Palatal Expanders: What They Do
Expanders are an orthodontic tool that orthodontists use to help patients who may need to have their jaw structure changed. Palatal expanders have several benefits, particularly for those who have crowded teeth or issues with their teeth not being correctly aligned. Typically, expanders are used for children and teens whose bones may still be growing.
What do palatal expanders do?
The purpose of the expander is to correct teeth misalignment. Expanders are often necessary when there is a lack of space for teeth to fill in or if there is a crossbite between arches. A crossbite refers to a specific alignment where the upper teeth fit into the lower teeth or vice versa. The dental arch refers to the top or bottom sections of the teeth. The expander works to realign the arches and bring them into their proper alignment.
Why would you need an expander?
Children often need expanders because their jawbones are still forming and developing. They are ideal for preventing many types of misalignment, which can lead to inflammation, decay, and weakness in the teeth. The expander itself is a silver device placed on the arch that runs along the teeth to adjust them. Many times, both arches will be connected with a screw in the mouth, which the patient or their parent will need to turn to adjust. The product is made specifically for each patient's unique jaw structure. You will likely feel a difference in pressure on your teeth at the time of adjustment. Some discomfort is normal for the first few days into treatment, but it is typically not a painful treatment process.
What is it like to wear them?
There are many different types of palatal expanders. Some of them include:
- Removable palate expander. Looks familiar to a retainer. It consists of chrome and is removable for brushing or eating. This type of expander is common for those who only need to widen their jaw slightly.
- Rapid palate expander. Fits in the roof of the patient's mouth and attaches to the back of their upper teeth for stability. There is a tiny screw in the middle that the patient will turn every day. Over time, this tension will move the bones apart and widen the jaw.
- Surgically assisted rapid palate expander (SARPE). Used for moderate to severe cases or adults with fully developed facial bones. It is placed along the mid-palatal suture (the point where the left and right sides of the palate meet). Like rapid palate expanders, SARPE expanders rely on the back upper teeth for support.
- Hyrax expanders. Consists of bands that wrap around the back molars and are affixed with dental adhesive. They are similar to removable expanders but are held in place with screws to hold them in place.
