About Palatal Expanders

At Lancaster Pediatric Dental Associates, we offer palatal expanders to help improve young patients’ jaw, bite, and oral function. Placed on the top of the mouth, palatal expander connects to molar teeth on each side of the upper arch. Its purpose is to slowly stretch the upper arch and cartilage, so your child’s jaw has the best position and size for their adult teeth. For younger patients with a narrow, upper arch, the top teeth may not come in, or if they do, it could cause misalignment and overlap. A palatal expander carefully expands the upper arch, which provides the necessary space for adult teeth to grow in properly. Please schedule an appointment with our pediatric dentists in Lancaster, PA to receive a consultation for your child. We can assess their teeth and provide the next best steps.

Is My Child A Good Candidate for Palatal Expanders?

If your child has a narrow upper palatal, they may benefit from a palatal expander. One of our skilled orthodontists can enhance your child’s oral function with a palatal expander, which in the long run, will help with eating and speaking. A palatal expander can help with several orthodontic problems, such as bite problems and crowded teeth. After your child finishes this part of their orthodontic therapy, this particular appliance may also decrease the risk of cavities and gum disease by encouraging your child’s teeth to grow into their proper place. The best time to use a palatal expander is before the growth plates in the top of your child’s mouth fuse, which occurs in the mid-teenage years.

What to Expect with Palatal Expanders

Palatal expanders fasten to the upper arch with bands that we place and bond around the molar teeth. Typically, the appliances have a wire, coil, and a device that goes across the hard palate, from one part of the mouth to the other. Sometimes, your child needs to use a key that goes into the center part of their appliance, which stretches the expander. As you continue to do this process, your child’s upper arch begins to widen. We will let you know how often to turn the key. At first, the appliance will cause mild pressure in the upper jaw, and your child may have difficultly chewing and speaking until getting used to it.

Additionally, plaque and food tend to gather near the palatal expander’s parts. Because of this, your child may have difficulties cleaning and flossing. We recommend helping your child with these parts of their daily routine to ensure their teeth stay healthy. Depending on their needs, our orthodontists may also suggest additional cleaning tools to help during this particular part of their orthodontic care.


When wearing the palatal expander, it’s pretty common for your child to have spaces occur between their teeth, so please don’t be concerned. Our orthodontists will provide information on when to schedule the next follow-up visits, so they can continue to assess your child’s oral health and development during this process. At a follow-up appointment, a team member may turn the key to adjust the expander and review the teeth to determine if your child has any areas that they need to focus on at home. This will prevent cavities and other oral issues. We also provide a timeline on how long your child should wear the appliance. Generally, they need to wear it for around 6 – 9 months. In addition to the orthodontic care, your child should still undergo cleanings and dental exams.

Insurance Coverage

Palatal expanders may be covered in part by dental insurance. Our team can get in touch with your insurer to understand your coverage and calculate your out-of-pocket costs. If you aren't using insurance, we can discuss the payments we accept, such as medical financing.
