TMJ and Sleep Disorders

Many patients who come in for jaw pain turn out to have a sleep problem too, and many who come in exhausted turn out to have a jaw problem. Dr. Herber completed a mini-residency at the Las Vegas Institute covering TMJ disorders, sleep disorders, and craniofacial pain, and he evaluates all three together rather than in isolation.

How are TMJ disorders and sleep problems connected?

The jaw, the airway, and the muscles of the head and neck all share the same small space. When the lower jaw sits back or the bite is unstable, the tongue and soft tissue have less room, and the airway narrows during sleep. The body responds by clenching and repositioning the jaw to reopen the airway, which loads the joint night after night. That is why jaw pain and poor sleep so often show up in the same patient.

What are the signs that sleep may be part of my TMJ problem?

Common signs include waking with a headache, waking with a sore or tight jaw, grinding or clenching at night, snoring, waking unrefreshed after a full night in bed, daytime fatigue, and a partner noticing pauses in your breathing. Worn or chipped teeth and scalloped edges on the tongue are physical signs Dr. Herber looks for during an exam.

Can a dentist diagnose sleep apnea?

No. Obstructive sleep apnea is a medical diagnosis, and it requires a sleep study interpreted by a physician. What a dentist can do is screen for it, recognize the oral and dental signs, and refer you for proper testing. Dr. Herber works alongside your physician rather than in place of one.

How does oral appliance therapy work for sleep?

A custom oral appliance holds the lower jaw in a slightly forward position during sleep, which opens the airway behind the tongue. It is worn only at night and fitted specifically to your bite. Physicians commonly consider oral appliance therapy for patients with mild to moderate obstructive sleep apnea, and for patients who cannot tolerate CPAP. Your physician determines whether it is appropriate for you.

Is a sleep appliance the same as a TMJ orthotic?

No, though they can look similar. A TMJ orthotic is designed to decompress and stabilize the joint. A sleep appliance is designed to advance the lower jaw and open the airway. The two goals sometimes work together and sometimes pull against each other, which is why the jaw joint needs to be evaluated before a sleep appliance is made. Advancing the jaw in someone with an inflamed joint can make the joint worse.

Can teeth grinding be caused by a breathing problem?

Often, yes. Nighttime grinding and clenching are frequently the body's response to a narrowed airway rather than a habit or a stress problem on their own. This matters because a standard night guard protects the teeth but does nothing about the cause. If breathing is driving the grinding, treating only the teeth leaves the underlying problem in place.

Why does my jaw hurt more in the morning?

Morning jaw pain and morning headaches usually point to something happening during sleep rather than during the day. Clenching, grinding, and airway-related jaw repositioning all happen while you are unconscious and can load the joint for hours. If your symptoms are worst when you wake up and ease as the day goes on, that pattern is worth mentioning at your evaluation.

What happens at an evaluation?

Dr. Herber examines your jaw joints, bite, and airway-related signs together, and reviews your symptom history including sleep. If the findings suggest a breathing disorder, he refers you to a physician for testing before any appliance is made. If the joint is the primary problem, treatment starts there.
