Can Invisalign Fix an Overjet?

3 Mar 2020 by  admin in Invisalign

There is a natural space between the upper and lower teeth at the front of the mouth. Normally, this space is only big enough to let the front upper teeth rest comfortably on the front bottom teeth.

Some people have a larger space between their upper and lower front teeth. This condition is referred to as an overjet. Often caused by crowded teeth or thumb sucking, overjet bites can easily be fixed by Invisalign or other orthodontic treatments.

Overjet Vs. Overbite

Though commonly confused, there is an important difference between an overjet and an overbite. An overjet is a horizontal misalignment between the upper and lower front teeth. Normal alignment means that the upper front teeth and the lower front teeth are separated by about 2 millimeters. In an overjet, that separation is more than 2 millimeters.

An overbite, on the other hand, is the vertical misalignment between the upper and lower front teeth. The upper front teeth usually cover 25% of the lower front teeth, but in an overbite, the overlap is much greater.

Luckily, both an overjet and an overbite can be treated with Invisalign.

Do I Have an Overjet?

Those who have excessive overjet will most likely experience discomfort or lack of confidence in their smile. They might also notice:

  • Difficulty chewing or biting
  • Speech issues
  • Discomfort when eating
  • Irregular facial appearance

Though an overjet is not normally a serious condition, it can lead to complications if left untreated including:

  • Speech impediment
  • Poor sleep quality
  • Irregular jawline
  • Temporomandibular joint dysfunction (TMJ)

Treating an Overjet

There are a few treatment options for an overjet, with the most common and successful being retainers, and braces including metal and ceramic braces.

One of the most popular overjet treatments is Invisalign. It is an orthodontic system that uses clear plastic aligners to gently move teeth into a new position—similar to traditional braces. However, unlike traditional braces, Invisalign is clear and removable. They are unnoticeable when in place, and patients can take them out when eating or drinking.

Invisalign overjet treatments can be completed in as little as 8 months, but most people will need 12 to 16 months. However, the length of treatment time will vary depending on the overjet severity– and how often the patient wears the aligners. It’s recommended that patients wear them 20 to 22 hours every day, making it easy to remove them for eating, drinking, or special occasions.
