Underbite occurs when the lower teeth protrude past the 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 upper incisors, missing lower teeth or a combination of all the above. Early correction of underbite is recommended.
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 orthodontically through growth modification of the jaws; extraction of teeth; and in some cases surgical correction of the jaws.
