Bruxism (Teeth Grinding)

A parafunctional activity characterized by the involuntary clenching or grinding of the teeth. It can occur during sleep (Sleep Bruxism) or while awake (Awake Bruxism).

Why It Matters

Chronic bruxism applies excessive force (up to 250 lbs) to the teeth, leading to enamel attrition (wear), cracked teeth, gum recession, and Temporomandibular Joint (TMJ) disorders.

Clinical Details

• Signs: Flat occlusal surfaces (wear facets), abfraction lesions (notches at the gum line), and hypertrophy of the masseter muscles.

FAQ

What is bruxism?

It is the habitual, non-functional grinding of teeth.

What causes bruxism?

Etiology is multifactorial, including stress/anxiety, sleep disorders (like sleep apnea), malocclusion (misaligned teeth), and certain medications (SSRIs).

How to stop bruxism?

While stopping the habit is difficult, the damage is managed using a custom-fabricated Night Guard (Occlusal Splint) which prevents tooth-to-tooth contact. Botox injections into the jaw muscles can also reduce force.
