One in eight Americans suffer from recurring severe headaches, with 80% caused by muscle tension. Tension headaches are often related to dental issues, as muscles holding the jaw and head become strained from an improperly aligned bite over time. Symptoms of dental-related headaches include pain behind the eyes, jaw muscles, neck, and shoulders. An unstable bite forces muscles to overwork to keep the head balanced, leading to pain. Dental treatments like neuromuscular dentistry can help realign bites and relax strained muscles to reduce tension headaches.
