What Is An Orthodontic Palatal Expander?
Are your teeth misaligned? Or is your bite causing problems? Contact Yorkshire Dental Suite. We offer a wide range of orthodontic treatments, each made with one goal in mind – to give you the beautiful, healthy smile you deserve.
Its name may sound intimidating, but a palatal expander is a well-established device in the field of orthodontics. Most commonly used for children and teenagers, the appliance is designed to guide jaw growth, while supporting the results of fixed braces and aligners.
What is an orthodontic palatal expander?
This small, custom-made appliance widens the upper jaw while it is still developing. Expanders are very effective in the correction of certain bite problems caused by a narrow upper jaw, including crossbite.
So how does a palatal expander work? Put simply, the device applies controlled pressure to the palate. This can increase the space available for the teeth and help create a more balanced bite.
Why would someone need a palatal expander?
Not all patients need to use this device, with only a very small number benefiting from its use, but they are necessary when the patient’s upper jaw is causing problems such as the following:
- Crossbite: The misalignment of the upper and lower teeth when you close your mouth
- Crowding: The teeth twist and overlap due to a lack of space within the jaw
- Underbite: The lower teeth overlap your upper teeth
- Impacted teeth: There isn’t enough space for a tooth to grow through
What age is best for a palatal expander? The ideal window is between 7 and 12 years (as the jawbone is still developing) but since everyone grows at a different rate, this is not a set requirement. Adults are also able to have this device fitted but it is a much more complex process as their jawbone has already finished growing.
What are the different types of palatal expanders?
The right type of palatal expander for you will depend on factors such as your age and jaw development. The most commonly used expanders are listed below – let’s go into more detail about how each one works.
Type | How does it work? |
Rapid palatal expander (RPE) | A fixed appliance that uses a central screw to gradually widen the jaw. It cannot be removed without the assistance of a dentist |
Removable palatal expander | Closely resembling a retainer, this appliance is ideal for mild cases and gradual expansion. It is much easier to keep clean and eat due to its removability |
Mini-screw assisted rapid palatal expander (MARPE) | Uses tiny temporary anchorage screws in the palate to help direct expansion forces towards the upper jaw. Considered for older teenagers and adults |
Surgically assisted rapid palatal expander (SARPE) | Combines surgery with a palatal expander. Carefully planned cuts are made in the upper jaw before the expander is used to gradually widen it |
How much do palatal expanders cost?
If you are under the age of 18 and there is a strict clinical need for a palatal expander, you may be able to claim the appliance for free on the NHS. Otherwise, you will need to seek treatment at a private dentist and cover the cost yourself.
The price varies greatly depending on which palatal expander you choose, so it is hard to give a definitive answer. The most common type (RPE) tends to be on the lower end of the scale of £500 upwards in the UK, whereas MARPE expanders typically cost over £6,000. Contact your dentist for more information.
The benefits of palatal expanders – and the risks

Does a palatal expander hurt?
Mild pressure is very common, especially in the first few days following the expander being fitted or adjusted. This can be managed with your typical over-the-counter pain medication. If your discomfort is severe, contact your dentist.
How long do you wear a palatal expander?
There is no definitive answer, but the timeframe of your treatment is largely influenced by the severity of your malocclusion. Some patients only wear a palatal expander for a few weeks, whereas others may need to wear one for up to 12 months.
Can you eat normally with a palatal expander?
There are certain foods you shouldn’t eat while wearing a palatal expander. It’s very similar to wearing fixed braces – try to avoid hard, sticky foods that could cause damage to the appliance.
