Fixed Expander

The palatal expander is a special device used to widen the upper arch or roof of the mouth. There are several reasons to widen the arch:

  • A wider arch permits the upper teeth to line up with the lower teeth, giving you a better bite.
  • A wider arch makes room to straighten crowded teeth.

The upper arch is usually expanded enough in 14-21 days. However, the appliance is allowed to remain in the mouth for 4-6 months.
During this time new bone is generating in the expanded mouth. You will notice that widening the palate also temporarily causes a space between the teeth.
Do not be alarmed! Most of the space will close again naturally.
This procedure is not painful, although there may be some initial discomfort and some feeling of pressure as the arch expands. The pressure may cause a tingling under the appliance or at the bridge of the nose. Usually, any over the counter pain reliever will effectively relieve any discomfort. If it does not, call the office so we can check the appliance.

Instructions:

Once the palatal expander has been cemented into place, please activate according to the doctor’s instructions.

Carefully insert the key into the hole in the middle of the appliance.
Gently and steadily push the key from the front toward the back of the mouth until you feel the key stop. Do not back up. Remove the key toward the throat. You automatically bring a new keyhole position forward by pushing the key as far back a possible. It will be ready for the next activation.

As a parent
Please activate your child’s appliance. Closely follow the schedule and instructions given. Be regular! It is important not to rush or delay the activation of the appliance.
