What are removable appliances? These are created to move or hold your teeth. Having this adjusted to move the teeth can sometimes make your teeth sore.

There is a tendency that the appliance will be loose or worse, it might break inside your mouth. You don’t want that to happen, right? Another thing, please see to it that you clean your removable appliance daily with a toothpaste and toothbrush. You wouldn’t want a stinky mouth.
