You may be suffering from the disorder called sleep apnea, which is the cease or cutoff of breathing while you sleep. Obstructive sleep apnea can be effectively treated by our dentistry with a treatment called Oral Appliance Therapy (OAT). We will provide a custom oral device, similar to a retainer or sports mouth guard. A tongue-retaining device may be provided if your sleep apnea is due to your tongue obstructing your airway. A headgear may be provided to properly reposition your jaw if your sleep apnea is due to the improper alignment of your jaw. The devices are all removable and only worn during sleep.
