A crossbite is where an upper tooth has moved inwards.
There are two types of crossbites: 1. a crossbite at the front (anterior crossbite) where an upper front tooth has moved behind the lower front teeth; and 2. a crossbite at the back (posterior crossbite) where the back teeth sit inside the bite due to a constricted upper jaw.
Crossbites can cause poor appearance, wear and damage of the teeth, and difficulty chewing.
Don't worry, treatment is easy! Anterior crossbite are fixed with a simple plate, and posterior crossbites are best treated with an expander and braces.
