Congratulations, your orthodontic treatment has started! In addition to widening the upper jaw, the palatal expander allows for the creation of more space for the eruption of the permanent teeth and correction of the bite.
This information is provided to give you information on how to activate your expander, what to expect, and hygiene instructions. If you have other questions or problems, please call the office.
Activation
We recommend activating the appliance at bedtime so that the pressure from the turn is gone by morning. If you forget one night, you can activate it once the next morning and then again that night. However, do not turn more than twice in one day.
- You will be given a key to activate the RPE.
- Place key in anterior hole of appliance, toward the front teeth.
- Push the key toward the back of the mouth until the next hole is completely visible.
- Remove the key carefully so the new hole for the next activation is completely visible.
Hygiene
Brush the appliance including the metal bars and screw in the same way you brush your teeth. When you are unable to brush after eating, swish water around in your mouth to help dislodge any food particles.
Diet
At first, eating will be more difficult; take small bites and eat soft foods until this is overcome (usually only a few days). After that, you should be able to eat almost everything you did before with some exceptions.
What To Expect
- Speech: Your speech will be affected. This is not permanent, and the best way to get used to this is to speak aloud as much as possible; try reading out loud or singing.
- Soreness: Your teeth may be sore for the first few days. To help with this you may want to take what you would normally take for a headache; however, chewing and talking are the best ways to get your mouth used to this new feeling.
- Pressure or tingling of the mouth, tongue, chees, and nose
- Space between your front teeth: Although this is a good sign from the standpoint of your treatment, it can be disheartening from a cosmetic point of view. By the time you stop turning the screw, the space may look large enough to fit another tooth. This space should close by itself within a short time.
Potential Problems
Please turn appliance as instructed. Do not continue to activate the appliance beyond this time. At your next appointment, you will be told if your expansion is completed or needs to continue.
The most common problem we see with the RPE is an incomplete activation where the key cannot be seated for the next activation. You should see the next hole completely in the RPE when the key is removed. Call us if you have this problem, and we will get you in to correct it.
If one of the arms gets bent or is pinching the gum tissue, please call so we can adjust your RPE.
If the RPE ever feels loose and you notice the bands are not cemented on the teeth, please call to have the appliance re-cemented. You should carefully follow the food list and avoid sticky, hard foods. Yes, that means no gum!
