Underbites can affect both your oral health and the appearance of your smile. Be assured, a Smile Generation-Trusted dentist can help.


What is an Underbite?


An underbite describes when the lower teeth and jaw extend beyond the upper teeth. Usually, the upper teeth partially conceal the lower teeth, but in an underbite, it's the opposite, with the lower teeth jutting out.

Underbite Corrections in Children and Adults


Treatment for malocclusion varies, depending on its severity. Sometimes, primary or permanent teeth require extraction to create space. Other times, jaw surgery for bone-related bite issues and the use of fixed or removable appliances might be necessary.



Braces, consisting of brackets and wires, are fixed appliances designed to reposition teeth.

Clear Aligners

Utilizing a sequence of plastic trays, clear aligners effectively correct underbites by gently guiding teeth into proper alignment without the need for braces.

90 percent of school-aged children have some degree of malocclusion, but only 10 to 15 percent require treatment.


These treatment options are designed to correct underbites by addressing issues with the jaws and teeth.


Complications That May Result From an Underbite

An underbite not only affects the mouth and face esthetically but also can cause other oral health issues depending on its severity. In serious cases, the lower teeth protrude significantly, while milder cases may go unnoticed. Beyond its cosmetic impact, an underbite can lead to difficulties in biting and chewing food, challenges with speaking, and discomfort in the mouth and face caused by jaw misalignment.


When Should You Fix an Underbite?

Optimal results are typically achieved when treating underbites during childhood and pre-teen years since the jaw is more adaptable while still growing. Although successful treatment is possible for adults, it could require underbite jaw surgery. The specific treatment required to correct an underbite depends on its severity and the underbite causes. Correcting an underbite has significant advantages. It simplifies teeth cleaning, reduces the risks of tooth decay and gum disease, and alleviates strain on teeth, jaws, and facial muscles. This, in turn, lowers the chances of tooth fractures and provides relief from painful temporomandibular disorders often associated with underbites.
