Palatal Expander From Your Orthodontists


An ideal way to widen a narrow palate and slowly expand the upper jaw, these appliances are instrumental in creating space for teeth that are experiencing significant crowding. The upper palate expander works by applying gradual pressure on the upper jaw bones, encouraging them to move apart and thereby increasing the width of the palate. This not only helps in alleviating crowding but also improves the overall alignment and function of the teeth and jaw over time.

When should someone have one placed?

Though many children will have an orthodontics expander recommended by their orthodontist while their mouth is still developing, some young adults can also benefit from one though their treatment time is often lengthier.

How does it work?

Attached to the roof of a patient’s mouth and anchored in place to their back molars, the device is initially activated by our doctor with a key that, once turned, gently pushes the expander in an outward motion. Over time and with daily turns that are performed by the patient or their parent, the palate arch is widened, creating more room for crowded teeth and a healthier bite. When the palate has reached its ideal width, the expander will be left in place for a few months to solidify the expansion and prevent any regression from taking place.

Is wearing one painful?

Because the bones in the upper jaw are being moved, there will likely be some pressure in the upper facial region. In situations where discomfort is significant, a pain reliever will help. Additionally, regular adjustments to the upper jaw expander may be necessary to ensure the treatment progresses smoothly. These adjustments can contribute to the sensation of pressure but are essential for achieving the desired outcome.

A mouth expander for braces is a specialized orthodontic device used to widen the upper jaw, creating space for overcrowded teeth and improving bite alignment, essential for preparing the mouth for braces or enhancing their effectiveness.

Are there any foods that shouldn’t be eaten while wearing this appliance?

Sticky or chewy foods, including caramels, gum, or taffy, should be avoided, as should hard foods like nuts, ice, and popcorn. Foods like apples, celery, and carrots should be cut into small pieces to avoid damage to the tooth expander and other orthodontic appliances.
