Patients introduced to airway dilator treatment may at first experience a temporary increase in salivation and perhaps some tenderness in the jaw joint area during the adjustment period. For patients who wear the appliances for the long term, there may be changes to the bite relationship as well as individual tooth alignment. If these events should occur, they are usually reversible if intercepted in the first few months. Your treatment will continue after the initial period for annual check-ups so that any possible side effects can be addressed.
