Clenching involves holding the teeth together with force and may occur while awake or during sleep. Some people also brace the jaw without obvious tooth contact. You might first notice tired facial muscles, morning soreness, or repeated awareness that the teeth are pressed together during concentration. Those clues are useful, but they do not prove that clenching explains every headache, toothache, or jaw symptom.
Assessment considers the pattern of activity and any effects on teeth, restorations, muscles, and joints. The plan may combine awareness strategies, management of specific dental damage, and an appliance when there is a clear protective purpose. It should also consider other causes of pain and relevant sleep or medical concerns. Permanently changing the bite is not a routine solution for jaw symptoms attributed to clenching, and a guard should not be presented as a guaranteed way to stop the behaviour.
