Bruxism is the repetitive clenching, grinding or rubbing of the teeth, occurring while awake or during sleep. This page outlines typical features, clues that suggest bruxism, and which specialists might help with assessment and follow‑up.
What bruxism is and who it affects
Bruxism refers to involuntary jaw-muscle activity that causes teeth to be clenched, ground or rubbed together. It can occur during sleep (sleep bruxism) or when awake (awake bruxism). Multiple factors often contribute: stress or anxiety, sleep disorders, bite or dental issues, and in some cases medical conditions or medications. Bruxism can occur at any age and varies widely in frequency and severity between people.
Common signs and oral health effects
Typical signs include worn or flattened tooth surfaces, increased tooth sensitivity, tight or sore jaw muscles, morning headaches, and clicking or limited movement in the temporomandibular joint (TMJ). Bed partners may report grinding noises at night. Over time, unchecked bruxism can damage restorations (fillings, crowns), increase tooth wear, and affect gum and jaw health; a dentist can evaluate these changes.
How it’s evaluated and which specialists to consult
Initial assessment usually begins with a dental exam to check tooth wear, restorations and jaw function. If bruxism appears linked to sleep problems, a sleep medicine specialist or sleep center may be recommended. When symptoms suggest obstructive sleep apnea (loud snoring, witnessed breathing pauses) coordination with ENT or sleep medicine may be needed. If stress or mental health factors are prominent, a psychologist or psychiatrist can support coping strategies. Neurology input may be considered for unusual neurological signs.
Management approaches and everyday measures
Aims of management are to reduce symptoms and limit dental or joint damage. Options considered by clinicians can include oral appliances, physical therapy for jaw muscles, and strategies to improve sleep hygiene and manage stress. Regular dental follow‑up helps monitor tooth wear and restorations. If sudden severe symptoms occur — for example inability to open the mouth, locking of the jaw, intense facial pain, or recent facial trauma — seek urgent medical or dental care.
