Orthodontics
A palatal expander is an appliance placed in the roof of the mouth to widen the upper dental arch, which allows the arch to be painlessly separated and spread. A treatment used for younger patients. Many times a palatal expander can be used to create a proper alignment of the arches so permanent teeth have room to erupt in a natural position. Often, the use of an arch expander early may eliminate the need for braces later.
