Many chronic headaches and migraines originate from problems in the jaw, bite, or facial muscles rather than purely neurological causes. Temporomandibular joint (TMJ) dysfunction, teeth grinding (bruxism), and bite misalignment can trigger recurring tension headaches, migraines, and facial pain. At Harmony Dental Care in West Covina, Dr. Khaef identifies dental-related headache triggers and provides targeted treatments to deliver lasting relief. If you suffer from frequent headaches accompanied by jaw pain, ear pain, neck tension, or facial soreness, a dental evaluation could reveal the underlying cause. Our comprehensive approach addresses the root of the problem—not just the symptoms. Patients from Valinda, South San Jose Hills, and Irwindale find lasting headache relief through our TMJ-focused dental treatments.

The temporomandibular joints connect your lower jaw to your skull and are surrounded by a complex network of muscles. When these joints or muscles are strained—from clenching, grinding, bite misalignment, or injury—the resulting tension can radiate pain to the temples, forehead, behind the eyes, and down the neck. Studies suggest that up to 70% of headaches may have a muscular component related to jaw function.
Custom oral appliances. Night guards and TMJ splints repositioned to reduce jaw muscle strain and prevent nighttime clenching.
Bite equilibration. Adjusting the contact points of your teeth to create a more balanced bite, reducing muscle overwork.
Trigger point therapy referrals. Coordination with physical therapists who specialize in orofacial pain for comprehensive muscle rehabilitation.
Restorative correction. Crowns, orthodontics, or other restorations to correct structural bite issues contributing to headaches.
Comprehensive TMJ evaluation. We assess your jaw joints, muscles, bite alignment, and tooth wear patterns to identify all contributing factors.
Personalized treatment plan. No two patients are alike. We tailor treatment to your specific triggers and symptoms.
Multi-disciplinary approach. We coordinate with physicians and physical therapists for comprehensive headache management.
Convenient location. If you suffer from chronic headaches in Valinda, South San Jose Hills, or Irwindale, a dental evaluation at our West Covina office could reveal the underlying cause.
