Bruxism is the involuntary grinding, clenching, or gnashing of teeth that affects approximately 10% of adults and up to 15% of children. Left untreated, chronic bruxism can lead to worn enamel, cracked teeth, jaw pain, headaches, and even temporomandibular joint (TMJ) disorders. At Harmony Dental Care in West Covina, Dr. Khaef provides comprehensive bruxism diagnosis and treatment to protect your teeth and relieve discomfort.
From custom-fitted night guards to bite equilibration therapy, our personalized approach addresses the root cause of your grinding—not just the symptoms. With hundreds of five-star reviews, advanced technology, and a genuine commitment to your comfort, we help you safeguard your smile for the long term.
Patients from Valinda, Charter Oak, and Walnut come to Harmony Dental Care for expert bruxism diagnosis and custom night guards.

Many people grind their teeth during sleep and are unaware of the habit until damage becomes visible. Common signs include: flattened, chipped, or fractured teeth; tooth sensitivity or pain; jaw muscle soreness or stiffness (especially in the morning); dull headaches originating near the temples; earache-like pain without an ear infection; and indentations along the edges of the tongue. If you or your partner notice grinding sounds during sleep, or if you experience any of these symptoms, scheduling a dental evaluation is an important first step.
Bruxism has multiple contributing factors including stress and anxiety, which are the most common triggers for both awake and sleep bruxism. Misaligned bite or crooked teeth can create uneven contact forces that promote grinding. Sleep disorders such as obstructive sleep apnea are closely associated with nocturnal bruxism. Lifestyle factors including caffeine, alcohol, and certain medications (particularly SSRIs) may also increase grinding frequency.
The most effective first-line treatment for sleep bruxism is a custom-fabricated night guard (occlusal splint). Unlike generic store-bought guards, our custom appliances are precisely molded to your teeth using digital impressions, providing a comfortable fit that properly distributes bite forces and prevents tooth-on-tooth contact while you sleep.
If your bruxism is related to an uneven bite, Dr. Khaef may recommend occlusal adjustment—carefully reshaping specific contact points on your teeth to create a more balanced, harmonious bite that reduces the stimulus to grind.
For teeth that have already sustained significant wear, cracks, or fractures, we offer dental crowns, bonding, and veneers to restore strength, shape, and aesthetics. Addressing the damage while also treating the underlying bruxism ensures long-term protection.
When bruxism has contributed to TMJ dysfunction, we integrate our TMJ treatment protocols—including splint therapy, physical therapy referrals, and lifestyle modifications—into your overall care plan.
