Crossbite

A crossbite is a common dental misalignment where some upper teeth bite on the inside of the lower teeth, or the other way around. While it may seem like a minor issue at first, if left untreated, a crossbite can lead to jaw discomfort, uneven tooth wear, gum recession, and even jaw growth complications over time.

There are several types of crossbite, including anterior crossbite (in the front teeth) and posterior crossbite (in the back teeth), and both can affect one or multiple teeth on one or both sides of the mouth. The good news is that with modern orthodontic treatments, crossbites can be effectively diagnosed and corrected, often without surgery.

How to Fix a Crossbite

Treating a crossbite depends on the severity, the patient’s age, and the underlying cause. Early intervention is always beneficial, especially for children and teens with developing permanent teeth and jawbones. However, adults with crossbites can also achieve excellent results using modern solutions like clear aligners for crossbite treatment.

Treatment Options

There are a variety of ways to treat a crossbite:

  • Palatal expanders: These devices widen the upper jaw, especially helpful in children and teens with growing bones.
  • Braces: Traditional braces apply continuous pressure to guide the teeth and jaw into correct alignment.
  • Jaw surgery: In severe or skeletal cases, jaw surgery may be needed to properly position the upper and lower jaws.
  • Clear aligners: These use a series of custom trays to gradually move teeth and correct mild to moderate crossbites.

Clear Aligners for Crossbite

One of the most asked questions is, “Can clear aligners fix a crossbite?” The answer is yes for many cases, particularly dental crossbites caused by misaligned teeth rather than skeletal structure, clear aligners for crossbite are an excellent choice.

How They Work

Aligners for crossbite work by applying gentle, targeted pressure to reposition the teeth over time. Unlike braces, these aligners are:

  • Nearly invisible
  • Removable
  • Comfortable to wear

At OrthoFX, our aligners are engineered with advanced polymers to deliver optimal comfort and movement.

Can Invisible Aligners Fix a Crossbite?

Yes. Our invisible aligners for crossbite are specifically designed for mild to moderate types of crossbite, such as:

  • Anterior crossbite (affecting the front teeth)
  • Posterior crossbite (affecting the back teeth)
  • Single tooth crossbite (just one tooth out of alignment)

OrthoFX aligners are custom-designed for each patient, using 3D scanning and AI-assisted mapping to ensure the best possible outcome.

Crossbite Symptoms: What to Watch For

Here are some crossbite symptoms to watch out for:

  • Uneven or misaligned bite
  • Pain or tension in the jaw
  • Clicking or shifting when chewing
  • Difficulty biting or chewing certain foods
  • Excessive wear on certain teeth
  • Frequent headaches or neck tension

If you're experiencing any of these, it may be time to have your bite evaluated by an orthodontic professional.

What Causes a Crossbite?

Several factors can contribute to a crossbite, including:

  • Genetics and inherited jaw structure
  • Thumb sucking or tongue thrusting during childhood
  • Delayed or abnormal loss of baby teeth
  • Abnormal eruption of adult teeth
  • Prolonged use of pacifiers or bottle-feeding
  • Breathing through the mouth instead of the nose, which can affect how the jaw develops

In some cases, crossbite corrected at a younger age prevents future complications that could require more invasive procedures later.

Crossbite Treatment: What to Expect

At OrthoFX, your treatment journey starts with a 3D scan of your teeth and bite. From there:

  • Your doctor creates a customized treatment plan.
  • You'll receive a series of clear aligners specifically designed to reposition your teeth.
  • You’ll check in periodically, virtually or in-person, to track progress.
  • You will be provided with a retainer post-treatment to maintain results.

How Long Does Crossbite Treatment Take?

Treatment duration varies based on:

  • Type and severity of the crossbite
  • Your age and jaw development
  • Whether you wear the aligners as prescribed by your doctor

Most mild cases treated with OrthoFX aligners can be completed within 6 to 18 months. Severe cases may require longer treatment or a combination of aligners and other orthodontic treatments.
