- A palate expander is a non-invasive and non-surgical oral appliance. It widens a narrow maxillary arch and creates more space for the eruption or movement of teeth.
- Palate expanders are a more common treatment for pre-adolescent children, but adults can use them as well.
- Palate expanders are generally not painful. However, initial use may cause increased saliva production.

How can a palate expander help your treatment? Here's everything you need to know.
How do palate expanders work?
A palate expander works by placing pressure on both sides of the upper jaw to create a wider palate. This allows more room for the teeth to erupt and/or creates space for movement in the case of orthodontic treatment. They are common for individuals who have narrow palates.
Palate expanders are non-invasive and non-surgical.
Palatal expanders types
There are three types of palatal expanders: Hyrax rapid, Quad helix, and Haas.
The Hyrax appliance, also called a rapid palatal expander, is attached to the maxillary molars by cementing metal bands to the molars. There is a small screw in the middle that is turned periodically to slowly widen the palate.
A quad helix expander is also attached to the maxillary molars by bands that are cemented around the molars. The appliance has 2-4 active helix springs that widen the palate. This appliance can be used to expand the palate and to correct a posterior crossbite.
Like the others, the HAAS expander works to widen the palate by putting pressure on the maxillary molars. It is made of an acrylic base that is shaped to fit the roof of your mouth. A bone screw is placed in the middle of the acrylic and is then loosened or tightened to apply pressure. The expander is held in place by wires that are fixed to the teeth.
How to adjust the palate expander?
Your dentist or orthodontist will instruct you on how to use the key that comes with your palate expander. While most individuals will adjust their expander daily, be sure to follow the specific instructions given by your provider. Do not adjust the appliance more than once a day.
To adjust your appliance, insert the key into the hold that is in the middle front part of your expander. Push the key towards the back of your mouth - gently! You’ll feel some resistance and you will notice that the next hole rotates into position for the next adjustment. Remove the key by pushing it towards your throat and out of the keyhole.
Palate expander side effects
When your expander is first placed, you may notice an increase in saliva production. This should go away quickly as you get used to the expander. Other than that, you should have absolutely no side effects.

Are there alternatives to palate expander?
Braces are often used after a palate expander has had time to widen the palate. While braces can also treat a narrow arch, a palate expander may shorten the length of time it takes to correct the alignment of the teeth.
In some cases, orthognathic surgery may be required.
