Orthodontic Bite Problems

Crossbite

Crossbite can occur in the front and/or the sides of the mouth. One or more upper teeth may bite on the inside of the lower teeth. This can occur with a single tooth or multiple teeth. Early correction of crossbite is recommended.

Crossbite should be corrected right away because it can:

  • cause premature wear of the teeth
  • cause gum disease including bone loss
  • cause asymmetrical development of the jaws
  • cause serious problems with chewing patterns
  • make your smile less attractive

How can a crossbite be orthodontically corrected?

If there is a single tooth crossbite, the tooth can be moved with braces into the correct position. In some cases, a retainer can be utilized. With multiple teeth in crossbite, the arch needs to be expanded with braces or other specialized appliances.

Openbite

How can an openbite be orthodontically corrected?

Openbite can be corrected through growth modification of the jaws using braces, extrusion of the front teeth and in some cases, surgical correction of the jaws. Also breaking oral habits, such as finger sucking, will facilitate the correction of an openbite.

Overbite

Class II Overbite

Overbite side view illustrationExcessive overbite occurs when the upper front teeth protrude over the lower front teeth. Generally there is no contact between the upper and lower front teeth. Often you cannot see the lower incisors. Overbite is due to an excess amount of eruption of front teeth or over development of the bone that supports the teeth and a front to back discrepancy in the growth of the upper or lower jaw (Class II Relationship). Excessive overbite is also known as a deep bite.

Excessive overbite should be corrected because it can:

  • cause improper functioning of your front teeth
  • result in the lower front teeth biting into the gum tissue of the upper palate leading to problems
  • unusual wear of the lower front teeth
  • cause jaw or joint problems
  • make your smile less attractive

How can an overbite be orthodontically corrected?

Overbite can be corrected through moving the front teeth up and/or bringing the back teeth together, which will “open” the bite so the teeth are properly aligned and the deep bite is eliminated.

Overjet

Class II Overjet

Overjet side view illustrationExcessive overjet is also known as protrusion. In this case, the lower teeth are too far behind the upper front teeth. This can be caused by an improper alignment of the molars (Class II Relationship), a skeletal imbalance of the upper and lower jaw; flared upper incisors, missing lower teeth or a combination of all the above. In addition, oral habits such as thumb sucking, finger sucking or tongue thrusting can worsen the condition.

Excessive overjet should be corrected because it can:

  • prevent proper functioning of the front teeth
  • cause premature tooth wear
  • make your smile less attractive

How can overjet be orthodontically corrected?

Overjet can be corrected through growth modification using specialized growth appliances and/or elastics to reduce the skeletal imbalance or extraction of teeth.

Underbite

Class III Underbite

Underbite side view illustrationThe lower teeth protrude past the upper front teeth. An underbite is usually caused by undergrowth of the upper jaw, overgrowth of the lower jaw, or a combination of the two (Class III Relationship). Underbite can also be caused by flared lower incisors, missing upper teeth or a combination of all the above. Early correction of underbite is very important.

Underbite should be corrected because it can:

  • prevent proper functioning of the front teeth or molars which can lead to premature wear of the teeth
  • cause chewing or eating problems
  • cause jaw or joint problems
  • make your smile less attractive

Underbite can be corrected through growth modification of the jaws, extraction of teeth and in some cases, surgical correction of the jaws.
