Everything you should know about Underbite

An underbite is a dental word that refers to a forward-protruding lower jaw. As a result, the lower jaw extends beyond the top teeth. The degree of the underbite varies from a moderate instance in which the lower jaw overlaps the upper jaw to a severe condition in which the teeth do not contact due to the gap in teeth.

What Causes an Underbite?

Generally, your teeth develop in such a manner that the upper teeth fit comfortably over the lower teeth. Molars should fit snugly together. Numerous variables, however, contribute to the development of such a disorder. Several of them are listed below: Generally, your teeth develop in such a manner that the upper teeth fit comfortably over the lower teeth. Molars should fit snugly together.

If you have a family member who also has this ailment, you are more likely to get it. Additionally, genetics determine a person’s jaw form, tooth shape, and size.

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

Childhood Habits

Certain childhood behaviors may have a role in the development of an underbite. These behaviors include the following:

  • Thumb sucking (can also cause tongue thrust.)
  • Nail biting
  • Use of a pacifier by children over the age of three
  • Pushing of the teeth using the tongue
  • 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. While it is frequently possible to repair a broken jawbone, even after surgical realignment, the jaws frequently do not fit properly.


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

Types of Underbites

Underbites are classified into two types.

Dental underbites are a type of tooth misalignment that occurs when a crossbite manifests itself in the front of the mouth rather than the sides. Although the teeth protrude slightly forward, the lower jaw does not protrude.

Skeletal underbites happen as a result of a jawbone malformation. Generally, it is hereditary.

What Issues Does an Underbite Cause?

An underbite is more than simply an aesthetic concern. According to the American Dental Association (ADA), the more serious this issue is, the more likely it is to create oral health concerns such as the following:

  • Difficulty in chewing the food
  • Challenges with speaking
  • Pain in the mouth and face as a result of malocclusion.
  • Sleep apnea
  • Tooth enamel wear that is excessive
  • Chronic mouth breathing and bad breath
  • Prognathism

Additionally, when you have a prominent underbite, your confidence will suffer. More about Lingual treatment.

How to Treat an Underbite

It is rather usual for teeth to be somewhat out of alignment once the majority of the permanent teeth when tooth eruption takes place. However, in some cases, the underbite is severe enough that treatment has a greater effect on the patient. Clinical medicine won’t be able to treat this condition alone so, allow Taft Hill Orthodontics to assist you in resolving your underbite issues.

Below are some of those benefits:

  • Your teeth are easy to clean
  • Avoids the risk of diseases of the gums.
  • There will be less tension on the jaws, teeth, and face muscles as a result.
  • Reduce the risk of developing a dental abscess.
  • It reduces the risk of breaking a tooth or tooth loss
  • Reduces the likelihood of having temporomandibular joint disorder

This issue can only be treated by having it aligned by a specialist. In order to correct this condition, an orthodontist is required. Dr. Timothy C. Hardy can correct your underbite by the use of any of the following procedures:

Braces – It is the most often used orthodontic treatment method for underbite correction. Dental braces are not discrete and may be apparent while speaking or smiling. This is addressed by clear aligners.

Appliances – Certain appliances are effective in treating this condition. These are made to fit your mouth precisely and can occasionally be uncomfortable due to their greater visibility than braces. When necessary, orthodontists will recommend this therapy.

The reverse full facemask is an example of an orthodontic device. This item is comparable to orthodontic headgear that is worn around the head. To correct an underbite with this approach, metal bands are attached to the upper back teeth, allowing the device to gently pull the upper jaw into perfect alignment.

The upper jaw expander is another form of the dental device. The upper jaw expander is a screw-in device that fits over the upper jaw’s rear teeth. The objective is to increase the width of the upper jaw, expand the dental arch, and reposition the teeth within the bone. This, however, is dependent on the pathology of the maxilla and mandible.

Tooth Extraction – Tooth extraction can help get of crowding so that biting can come together more naturally.

Surgery – This should only be used as a last resort if the orthodontist believes that all other options have failed. It occurs seldom, since surgery is often not required to correct an underbite.

Orthognathic surgery is a kind of jaw surgery. This form of surgery is very customized and entails splitting your jawbones and making customized adjustments to your jaw alignment.

If you have cleft lip and palate, you may need surgery prior to addressing your underbite.

Overbite Vs Underbite

When your mouth is closed, an overbite occurs when your top teeth overlap your bottom teeth excessively. This issue is most often associated with a smaller jaw or a shorter lower jaw than an upper jaw.

When your mouth is closed, an underbite occurs when your lower jaw lies in front of your upper jaw. When you have this condition, you frequently have the appearance of a protruding chin, though this may be more subdued in less severe cases. Schedule an appointment.
