Teeth grinding, also known as bruxism, is commonly associated with worn teeth and jaw discomfort, but it can also contribute to recurring headaches. Many patients are unaware that their headaches may be connected to what is happening during sleep or times of stress.

Increased Strain on Muscles 

Grinding places excessive strain on the muscles of the jaw, face, and temples. These muscles are closely connected to the areas where tension headaches typically develop. When they are overworked or fatigued, pain can radiate upward toward the head, often presenting as a dull, persistent ache.

Night Time Grinding

Nighttime grinding is especially problematic because it often goes unnoticed. Patients may wake with headaches in the morning, stiffness in the jaw, or soreness around the temples without realizing the cause. Over time, this repeated muscle tension can lead to chronic discomfort.

Increased Stress Exposure

Stress is a common contributing factor. During periods of anxiety or concentration, patients may clench unconsciously, even during the day. This sustained pressure increases muscle fatigue and can trigger headaches that feel similar to sinus or migraine pain.

Chewing Surfaces and Cracked Enamel 

Dental signs can provide important clues. Flattened chewing surfaces, cracked enamel, or increased tooth sensitivity often accompany bruxism. Jaw clicking or difficulty opening fully may also be present, indicating strain on the temporomandibular joint.

Treatment typically focuses on reducing muscle strain and protecting the teeth. Custom nightguards are commonly recommended to prevent direct tooth contact and distribute pressure more evenly. Addressing stress through relaxation techniques or lifestyle adjustments can also reduce grinding frequency.

If headaches are persistent and unexplained, evaluating dental factors such as grinding can be an important part of the conversation. Identifying and managing bruxism not only helps protect the teeth but can also significantly improve overall comfort and quality of life.
