Can Invisalign Fix Crossbite?

 Dr. Kurtz | March 21, 2022

Crossbite is a common dental condition that can lead to complications if not treated. One of the most common treatments for this condition is Invisalign. In fact, there is some indication that Invisalign is more effective than traditional braces when it comes to crossbite.

Crossbite is a type of misalignment, or malocclusion, where your upper and lower teeth do not align properly. More specifically, some of the bottom teeth are outside of the top teeth with the jaw closed.

Causes of Crossbite

Most cases of crossbite are hereditary, that is the patient is born with a jaw that is too big or too small. However, a crossbite may be due to bad habits. Some of the most common causes of crossbite are as follows:

  • Cleft palate/lip
  • Thumb/pacifier sucking
  • Delayed eruption of secondary teeth
  • Losing baby teeth early/late
  • Mouth breathing
  • Small dental arch
  • Small upper or large lower jaw (also known as a skeletal crossbite)

If you do not treat crossbite, you may face a variety of problems, including damage to your teeth/gums and problems with your jaw. As mentioned, Invisalign clear aligners are highly effective for treating crossbite.

Invisalign Explained

Invisalign is a system of clear aligners that came onto the scene in the late 1990s. Since that time, it has been touted as a desirable, effective alternative to traditional braces. The transparent plastic aligners apply pressure to your teeth, gently shifting them to their appropriate position.

Here's how they work:

  • Step 1: consultation- usually free. At this time, the dentist will examine your mouth and do a digital scan of your teeth. This will help them design your personalized treatment plan
  • Step 2: the scans and information will be sent to the lab and a series of clear aligners will be made based on your current, as well as your anticipated, teeth alignment
  • Step 3: once your aligners come in, you'll be required to wear them for at least 22 hours a day. You should only remove them to eat, drink, or practice proper oral hygiene. You should see a shift of about 0.25 to 0.3 millimeters every 2 weeks
  • Step 4: after the first 2 weeks, you'll return for a follow-up appointment so the dentist can check your progress and give you the rest of your aligners
  • Step 5: you will switch your aligners to the next set every 2 weeks and follow-up appointments will be every 6 weeks
  • Step 6: once treatment has completed, you'll be required to wear a retainer while you sleep to keep your teeth straight

Some of the advantages that Invisalign has over traditional braces is that the aligners are comfortable, discrete, and convenient. Also, when it comes to correcting crossbite, Invisalign has another advantage: it covers the whole biting surface of the teeth.

The reason that Invisalign is effective at fixing crossbites is that it puts a separation between your upper and lower arches. Since the teeth are not touching, one tooth in the crossbite can't stand in the way of another one shifting. Therefore, the process is much easier and faster than it would be with traditional braces.

Traditional braces alone can't keep the teeth separate without fixed acrylic dental appliances or bite blocks- which are extremely uncomfortable.

Crossbites Invisalign Can Fix vs. Crossbites Invisalign Can't Fix

Invisalign can fix dental crossbites, which are caused by misaligned teeth. On the other hand, if your crossbite is due to skeletal irregularities, such as jaw issues, you will probably need traditional or lingual braces instead.

How Long Does Treatment Take?

For most patients, a crossbite can be fixed by Invisalign within 12 to 36 months. As with other treatments, the time varies based on the severity of the condition and how compliant the patient is with wearing the aligners.

Also, if you have multiple issues, such as a crossbite with overcrowded teeth, treatment time will be longer.

How Much Does Invisalign Cost?

At Invisalign Toronto, our packages start at $2,900. This includes all of your aligners, a retainer to wear following treatment, your initial consultation, and supervised treatment.

Advantages & Disadvantages of Invisalign for Crossbites

When you are determining your best course of treatment, it's a good idea to learn the advantages and disadvantages of each option. The advantages and disadvantages of Invisalign for fixing crossbite are:


  • Fully covers bite surface of teeth
  • Removable, so you can clean teeth
  • Discrete, convenient, and comfortable
  • No metal wires/brackets to cut your mouth
  • Easier to keep clean
  • Cost is comparable to traditional braces
  • May prevent bruxism
  • Causes less discomfort than traditional braces
  • Plastic is FDA approved for medical use


  • Removable- your compliance determines the outcome
  • May not work for severe crossbite
  • May be more expensive than other treatment options
  • Some discomfort compared with other treatment options

When Would Alternative Treatments be Required?

We know that Invisalign is effective for treating crossbite due to tooth misalignments, not for skeletal issues. If this is the cause of your crossbite, you will likely need alternative treatment.

It is important to note though, skeletal crossbites are easier to treat in children and teens because their jaws are still growing and can easily be redirected.

Alternative treatments include:

  • Traditional braces
  • Surgery

Is it Necessary to Fix a Crossbite?

While you may not feel that your crossbite is that serious, it is important to have it fixed because it can lead to severe complications. This is one of the more serious bite issues. Some of the complications it may lead to include:

  • Chipped/cracked/damaged teeth
  • Receding gums
  • Increased risk of gum disease
  • Increase risk of tooth decay
  • Pain when biting/chewing
  • TMJ issues
  • Headaches
  • Toothaches
