A crossbite happens when one or more upper teeth sit inside the lower teeth instead of fitting slightly outside them. It can affect the front teeth (anterior crossbite), the back teeth (posterior crossbite), or both. Some people notice it because their teeth look uneven, while others experience jaw discomfort, uneven tooth wear, or difficulty chewing.
A crossbite is fixed with braces, Invisalign, palatal expanders, or jaw surgery, depending on the type and severity. Treatment depends on how severe the problem is, the age of the patient, and if the issue involves the teeth, the jaw, or both. In many cases, orthodontic treatment can correct a crossbite and improve how the teeth function together.
Signs You May Have a Crossbite
Not everyone realises they have a crossbite. Common signs include:
- Upper and lower teeth that do not line up properly when biting down
- One or more upper teeth sit behind the lower teeth
- Uneven or asymmetrical smile
- Jaw pain, clicking, or discomfort
- Difficulty chewing or biting evenly
- Noticeable tooth wear on certain teeth
A professional evaluation can confirm if a crossbite is present and determine the best course of treatment.
Crossbite Treatment Options
Several treatments can correct a crossbite. The best option depends on the type of crossbite, how advanced it is, and the underlying cause.
Braces
Traditional braces remain one of the most effective ways to correct a crossbite. They gradually move teeth into healthier positions and can address both mild and complex bite problems.
Braces are often recommended when multiple teeth need repositioning or when the bite requires significant correction.
Invisalign
Many crossbites can be treated with Invisalign. Clear aligners apply controlled pressure to move teeth gradually into better alignment without the look of traditional braces.
Invisalign is often a good option for mild to moderate crossbites, though some complex cases may need additional orthodontic appliances or a different approach.
Palatal Expanders
A narrow upper jaw is a common cause of posterior crossbite, particularly in children. A palatal expander gradually widens the upper jaw, creating enough space for the teeth to align properly.
Expanders work best before the jaw has fully matured, making early evaluation important for younger patients.
Jaw Surgery
Severe crossbites caused by significant jaw discrepancies may require orthognathic surgery. This treatment is typically reserved for adults whose jaw growth has finished and whose bite cannot be corrected with orthodontics alone.
Surgery is usually combined with braces or aligners to achieve proper alignment and long-term stability.
Can Invisalign Fix a Crossbite?
Yes, Invisalign can correct many types of crossbite. Modern clear aligners can move teeth in multiple directions, making them effective for many anterior and posterior crossbite cases.
The success of Invisalign depends on how complex the bite problem is. Mild to moderate crossbites often respond well to aligners, while severe skeletal crossbites may need additional orthodontic treatment or surgery. A consultation is the best way to find out if Invisalign is right for your case.
Crossbite Treatment for Children vs. Adults
Children
Early treatment is often simpler and more effective because the jaw is still developing. Palatal expanders work particularly well in children, and orthodontic correction can guide proper jaw growth before problems become more complex.
The American Association of Orthodontists recommends an orthodontic evaluation by age 7 to catch bite issues early.
Adults
Adults can correct a crossbite, even if they have had it for many years. Treatment may take longer because the jaw is no longer growing, but braces and Invisalign can still produce significant improvements.
In more severe cases involving jaw structure rather than tooth position alone, surgery may be recommended as part of the treatment plan.
What Happens If a Crossbite Is Not Treated?
A crossbite does not always cause immediate problems, but it can create issues over time:
- Uneven tooth wear from improper contact
- Gum recession around affected teeth
- Jaw strain, pain, or TMJ discomfort
- Facial asymmetry
- Difficulty chewing comfortably
- In children, the potential influence on jaw development
Early treatment is often simpler than correcting complications that develop later.
How Long Does Crossbite Treatment Take?
Treatment time varies based on severity and the method used:
Mild cases: 6 to 12 months
Moderate cases: 12 to 18 months
Complex cases: 18 to 24 months or longer
Your treatment plan will include a timeline based on your specific situation.
Cost of Crossbite Treatment
Crossbite treatment costs depend on the type of correction needed, how long treatment takes, and if surgery is involved. Braces and Invisalign typically range from $3,000 to $7,000. Palatal expanders may cost $1,000 to $3,000. Jaw surgery, when required, involves additional fees.
Many dental insurance plans cover a portion of orthodontic treatment. A consultation will give you a clearer picture of costs and payment options for your specific case.
FAQs
Can a crossbite be fixed without braces?
Some crossbites can be corrected with Invisalign or other orthodontic appliances. The best option depends on the type and severity of the bite problem.
Can Invisalign fix every crossbite?
No. Invisalign can treat many crossbites, but severe skeletal crossbites may need additional treatment or surgery.
Can adults fix a crossbite?
Yes. Adults can often correct a crossbite with braces, Invisalign, or, in some cases, jaw surgery.
Does a crossbite get worse with age?
It can. Uneven tooth wear, gum recession, and bite problems may become more noticeable over time if a crossbite is left untreated.
Is crossbite treatment painful?
Most patients experience mild discomfort when braces are adjusted or when switching to new aligners. This typically goes away within a few days.
At what age should a crossbite be treated?
Crossbites can be treated at any age, but early evaluation (by age 7) allows for simpler intervention while the jaw is still developing.
