What is a palatal expander?

 

If Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard and our team at Metro Orthodontic Specialists have recommended a palatal expander, you might be wondering what it is and how it will help you. A palatal expander is a small appliance fitted in your mouth to create a wider space in the upper jaw. It is often used when there is a problem with overcrowding of the teeth or when the upper and lower molars don’t fit together correctly. While it is most commonly used in children, some teens and adults may also need a palatal expander.

Reasons to get a palatal expander

There are several reasons you might need to get a palatal expander:

  • Insufficient room for permanent teeth currently erupting
  • Insufficient space for permanent teeth still developing which might need extraction in the future
  • A back crossbite with a narrow upper arch
  • A front crossbite with a narrow upper arch

How long will you need the palatal expander?

On average, patients have the palatal expander for four to seven months, although this is based on the individual and the amount of correction needed. Several months are needed to allow the bone to form and move to the desired width. It is not removable and must remain in the mouth for the entire time.

Does it prevent the necessity for braces?

The palatal expander doesn’t necessarily remove the need for braces in the future, but it can in some cases. Some people only need braces because of a crossbite or overcrowding of the teeth, which a palatal expander can help correct during childhood, when teeth are just beginning to erupt. However, others may eventually need braces if, once all their permanent teeth come in, they have grown in crookedly or with additional spaces between.
