My Jaws and Teeth Hurt. What can I do?

Jaw Pain and Tooth Discomfort from Clenching and Stress: Causes and Solutions

Jaw pain and tooth discomfort are often linked to chronic stress and a condition called bruxism—unconscious clenching or grinding of the teeth, especially during sleep. This habit can cause worn enamel, fractured teeth, jaw joint pain, facial soreness, and headaches. If left untreated, these issues may disrupt chewing, speech, and sleep quality.

Stress triggers the body’s “fight or flight” response, leading to increased muscle tension, including in the jaw. In bruxism sufferers, this tension often translates into excessive biting forces that can damage teeth and strain the temporomandibular joints (TMJs). Many people are unaware they clench or grind, especially at night, which is why early identification and intervention are key.

One of the most effective conservative treatments is occlusal splint therapy. A custom-fitted night guard worn during sleep creates a protective barrier between the upper and lower teeth. It distributes pressure more evenly, reduces muscle fatigue, and protects against further enamel wear. Patients commonly report less jaw tension, fewer headaches, and improved comfort upon waking.

In some cases, clenching may be linked to obstructive sleep apnea (OSA)—a condition where the airway repeatedly collapses during sleep. Bruxism may serve as a subconscious effort to keep the airway open. Treating the underlying sleep apnea with oral appliance therapy can reduce both nighttime grinding and daytime jaw pain.

For lasting relief, patients should receive a comprehensive evaluation that includes dental assessment and sleep screening. Dentists trained in dental sleep medicine can work with physicians to provide integrative care.

Addressing jaw pain from clenching involves more than symptom relief—it requires treating the root causes. Through stress management, dental intervention, and sleep therapy, patients can restore oral comfort and improve overall well-being.
