A palatal expander may be recommended by your Coquitlam orthodontist to help move teeth so they fit together better.
A palatal expander "expands" (or widens) the upper jaw by putting gentle pressure on the upper molars each time an adjustment is made. This is done so that the upper and lower teeth fit together better.
When you achieve the desired expansion, you will wear the appliance for several months to solidify the expansion and to prevent regression.
In a well-lit area, tip the patient's head back.
Place the key in the hole until it is firmly in place.
Push the key toward the back of the mouth. The fender will rotate and the new hole will appear. The rotation stops when the key meets the back of the expander.
Press back and down toward the tongue in order to remove the key from the hole. The next hole in which to insert the key should now be visible.
