Dr. Tal Jergensen, Dr. Scott Hope and Dr. Samuel Waddoups may recommend a palatal expander if you have narrow dental arches. Palatal expanders help to widen your dental arches so that your teeth can move into their correct positions without difficulty. To learn more about palatal expanders in Temecula, Hemet, Murrieta and Corona, California, and to schedule an appointment with one of our orthodontists, call our Miles of Smiles office today.
