Does Invisalign Fix Overbite?

An overbite is one of the most common reasons people seek orthodontic treatment but the word gets used loosely. Some people mean their upper front teeth stick out too far. Others mean their upper teeth cover too much of their lower teeth vertically.

Before asking whether Invisalign can fix yours, it helps to understand whether or which type of overbite you have.

The Two Types of Overbite

Dental overbite

A dental overbite happens when the teeth themselves are positioned incorrectly. The jaw sits in a normal position, but the upper front teeth protrude or the bite depth is too deep because of how the teeth have erupted or shifted over time.

Invisalign can treat dental overbites effectively in mild to moderate cases.

Skeletal overbite

A skeletal overbite is a structural issue involving the jaw bones themselves. The upper jaw protrudes relative to the lower, or the lower jaw is underdeveloped.

Clear aligners can only move teeth, but cannot reposition jaw bones. In this case, the person typically requires orthognathic surgery, sometimes combined with orthodontic treatment before and after the procedure, to achieve a stable correction.

How Does Invisalign Correct an Overbite?

Invisalign corrects dental overbites by moving the upper and lower teeth into better alignment over a series of custom aligner trays.

Small tooth-coloured attachments bonded to specific teeth give the aligners additional grip and allow for more precise movements that a plain tray couldn't achieve on its own.

For eligible patients, Invisalign also offers mandibular advancement features built into the aligner design. These features apply gentle forward pressure to the lower jaw during treatment, helping to correct deeper bites in growing patients and select adult cases.

Overbite Severity — Is Your Case Treatable with Invisalign?

Overbites are measured as a percentage of overlap. A normal overbite sits between 10 and 20 percent. Anything beyond that is considered excessive, and the degree of excess determines how complex treatment becomes.

Severe overbite cases may require a combined approach or fall outside what Invisalign can reliably correct alone. Work with a Toronto dental clinic that conducts 3D digital imaging to determine eligibility.

When Invisalign Is Not the Right Fit

• Severe skeletal overbites where the jaw bones themselves are misaligned
• Cases requiring surgical jaw repositioning (orthognathic surgery)
• Active tooth decay or untreated cavities, but they can be resolved before starting Invisalign
• Active gum disease or significant bone loss around the teeth
• Missing teeth that haven't been addressed, as gaps affect how aligners fit and function
• Patients with significant existing dental work like crowns or bridges on multiple teeth, as this limits how aligners can grip and move teeth
• Patients who cannot commit to 20 to 22 hours of daily wear

How long does it take for verbite correction with Invisalign?

Mild corrections can take as little as 6 to 12 months. More involved cases typically run between 12 and 24 months.

Can adults fix an overbite with Invisalign?

Yes. Adults are actually strong candidates for Invisalign overbite correction, provided the overbite is dental rather than skeletal in nature. Adults also tend to follow the time requirements better.

Does fixing an overbite change the shape of your face?

It can, subtly. Correcting a deep bite or a protruding upper jaw position often improves the profile and the relationship between the lips and chin. The changes are typically natural-looking rather than dramatic, and most patients consider them a welcome side effect of treatment.
