Palate expanders

A palate expander is a device used to widen the upper jaw, creating more space in the mouth.

This helps address issues like overcrowded teeth and crossbites. By gradually expanding the upper jaw, we can improve teeth alignment and overall oral health.

How a palate expander works

A palate expander fits against the roof of your mouth and attaches to the upper molars. It consists of two halves connected by a screw. By turning this screw with a special key, gentle pressure is applied, encouraging the jawbone halves to move apart and widen the upper jaw over time.

The steps of treatment

  1. Consultation and Customization: Your orthodontist evaluates your orthodontic needs. If a palate expander is recommended, impressions of your teeth are taken to create a custom-fit device.
  2. Placement: The expander is placed in the mouth and secured to the upper molars. You’ll receive instructions on turning the screw and the schedule for doing so.
  3. Expansion Phase: Over several weeks or months, you will turn the screw as directed, gradually widening your palate. Regular check-ups help the expansion progress as planned.
  4. Retention Phase: Once the desired expansion is achieved, the device remains in place for a few months to stabilize the bones in their new position.

What a palate expander can help with

  • Improved Teeth Alignment: More space allows teeth to align properly, reducing the need for extractions and simplifying future treatments.
  • Balanced Facial Structure: Expanding the upper jaw can lead to a more balanced facial appearance.
  • Long-Term Oral Health: Proper teeth alignment can reduce the risk of tooth decay, gum disease, and jaw pain.

Who a palate expander is for

Palate expanders are often used for children and teenagers, whose jawbones are still growing and more adaptable. However, adults can also benefit from this treatment due to advancements in orthodontic technology.

MARPE stands for miniscrew-assisted rapid palatal expansion. It is designed to widen the upper jaw in older teens and adults who may no longer be ideal candidates for a traditional expander alone.

How an expander feels

Most children feel mild pressure at first, but this usually fades within a few days.
