What Is Bruxism?
Bruxism is the involuntary grinding or clenching of teeth, often occurring during sleep (sleep bruxism) or while awake (awake bruxism). It can damage teeth, cause jaw pain, and affect overall oral health.
Patients in Sydney commonly seek treatment for bruxism after noticing worn teeth, headaches, or jaw discomfort.
Causes of Bruxism
Stress and Anxiety
Emotional stress can trigger jaw clenching, often during sleep.
Sleep Disorders
Sleep apnea and other sleep disturbances increase grinding risk.
Abnormal Bite or Misaligned Teeth
Uneven teeth can force the jaw muscles to overwork.
Medications & Stimulants
Certain antidepressants, caffeine, and nicotine may worsen bruxism.
Lifestyle Factors
Alcohol use and recreational drugs may contribute.
Signs and Symptoms
Worn, chipped, or cracked teeth
Morning jaw pain or stiffness
Headaches, earaches, or neck pain

Jaw clicking or popping
Sleep disturbance for self or partner
Early recognition is key to preventing permanent dental damage.
