What is a Dental Sleep Medicine and TMJ clinic?

We focus on helping patients manage their snoring, sleep apnea , Jaw joint clicking, popping, locking and pain and leave the cleanings, checkups and dental work to the dental office they have already. It is not necessary for you to leave your current dentist and once an appliance is delivered we communicate with your dental office so they are aware of the appliance type and how to handle it during any dental work that is needed.
