type of crossbite.

Clear aligners: sometimes suitable when the crossbite is caused mainly by tooth position.
Braces: often used when more bite control or broader movement is required.
Understanding Crossbite

How Crossbite Is Usually Corrected

Orthodontic treatment begins by understanding the bite relationship and which teeth are involved.

Once the bite pattern is clear, orthodontists guide the teeth into a more balanced position using braces or aligners.

Assess the bite relationship
Orthodontists identify which teeth sit inside the bite.
Choose the right treatment
Braces or aligners may be recommended depending on the crossbite type.
Gradually adjust the bite
Teeth move slowly into a healthier relationship.
Maintain the correction
Retainers help keep the new bite stable.
