How can i cope with an orthodontic appliance?

More Specific: I must assume your mean a removable orthodontic appliance. The more you wear it, the more your mouth gets used to it in your mouth. It is normal for the mouth to produce saliva when something new like a retainer is placed in the mouth. If discomfort is involved, go back to your orthodontist to have it adjusted. Without knowing what type of orthodontic appliance your have, the answer is difficult.

What type: Fixed and removable appliances create different management problems. Please be more specific as to what type of appliance, and what are your symptoms.
