An Underbite occurs when the lower teeth overlap the upper teeth. This condition is also called a Class III malocclusion or prognathism. It can cause you to have a bulldog-like appearance. An Underbite can cause a number of issues, including difficulty eating, chewing and speaking properly, chronic jaw pain or TMJD, tooth decay, chronic mouth breathing, and sleep apnea or other airway difficulties.
Underbites are often treated with a palatial expander or a reverse-pull face mask. Additional methods, such as IPR or extractions are sometimes also done. In severe cases, jaw surgery may be necessary to correct the problem.
