Published studies show that short-term side effects of oral appliance use, in general, may include excessive salivation, difficulty swallowing (with the appliance in place), sore jaws, sore teeth, jaw joint pain, dry mouth, gum pain, loosening of teeth, and short-term changes in the bite. There are also reports of dislodgement of ill-fitting dental restorations. Most of these side effects are minor and resolve quickly on their own or with minor adjustments of the appliance. Long-term complications include changes in the bite that may be permanent, resulting from tooth movement or jaw joint repositioning (which is the desired effect with appliance therapy). These complications may or may not be fully reversible once to remodel the jawbone, move the teeth and jaw position, the enhance craniofacial development. If not fully achieved, restorative dental treatment, orthodontic intervention, or other treatments may be required, for which you will be responsible.
