It can cause headaches, facial pain, and tooth sensitivity, mimicking symptoms of migraines or temporomandibular joint (TMJ) dysfunction.

• Maintain good dental health and address any issues with teeth alignment or grinding.
• Avoid excessive chewing or jaw clenching, especially during stressful periods.
• Use proper posture and ergonomics to reduce strain on the head and neck muscles.
