What Is Crossbite?

Crossbite is a form of dental malocclusion (also known as an imperfect positioning of the teeth, or a dental problem) in which one or more teeth have a more buccal or lingual position than does the corresponding tooth in the top or bottom dental arch. Simply put, in order to be diagnosed as having a crossbite, at least one your teeth must be closer to your cheek or to your tongue than is the tooth opposite it.

What Are the Causes of Crossbite?

There are a number of different reasons that a person can develop crossbite. One such cause of this dental malocclusion can be the misalignment of both the upper and the lower jaw. This misalignment of the jaws can cause one or more of your upper teeth to bite onto the insides of your lower teeth, creating a crossbite.

Another possible cause of the occurrence of a crossbite could simply be genetics. Many cases of crossbite are simply hereditary.

Some cases of crossbite are caused by a delayed loss of the baby teeth. Some individuals keep their baby teeth so long that the bigger, permanent teeth begin to grow behind the baby teeth, like a second row of teeth. These adult teeth often grow in improperly, and end up resulting in a crossbite. Prolonged thumb sucking is also thought to be a cause of some cases of crossbite- by sucking your thumb for years, you can succeed in deforming the upper bone of the palate and encouraging crossbite to occur.

In some cases, though very rare, the presence of certain types of mouth breathing can cause defects in the shape of the upper jaw, which in turn can affect tooth alignment. This is especially seen in children’s cases, in which a child has tonsils that are uncomfortably large, and force the child to breathe constantly and solely through their mouth instead of through their nose. When a person breathes through his nose, the tongue is positioned on the roof of the mouth, which contributes to lateral, healthy growth of the jaw. If a child breathes through the mouth, this forces the tongue out of position and away from the roof of the mouth. If this breathing pattern continues for a long enough span of time, it can cause the jaw to grow improperly and asymmetrically, encouraging the development of crossbite.

How is Crossbite Diagnosed?

Crossbite can be diagnosed by your dentist in Singapore. The dentist will examine the patient’s mouth, and identifies whether or not there is an incongruent positioning of corresponding teeth. The dentist will most likely examine your teeth, then ask you to bite down, so that he or she may aptly gauge the alignment of your teeth.

How Does Crossbite Affect a Patient?

Patients with a crossbite can experience painful chewing, headaches, and inflammation of the jaw joint which can cause chronic mouth and jaw pain. In very serious cases, the presence of a crossbite can cause the development of arthritis within the jaw joints, leading to degeneration of the joint itself. In less serious cases, crossbite can cause tooth loss and gingivitis, due to the misalignment of the teeth.
