Expanders

A rapid maxillary expansion appliance (RME), 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 RME to correct minor crowding problems.

Why do I need this?

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.

What to expect

Usually there is no discomfort with these appliances but if slight pain occurs try a mild pain reliever as a temporary measure. (Adult supervision always required)

undefinedYou will probably notice a separation of the front teeth as the expander starts to work. This usually closes naturally when the expansion is finished.

Speech may also be affected.

How long does this take?

The expansion is generally not a very long process. It is important to hold the expanded area open for 9-12 months to allow the new bone to fill the gap and ensure the widening won't close up again.
