What Orthodontic Issues Can and Can’t Invisalign Fix?

Invisalign can fix the following issues in some patients, depending on the severity or if there are a combination of issues:


Can Invisalign fix an overbite? In some cases, Invisalign can move teeth so that the top and bottom teeth align properly when your mouth is closed.

Crooked Teeth

Invisalign is a comfy and effective treatment option if you are looking to straighten your smile.


Invisalign can treat an underbite by moving the lower teeth back, so they naturally sit behind the front teeth.

Gaps in Teeth

Invisalign can close the gaps between teeth to create a healthier mouth and a pleasing smile. However, there is a limit to the amount of space that needs to be closed.

Crowded Teeth

Invisalign can also fix crowded teeth, depending on the severity and complexity of the problem.

The above list is just a precise one; in reality, there are many dental problems that Invisalign treat alone or in combination with other treatments.

Limitations of Invisalign

Here are some cases where Invisalign may not work as effectively as braces:

Tooth Shape

Some patients have teeth that are not ideal for fitting inside the aligner. Round, short, or pegged teeth may not allow the aligner to firmly grip. Therefore, Invisalign isn’t effective at moving your teeth into the desired position.

Large Gaps Between Teeth

If a patient would like to close a gap between two teeth or several gaps, aligners can close no more than 6mm of space per arch (top teeth or lower teeth).

Tooth Position

In an overcrowded mouth, a tooth may rotate to fit. If the rotation is more than 20 degrees for molars, Invisalign cannot move them into the desired position.

Midline Movements

Some patients have front teeth that do not match their midline. Invisalign can correct a midline discrepancy by 2mm to the left or right per arch, but a space larger than that needs to be treated with braces.
