A rapid maxillary expansion appliance (RMEA), also known as a rapid palatal expander, is used to widen the narrow upper jaw so that the upper and lower teeth will fit together better. The use of an expander is most common in children. We often use brackets (braces) on the upper front teeth in conjunction with the RMEA to correct minor crowding problems.
The Quad helix is an appliance designed also to widen your jaws to create room for alignment of your crowded teeth. It is attached to your molars by two bands and has four active helix springs that widen the arch of your mouth
Some people have an upper jaw that is narrow when compared to their lower jaw. This can result in a less than ideal bite and in some cases the lower jaw has to be swung to one side in order to produce better contact of the teeth.
It is possible and easy to widen the upper jaw while it is developing. This is a painless process. At a young age the upper jaw doesn’t have bone between it as some natural growth in this area occurs. As the jaw is expanded new bone grows within the widened area and the upper jaw remains permanently wider.
