Crossbite is when one or more of the upper teeth on the front or sides of the mouth end up on the inside of the lower teeth. When detected early, a crossbite can be corrected. Crossbites can corrected by using braces, expanding the upper teeth or sometimes surgery. When a crossbite is detected, it should be corrected because many issues can arise such as misalignment, troubles chewing/eating, less confidence in smiling, and gum disease.
