At Quantum Orthodontics, the 3 Way expander is just one of the expansion appliances we use in order to make room for teeth and improve breathing. This can be done at an early age while the jaw and facial structure is still forming. The expander is custom made and Dr. Barb checks on the results in office. It is easy to wear and manage as it is removable, gentle, and not bulky. It works beautifully at developing the upper arch in three directions, and can replace other more conspicuous appliances. We try whenever possible to “grow the mouth to fit the teeth”. When we grow the mouth, we also can improve breathing which can provide more oxygen to the developing brain, improving sleep and school performance as a result.
