An orthodontic facemask, also called a reverse-pull headgear, is an external device used to correct an underbite by pulling the upper jaw forward
How It Works: External frame: A vertical metal bar rests in front of your face with soft pads touching your forehead and chin.Inside connection: Rubber bands hook from the metal face bar to an appliance inside your mouth, like a palatal expander or braces.Gentle pulling: The elastics apply steady forward pressure to help the upper jaw grow and line up properly with the lower jaw.
