An underbite occurs when your lower teeth close over the top of your upper teeth. Underbites can cause difficulty chewing and speaking.

Caused by a misalignment of the jaw, an underbite can be corrected with a range of treatments to improve your comfort and appearance.

So how do I know if I need treatment for an underbite?

Clinically referred to as a Class III Malocclusion, an underbite occurs when the bottom teeth noticeably protrude beyond the upper teeth.

What causes an underbite?

If one of your parents or grandparents had an underbite, there is a much larger chance that you will, too. In addition, certain ethnic groups are more likely to develop underbites, including those of Asian descent.

A famous example of the  genetic nature of this trait is the “Habsburg jaw.” Many generations of the royal Habsburg family in Europe were known for their distinctive protruding lower jaws, which are believed to have been the result of an underbite.

What do I do if I suspect I have an underbite?

In most cases, an underbite is easy to identify with a simple visual exam. However, your dentist or orthodontist will likely perform a complete evaluation of your teeth and jaw to determine the severity of your condition.

During the appointment, your dentist may take x-rays, photographs, and impressions to examine the specific relationship between your teeth, jaws, and head.

Is there any way to prevent an underbite  from forming?

Parents of young children can help their child’s jaw form properly by limiting their pacifier and bottle use.  Speak to your doctor or a dentist about the best time to begin this process.

If you notice your child snores or breathes through their mouth, you may be able to prevent issues in jaw development by treating these concerns early.

Is it really that important to get my underbite fixed?

The most commonly used treatment for underbites and other bite issues is orthodontics. Metal braces can adjust the position of teeth and improve jaw alignment to address an underbite.

Are there other options?

For minor underbites, clear aligners, such as Invisalign®, can provide results.

Devices, such as expanders, retainers, or headgear, may be used to treat an underbite.

Severe underbites may require surgery. However, jaw surgery is typically only performed as a last resort.

How do I plan my underbite treatment?

Depending on the severity, an underbite can have a serious impact on your oral health and quality of life . Scheduling an appointment with a doctor is the best way to find out whether you need treatment.
