Bruxism — night grinding and clenching — works the graveyard shift: you sleep through the whole performance while your jaw runs a masterclass in isometric overexertion. The morning-after signature is readable, the stress link is real, and the dentist has the hardware. The self-check, first.

The Morning Signature

The tells on waking: jaw muscles tired or tender (the masseter — cheek-side — worked all night), temple headaches with no other explanation, teeth sensitive without cavities, and the partner’s testimony (grinding is audible; sleepers deny it universally). Two or more: the suspicion has standing.

The Dental Evidence

The dentist reads the longer record: flattened tooth edges, chips and wear facets, scalloped tongue edges and cheek ridges (the clench’s soft-tissue witnesses). This is why the six-month chair matters — bruxism is usually DIAGNOSED there and suspected at home.

The Stress Connection

Grinding tracks stress and disrupted sleep closely — high-load seasons show up in jaws (the cortisol chapters strike again), and daytime clenching (the traffic-jam jaw, the deadline bite) trains the night habit. The daytime awareness cue: lips together, teeth APART — the resting jaw’s actual home position.

The Management Menu

The night guard is the standard hardware (custom beats boil-and-bite for committed grinders — it protects enamel from the habit while other measures address the habit itself), alongside the stress-and-sleep work, the pre-bed jaw massage and warm compress for tender mornings, and caffeine’s evening curfew (stimulants and grinding correlate). The teeth are not renewable; the guard is $300 of insurance on a set you can’t reorder.

Check the morning jaw, ask the dentist to read the edges, un-clench the daytime, guard the night. Bruxism bills quietly for years — the check costs one mirror moment, and the hardware costs less than one crown.
