Bruxism: Clenching and Grinding

Bruxism is the clinical name for clenching and grinding, and one of the most common drivers of temporomandibular joint disorder. It is worth separating into two conditions that get treated as one: awake bruxism, which is largely a habit tied to concentration and stress, and sleep bruxism, which is not a habit at all and does not respond to being told to stop.

01

Sleep bruxism is a sleep phenomenon

Grinding during sleep occurs in bursts of masticatory muscle activity, frequently clustered around brief arousals from deeper sleep. It is associated with sleep-disordered breathing, certain medications, caffeine, alcohol, nicotine and some neurological conditions. It is not something a sleeping person chooses, and it is not simply an expression of daytime stress — which is why willpower-based advice fails so consistently.

02

Why the airway connection matters

There is a well-documented association between sleep bruxism and obstructive sleep apnea. One plausible mechanism is that jaw and tongue muscle activity helps reopen a narrowing airway, meaning the grinding is partly protective. That association is exactly why a bruxism evaluation should ask about snoring, unrefreshing sleep and daytime fatigue — and why treating the teeth alone can miss the actual driver.

03

What the damage looks like

Flattened, shortened teeth; enamel worn through to the darker dentine underneath; small fractures and chipped edges; increased sensitivity; a ridge of bone along the inside of the lower jaw; scalloped tongue edges; and jaw muscles that are visibly enlarged. Many people are unaware they grind until a dentist points these out.

04

Treatment beyond protecting the enamel

A well-made appliance protects the teeth and, correctly designed, can reduce muscle load. But if sleep-disordered breathing is contributing, an appliance that only covers teeth does not address it — and some designs can worsen an airway. Where snoring or unrefreshing sleep is present alongside grinding, evaluating both together produces a better result than treating the wear alone.

Common questions

Can I stop grinding in my sleep?
You cannot consciously control it, and no treatment reliably eliminates it. What is realistic is reducing its intensity and consequences — protecting the teeth, lowering muscle load, and addressing contributors such as disrupted breathing, certain medications and evening stimulants.
Is grinding always caused by stress?
No. Stress is a genuine contributor to awake clenching, and it modulates sleep bruxism, but sleep bruxism has physiological drivers that stress alone does not explain. Treating it purely as a stress problem is the reason many people are told to relax and get no better.
