Palatal expansion

A palatal expansion is the use of an appliance placed in the mouth to make a constricted palate more wide. The following video summarizes the procedure.

A narrow palate usually allows less space for upper teeth, causing malocclusion, which is a bad relationship between teeth that gives them a misaligned appearance. Malocclusion also makes it hard to eat and brush your teeth, provoking malnutrition and other dental problems.

It is possible to expand the palate of children, teenagers, and sometimes young adults. There are many types of expanding appliances, but each usually covers the palate and holds on the upper teeth. Activation needs to be done with the expansion screw that is found in the middle of the appliance. The whole process can take several months to a year.
