What is a under bite?

Underbite: For the layman, the easiest way to explain it is that when you bite down, your lower anterior teeth protrude and come in contact with the buccal (outside) surface of your maxillary teeth. This relationship can be skeletal in nature.

Class III: Upper teeth and/or jaw too far back, lower teeth and/or jaw too far forward, or both. A Class III malocclusion.

Underbite: It is the condition where the lower jaw and teeth are in front of the upper jaw and teeth.

Lower teeth : are in front of the upper teeth in an underbite. These types of bites tend to be hereditary. You should see an orthodontist as soon as an underbite is present ( as early as age 7) to see if treatment is needed at this time. Often early correction of an underbite will prevent the need for more extensive treatment ( like jaw surgery) later.

Lower teeth protrude: if you know that an overbite refers to protruding upper teeth, think the opposite. An underbite is when your lower teeth protrude in front of your upper teeth. It may be due to an alignment problem of your teeth or of your jaws or both.

Dental vs Skeletal: And under bite is defined when the upper front teeth bite "behind" the lower front teeth. This can be due to a skeletal discrepancy (upper jaw small compared to lower jaw or lower jaw large compared to upper jaw) or due to a dental issue. I recommend seeing an orthodontist and get complete ortho records for a proper diagnosis.

Common condition: It is a common orthodontic condition and fortunately, this condition is relatively easy to correct. If the underbite is severe, the corrective braces or even surgery may be required. See your orthodontist for evaluation, diagnosis and treatment.
