A deep bite is a type of dental condition that occurs when the upper front teeth overlap the lower front teeth too vertically when biting down. This can cause the lower front teeth to bite into the roof of the mouth and the upper front teeth to bite into the gums behind the lower front teeth. A deep bite can be caused by a variety of factors, including genetics, excessive wear of the teeth, and oral habits such as thumb-sucking and tongue-thrusting. It can cause problems with chewing, and speaking, and can put extra pressure on the teeth and jaw joints. It can also cause the lower front teeth to become loose or worn down over time. Often times we recommend against ceramic braces commonly known as "clear braces" on the lower teeth, as the brackets can promote wear on the upper teeth with this type of bite.
