Crossbite
A crossbite occurs when one or more upper teeth bite inside the lower teeth instead of outside them. Crossbites can involve the front or back teeth and may reflect tooth position, arch width or jaw relationships.
Crossbites and open bites describe ways the upper and lower teeth do not meet in the expected relationship. The cause and timing determine how they are managed.
A crossbite occurs when one or more upper teeth bite inside the lower teeth instead of outside them. Crossbites can involve the front or back teeth and may reflect tooth position, arch width or jaw relationships.
An open bite exists when some opposing teeth do not contact when the jaws close. It can affect the front or back teeth and may be associated with eruption patterns, habits, tongue posture or jaw relationships.
Certain crossbites in growing children may be evaluated earlier because growth and arch development can influence treatment timing. An assessment does not automatically mean treatment should start immediately.
Braces, aligners, expansion, habit management, elastics or other approaches may be considered. More complex skeletal open bites can require a different treatment pathway.
