The real tasks — a full meal, a long conversation, and the guarded yawn that stops a lock.
A wide unguarded yawn is a common trigger for locking. Support the chin with a fist when you feel one coming.
Two weeks of softer food while the muscles settle is a dose change, not a permanent diet.
Continuous gum chewing loads the jaw muscles for hours. Stopping it is one of the fastest wins available.
Three couplets · two rounds · twelve minutes · a jaw that rests
Fist under the chin; open as if yawning while the fist limits the range — never unguarded.
Easier smaller opening · Harder less support
Open with the fist under the chin as a permanent limit, then close under control.
Easier more support · Harder less support
Chew steadily as though eating a meal, alternating sides, for the whole minute.
Easier softer food · Harder firmer food
Something firmer, five seconds a side, twelve times — the last stage of chewing tolerance.
Easier softer · Harder firmer
Speak or read aloud continuously; check every fifteen seconds that the teeth are apart.
Easier shorter bouts · Harder longer
While doing something demanding — a puzzle, a task — check and release the jaw.
Easier simpler task · Harder harder task
