Everything You Need to Know About Palatal Expanders
When correcting a misaligned bite, Dr. Feil has the training and experience to give you comfortable treatments and outstanding results. He accomplishes this using a variety of orthodontic appliances, including palatal expanders. This important tool helps prevent or eliminate more severe jaw and teeth problems that may not leave enough room for permanent teeth to grow correctly.
At Feil Orthodontics, we believe that everyone deserves healthy, beautiful smiles! We’re committed to giving you and your family a lifetime of healthy smiles in Bismarck, Dickinson, Mandan, and Beulah. Let’s take a closer look at what palatal expanders are, how they work, and what they can do to improve your child’s smile!
What is a palatal expander?
A palatal expander is a device that works with the natural changes that occur as the teeth and jaw develop to create more space in a child’s mouth by gradually widening the upper jaw. This may sound a little scary, but the upper jaw develops as two separate halves that don’t entirely fuse until after puberty. Each half can be gently separated and stabilized with a palatal expander until that happens. This treatment is time-sensitive because expanders work with the teeth and jaw as they grow.
Palatal expanders have two pieces that connect in the middle with a screw and are customized to fit over a few top teeth in the back of a child’s mouth. You activate the device by turning the screw in tiny increments each day with a small key. This creates tension at the junction of the two palatal bones, gradually moving them apart. Once we reach the desired expansion, Dr. Feil will keep the appliance in place for a few more months so the new bone can form in the gap and stabilize the expansion. Children typically wear palatal expanders for about six months in total.
Who can benefit from palatal expanders?
Permanent teeth usually replace children’s baby teeth between 6 and 13. Some children’s jaws are too small to accommodate their adult teeth, leading to crowded teeth and misalignment. Palatal expanders can:
- Reduce or eliminate overcrowding—expanders create space for all of a child’s upper teeth to erupt in the correct positions
- Reduce the risk of developing impacted teeth—when other teeth block an unerupted tooth, we can create room for it to emerge by widening the upper jaw
- And correct a crossbite—the upper teeth should close around the outside of the lower teeth, but a narrow palate can cause the upper teeth to bite inside the lower teeth. An expander can correct this before serious asymmetrical jaw growth, restoring facial symmetry.
Expanding the upper jaw with a palatal expander can also improve a child’s smile aesthetically, limit tooth extraction, and may shorten treatment time if they need braces or clear aligners when they’re older.
The different types of palatal expanders
The palatal expander we use for your child will depend on their age and the unique shape of their palate. There are fixed and removable options, and every expander we use is custom-made and fitted by Dr. Feil to accommodate your child’s natural palate shape and size. The most common types of palatal expanders include:
Rapid palatal expander
The rapid palatal expander, or RPE, is one of the standard expander types. It has a center screw with four branches attached to the paralleled back teeth of the upper jaw. You’ll get a small key that you’ll turn each day to activate the expander and create tension on the two palatal bones. Over time, this will widen the palate to the desired size and shape.
Removable palatal expander
The removable palatal expander is another standard option for treating children, particularly in cases that require minimal expansion. The device is similar to a clear retainer, like those we give patients once they complete orthodontic treatment, but it also has a center screw. This center screw works similarly to the RPE and requires the same gentle daily expansion for 3-6 months.
Find your child’s healthiest smile at Feil Orthodontics
Orthodontic care can benefit patients of all ages, including children. A child’s mouth changes rapidly, with a great deal of shifting and moving as they lose baby teeth and the permanent teeth erupt. If there’s any misalignment or other issue, it’s often easier to treat at a younger age while the jaw and palate are still developing.
Experienced orthodontists like Dr. Feil can identify potential problems and encourage a healthier smile using the appropriate orthodontic tools, including palatal expanders.
