TMJ and Bruxism: How Teeth Grinding Damages the Jaw Joint

Bruxism — clenching and grinding, mostly during sleep — is the single most common driver of TMJ disorder we see. The forces involved are enormous: night grinding can exceed normal chewing force many times over, applied for hours with no rest.

Warning Signs You Grind

• Morning jaw soreness, facial fatigue, or temple headaches
• Flattened, chipped, or notched teeth; enamel wear your dentist keeps noting
• Tooth sensitivity without decay
• A partner who hears grinding at night
• Scalloped tongue edges or cheek ridges from pressure

How Grinding Becomes TMJ Disorder

The joint tolerates brief loads well. Sustained nightly compression inflames the joint capsule, degrades the cushioning disc, and trains jaw muscles into chronic overactivation — the full TMJ picture of pain, clicking, and restricted opening. Untreated, the damage is progressive: enamel does not grow back and disc damage compounds.

Treatment That Works

A drugstore boil-and-bite guard often makes grinding worse by giving the muscles a chewy target. Effective care is engineered: a custom occlusal guard designed from your bite records to decompress the joint, Botox for severe muscle overactivation, and T-Scan-guided bite adjustment when specific contacts trigger the clenching reflex.

When to See a TMJ Specialist

Grinding plus jaw pain is a progression warning — the earlier the intervention, the more tooth and joint you keep. Dr. Enrico DiVito has treated TMJ disorder in Scottsdale since 1980 using a non-surgical protocol: a structured exam, CBCT 3D imaging when indicated, custom oral appliance therapy, laser-assisted muscle treatment, and T-Scan-guided bite adjustment.
