Palatal Expander
For some patients, a narrow upper jaw can cause issues like crowding and bite problems. A palatal expander is a special appliance designed to gently and gradually widen the upper jaw. This creates the necessary space for teeth to align properly, resulting in a broader, more beautiful, and healthier smile.
How Does the Expander Work?
The palatal expander is a custom-fit appliance that sits on the roof of the mouth. It works by applying gentle, steady pressure on the upper molars. Over a period of several weeks, this pressure encourages the two halves of the palate to separate and grow wider. This process is most effective in younger patients whose bones are still developing.
Once the desired expansion is achieved, the appliance will remain in place for several more months. This gives the new bone time to solidify, ensuring the results are stable and long-lasting.
How to Adjust Your Palatal Expander
Dr. Ellis will give you a special key and a schedule for adjusting the expander at home. It’s a simple process that only takes a moment.
1
Step 1: Get Ready
In a well-lit area, have the patient tilt their head back so you can see the appliance clearly.
2
Step 2: Insert the Key
Insert the key firmly into the small hole in the center of the expander’s screw mechanism.
3
Step 3: Push to the Back
Gently but firmly, push the key towards the back of the mouth (towards the throat). You will see the screw turn, and a new hole will appear. Stop pushing when the key can’t go any further.
4
Step 4: Remove the Key
Carefully remove the key by pushing down (towards the tongue) and back. Be sure not to accidentally reverse the turn you just made. The new hole should now be visible and ready for the next adjustment.
What to Expect
- Case is King: When your retainer is not in your mouth, it should ALWAYS be in its protective case. Never wrap it in a napkin—this is the most common way retainers get lost!
- Keep it Cool: Keep your retainer away from heat. Avoid leaving it in a hot car, near a stove, or in hot water, as it can warp.
- Pets are Curious: Pets, especially dogs, love to chew on retainers. Keep your case closed and out of their reach.
