Snoring is often dismissed as a nuisance, but persistent or loud snoring can indicate that the airway is becoming restricted during sleep. While factors such as nasal congestion, sleeping position and alcohol can contribute to it, the structure and position of the jaw may also play a role.

According to Dr. Amparo David, D.M.D., owner of TMJ & Sleep Therapy Centre of New England, the lower jaw is an important part of the airway equation. When the jaw sits farther back, it can reduce the space available for the tongue and contribute to narrowing of the airway  during sleep. Dental and oral features such as a narrow palate, dental crowding or changes in the bite may also provide clues that warrant further evaluation.

Snoring accompanied by pauses in breathing, choking or gasping, morning headaches, difficulty concentrating, daytime fatigue or dry mouth may be signs of obstructive sleep apnea. Because snoring can have multiple causes, an evaluation can help determine whether the issue is related to the airway, jaw position, nasal breathing or another factor.

For some adults, professionally fitted oral appliances can help reduce snoring and treat certain cases of obstructive sleep apnea by gently positioning the lower jaw forward during sleep. Unlike over-the-counter devices, custom appliances can be evaluated and adjusted according to an individual’s jaw, bite and airway needs.

“Snoring can be one of the first signs that something is happening with the airway during sleep,” explains David. “Looking at the jaw and oral structures can provide another important piece of the puzzle.”

Persistent snoring does not necessarily mean that someone has sleep apnea, but it is worth discussing with a qualified healthcare professional, particularly when other symptoms are present. A comprehensive evaluation can help identify potential contributors and determine whether further sleep testing or treatment is appropriate
