What is overbite?It is a condition in which the bite is so deep that the lower teeth are not visible when chewing.

In dentistry, it is sometimes referred to as an "overbite" or "low bite". Along with bucktooth and passive mouth, it is the most common type of malocclusion.

If bucktooth and passive mouth refer to anterior-posterior problems in the upper and lower jaws, overbite refers to vertical problems in the upper and lower jaws.

Overbite is also a symptom that can be seen with bucktooth, passive mouth, plexus with overlapping teeth, and bucktooth.

Overbite can cause the following problems

  • Prone to TMJ disorder
  • Upper front teeth are easily damaged.
  • Lower front teeth easily damage the gums behind the upper front teeth.
  • Prone to tooth erosion
  • Artificial teeth are fragile.
  • Prone to bucktooth
  • Prone to gummy smiles

It is advisable to cure an overbite because these are also related to the longevity of the teeth.

Prone to TMJ disorder

In an overbite, the bite is low and the lower jaw is covered by the upper jaw, limiting jaw movement when chewing or clenching.

And so on,This can put stress on the jaw joints and cause TMJ disorder.

When it comes to TMJ disorder,

  • Clicking sound when closing and opening the mouth
  • TMJ locks up and prevents the mouth from opening.
  • Pain when opening mouth

This can cause a variety of problems, such as

Upper front teeth are easily damaged.

If the lower front teeth push up against the upper front teeth in an overbite, the chewing force is chronically stronger on the upper front teeth,Inflammation of the tooth nerve and the gums and bone around the tooth may occur.

Inflammation of the gums and bone caused by biting is called "bite trauma," and if the condition worsens, there is a risk that the nerves in the teeth will die or the bone supporting the teeth will disappear, causing the front teeth to wobble and move.

Lower front teeth easily damage the gums behind the upper front teeth.

If the overbite is so severe that the lower front teeth attach to the back of the upper front teeth when chewing,The lower front teeth can damage the gums behind the upper front teeth.

Prone to tooth erosion

Because the teeth are easily subjected to forces from grinding and clenching,Teeth may be ground down.

The grinding of teeth by biting is called "occlusal wear," which may induce sensitivity or, worse, crack the teeth.

Artificial teeth are fragile.

The overbite is due to the force of the bite,Artificial teeth such as fillings, coverings, implants, and bridges tend to break easily.

Prone to bucktooth

To push up the upper front teeth with the lower front teeth,The upper front teeth tend to tilt outward.

When the upper front teeth tilt outward, they become bucktooth.

Since back teeth bite wear also occurs with age-related changes, the bite basically becomes lower and the overbite more severe as the years go by.

Then, even if the teeth are not bucktooth in youth, they may become bucktooth-like with age.

Prone to gummy smiles

In an overbite, the upper teeth are deeply covered by the lower teeth, making the gums easily visible when smiling,May be prone to gummy smiles.

There are many causes of overbite, including the size of the upper and lower jaws due to heredity and development, the height of the back teeth, and the habit of biting the lower lip.
