An underbite is a dentistry word that refers to a forward-protruding lower jaw. As a result, the lower jaw extends beyond the upper teeth. The severity of the underbite can range from minor to severe, with the lower jaw overlapping the upper jaw and the teeth failing to contact due to the large gap. More about gap in teeth.

What Causes an Underbite?

Normally, your teeth grow in such a way that the top teeth cover the lower teeth. The molars should be able to fit together. However, a person’s development of such a disease is caused by a number of variables. Here are a few examples:


If a member of your family has this ailment, you are more likely to have it as well. The person’s jaw, tooth form, and size are also determined by genetics.

As a result, some people are born with teeth that are unusually close together, impacted, do not grow all of their teeth (hypodontia), are irregularly shaped, overjet, or teeth that do not fit together.

Childhood Habits

Some childhood habits can contribute to the development of an underbite. These habits are:

  • thumb sucking (can also cause tongue thrust.)
  • Nail biting
  • Use of a pacifier by children over the age of three
  • Using the tongue to push the teeth
  • Long-term bottle-feeding
  • Poor oral hygiene practices (which also causes dental plaque and tooth decay)


Severe injuries to the jawbones may result in permanent damage. Although it is generally feasible to restore a fractured jawbone, the jaws usually do not fit properly even after surgical realignment.


Tumors in the jawbones or the mouth may cause the jaws to protrude, resulting in an underbite.

Types of Underbites

Underbites are classified into two categories.

Dental underbites Are a misalignment of the teeth that occurs when a crossbite forms in the front of the mouth rather than the sides. Although the teeth are somewhat forward, the lower jaw does not protrude.

Skeletal underbites occur through a malformation of the jawbone. It is usually genetic.

  • Speaking Difficulties
  • Difficulties chewing food
  • Malocclusion causes discomfort in the mouth and face.

The purpose is to enlarge the upper jaw, increase the dental arch, and shift the teeth within the bone. However, this is dependent on the pathology of the maxilla and mandible.

Tooth Extraction – Extraction of a tooth can alleviate crowding and allow for more natural biting.

Overbite Vs Underbite

When your mouth is closed, an overbite occurs when your upper teeth overlap the lower teeth excessively. When you have a smaller jaw or your lower jaw is shorter than your upper jaw, you are more likely to develop this problem.

When your mouth is closed, an underbite occurs when your lower jaw lies in front of your upper jaw. When you have this issue, you will commonly appear to have a projecting chin, however, in less severe cases, this may be more muted.
