Temporomandibular joint disorder (TMD) affects the jaw joints and surrounding muscles, causing pain, clicking, popping, difficulty opening the mouth, and chronic headaches. At Harmony Dental Care in West Covina, Dr. Khaef provides comprehensive TMJ diagnosis and treatment using custom oral appliances, bite therapy, and a multi-disciplinary approach to deliver lasting relief. TMJ disorders can result from bruxism, injury, arthritis, bite misalignment, or stress. Our thorough evaluation identifies the root cause of your symptoms so we can target treatment effectively rather than simply masking the pain. Patients from Valinda, Irwindale, and South San Jose Hills find lasting TMJ relief at our West Covina office.

TMJ disorder presents with a range of symptoms including jaw pain or tenderness, clicking or popping sounds when opening or closing the mouth, difficulty or pain while chewing, jaw locking in the open or closed position, facial pain, ear pain or fullness, headaches (especially near the temples), and neck and shoulder tension.
Custom TMJ splints. Precisely fabricated oral appliances that reposition the jaw, reduce muscle strain, and protect teeth from grinding.
Bite equilibration. Careful adjustment of tooth contacts to eliminate bite interferences that contribute to TMJ strain.
Physical therapy coordination. Referrals to orofacial pain specialists and physical therapists for muscle rehabilitation and stretching protocols.
Lifestyle modifications. Guidance on stress management, jaw relaxation techniques, diet modifications, and habit changes that reduce symptoms.
Thorough diagnostic approach. We evaluate your jaw joints, muscles, bite, wear patterns, and medical history to identify all contributing factors.
Conservative-first philosophy. We start with the least invasive treatments (splints, physical therapy, lifestyle changes) before considering more advanced interventions.
Integrated care. TMJ treatment at Harmony Dental connects to our bruxism, headache, and sleep apnea services for comprehensive relief.
Convenient location. Our comprehensive TMJ evaluation and treatment serve patients from Valinda, Irwindale, South San Jose Hills, and neighboring communities.
Harmony Dental brings 20 years of clinical experience diagnosing and treating complex temporomandibular joint (TMJ) disorders for the eastern San Gabriel Valley also known as the greater Los Angeles area community. Our dedication to finding the non-surgical root cause of your jaw pain is backed by our 200+ 5-star reviews.
Your comprehensive TMJ evaluation will be expertly managed by Dr. Nguyen. As a highly trained DMD, they specialize in the complex neuromuscular relationship between your teeth, jaw joints, and facial muscles. Our practice is also incredibly proud to be recognized with 5 star dentist of West Covina.
Common symptoms include a clicking or popping sound when you open your mouth, pain while chewing, lockjaw, chronic tension headaches, ringing in the ears, and unexplained neck or shoulder pain. If you are experiencing these, we utilize 3D Digital X-rays, 3d scanners, digital impressions, and pain-free laser dentistry to accurately pinpoint the source of the joint dysfunction.
Absolutely. The vast majority of TMJ cases can be treated entirely without surgery. We prioritize conservative, non-invasive therapies such as custom-fitted oral orthotics (splints), bite equilibration, and muscle relaxation techniques. We also offer local anesthetic, powerful numbing gel, warm blankets and noise-canceling headphones so your evaluation and fitting visits are completely stress-free.
The cost of TMD therapy varies widely depending on whether your condition requires a simple bite guard to stop nighttime grinding or a more advanced neuromuscular orthotic to continuously realign your jaw. Because living pain-free is vital, Harmony Dental proudly offers CareCredit, Sunbit, Alpheon, Credit Card and in-house membership plan to make your custom treatment plan highly affordable.
