Palatal Expander Cumming
Make Room in the Upper Jaw

Orthodontics is about so much more than braces! It can involve the use of a range of devices, each of which aims to accomplish a specific purpose. The goal is to optimize the alignment of the teeth and jaws, leading to better overall function and a decreased risk of future problems. One appliance that our Cumming team sometimes uses is known as a palatal expander. What are palatal expanders, and how do they work? Continue reading below to find out, or contact us directly to ask questions.
What Are Palatal Expanders?

A palatal expander, also called a palate expander, is an orthodontic appliance that has the goal of widening the upper dental arch. It does so by gently placing pressure on the two halves of the upper jaw, gradually moving them apart. This affects bone development and can result in a permanent expansion of the upper jaw. As a result, the patient is at a reduced risk of overcrowded teeth, bite misalignment, and other problems.
Palatal expanders are usually used during childhood, when a patient is still growing, and it is easier to influence the growth of their jaw. In some cases, though, these devices are used on teens and adults (though the entire treatment process may be more complex).
How Do Palatal Expanders Work?

Most patients should start using a palatal expander when they are 7 or 8 years old. If your child is in that age range and has not yet undergone an orthodontic evaluation, now is the time!
If our team determines that a palatal expander is necessary, we will determine which type of device would be best. A removable palatal expander looks like a retainer and can be used in cases where only slight widening of the dental arch is required.
A rapid palatal expander is bonded onto the back teeth. It has a tiny screw that should regularly be turned with a special key in order to continually influence the jaw’s growth.
Depending on circumstances, your child might need to use their palatal expander for 3 – 6 months to achieve the desired results.
Caring for a Palatal Expander

Here are some things you can do to help your child take good care of their palate expander:
- Encourage your child to maintain excellent oral hygiene by brushing thoroughly around the expander and flossing daily to prevent plaque buildup and gum irritation. (If the expander is removable, it should be taken out of the mouth regularly for cleaning.)
- Ensure your child avoids sticky, hard, and chewy foods that might damage the fixed expander, such as caramel, chewing gum, or hard candies.
- Monitor your child’s comfort level and reassure them that temporary soreness or pressure is normal. Offer soft foods during the adjustment period if necessary.
- Take your child to all scheduled follow-up appointments to monitor progress and ensure the expander is functioning as intended.
- Remind your to use the expander as instructed. This involves regularly turning the key as instructed by their orthodontist.
Palatal Expander FAQs
Can Palatal Expanders Be Used on Teens and Adults?
Palatal expanders are most commonly used for children because their bones are still developing and respond well to orthopedic guidance. However, you may still benefit from this treatment as a teenager or adult, although the process might require more time and careful planning. The flexibility of your palate decreases with age, so your orthodontist will assess your unique situation before recommending a palatal expander.
As an orthodontic practice in Cumming, we assess every patient individually to determine suitability for expanders. For teens and adults, additional methods, such as surgically assisted expansion, may sometimes be necessary. We will discuss your goals, review your dental and medical history, and conduct detailed imaging to guide our recommendations.
Are There Any Eating Restrictions with a Palatal Expander?
During treatment with a palatal expander, your child will need to make some changes to their diet in order to avoid damaging the appliance. Hard, sticky, and chewy foods can loosen or break the expander, which may delay progress. We recommend a diet of primarily soft foods that are not too chewy or sticky.
Our practice will provide you with a list of foods to avoid and offer tips for maintaining a healthy and satisfying diet for your child during treatment. We are always available to answer your questions or provide additional guidance regarding food choices.
Do Palatal Expanders Hurt?
When your child’s palatal expander is first placed, they might feel pressure against their teeth and palate. This sensation is normal and indicates the device is working to create space. Some individuals experience mild discomfort or soreness, especially following adjustments, but this feeling usually fades within a few days. You can provide over-the-counter pain relief and soft foods to alleviate any temporary discomfort.
Our practice will guide you through what to expect and offer support as your child adjusts to the expander. We will monitor their progress at regular appointments and address any concerns about pain or discomfort. If your child ever experiences severe or persistent pain, we urge you to contact us promptly so we can evaluate the appliance and make necessary adjustments.
What Should Happen After Treatment with a Palatal Expander?
After the palatal expander has completed its work, we will remove the appliance and evaluate the results. Your child may experience a marked improvement in their bite and the alignment of their upper jaw.
We place great importance on retention following expansion. Your child will likely need a retainer to maintain the new width of their palate and prevent relapse.
The next phase often involves wearing braces or clear aligners to refine the positioning of the teeth. We will schedule follow-up visits to monitor your child’s progress and address any ongoing needs.
What Should I Do if My Child’s Expander Breaks?
If your child’s palatal expander breaks, you should contact our office immediately for guidance. Avoid trying to adjust or repair the appliance yourself, as this could cause further damage or discomfort. In the meantime, your child should avoid eating hard or sticky foods and be careful not to touch the expander with their fingers or other objects.
We treat broken appliances as a priority and will arrange to see your child as soon as possible. During the visit, we will assess the extent of the damage and decide whether to repair or replace the expander. Our team will work to minimize disruption to your child’s treatment; we want their progress to get back on track ASAP!
What Are Some Signs My Child Might Need a Palatal Expander?
Bringing your child to us is the best way to determine if they need a palatal expander. Here are some indications that they should come in for an evaluation:
- Your child’s teeth are crowded or overlapping in their upper jaw.
- Your child experiences difficulty breathing through their nose, especially at night. They may be prone to frequent mouth breathing.
- You notice that your child has a crossbite, where some of the upper teeth sit inside the lower teeth when they bite.
- Your child’s general dentist expresses concerns and recommends that you bring them to an orthodontist.
Can My Child Eat Normally with a Palatal Expander?
While your child may need to make some temporary adjustments to their eating habits, most foods can be enjoyed with a palatal expander in place. We recommend that you encourage your child to chew slowly and carefully, especially in the days following placement or adjustment. Soft foods are preferable during times of discomfort, but after the initial period, your child can gradually return to a more typical diet, avoiding only foods that could damage the appliance.
Our practice will provide you with a list of foods to avoid and offer specific guidance tailored to your child’s needs. Eating instructions for fixed and removable palatal expanders may differ. (Since removable expanders should be taken out at mealtimes, they allow for more dietary freedom.)
Will My Child’s Speech Be Affected?
It is common for children to notice slight changes in their speech when a palatal expander is first placed by our Cumming team. For example, you may hear your child speaking with a lisp or experiencing difficulty pronouncing certain sounds. This adjustment period is usually short-lived, and most children adapt within a week or two. If speech changes seem severe or do not improve after a reasonable period of time, contact our team so we can provide advice.
What Are the Signs of an Allergic Reaction to the Expander?
Although allergic reactions to palatal expanders are rare, it is important for you to monitor your child for any unusual symptoms. Signs could include swelling of the mouth or lips, persistent redness, itching, or rash near the appliance. If you suspect your child is experiencing an allergic reaction, contact our office immediately. We will assess the situation, determine the cause, and take appropriate action to ensure your child’s safety and comfort. They might need a new expander that is made of different materials.
How Will I Know the Expander Is Working?
You may notice small gaps appearing between your child’s front teeth as a visible sign that the expander is creating space. Other indications include improvements in bite alignment and the way your child’s upper jaw fits together with the lower jaw. We will monitor progress at regular appointments and take measurements to ensure the appliance is functioning as intended. We encourage you to reach out with any questions about changes you observe, and we will provide ongoing updates and reassurance throughout the treatment process.
