Bruxism, or nocturnal teeth grinding, affects about 8-10 percent of adults. It causes jaw pain, headaches, tooth damage, and disrupted sleep. Causes are varied: stress, sleep apnea, lifestyle factors, medications. Here is what causes it and the proven solutions.

Signs you grind your teeth

Morning jaw pain or stiffness
Headaches, especially temple pain
Worn, flat, or chipped tooth surfaces
Increased tooth sensitivity
Sleep partner reports grinding sounds
Earaches without ear problems
Disrupted sleep without obvious cause

What causes bruxism

Stress and anxiety: The most common cause. Cortisol and tension trigger jaw clenching during sleep.

Sleep apnea: Bruxism is strongly linked. The body grinds in response to airway obstruction events. See sleep apnea signs.

Caffeine and alcohol: Both worsen grinding. Especially evening intake.

Smoking: Nicotine is a stimulant. Linked to higher bruxism rates.

Certain medications: SSRIs (antidepressants), Adderall, and other stimulants can trigger grinding.

Malocclusion: Misaligned bite. Can be addressed with orthodontics or dental work.

Solutions ranked by effectiveness

Solution	Effectiveness	Cost
Custom dental night guard	Best	300-800 (often covered by dental insurance)
Mail-in custom night guard	Very good	125-200
OTC boil-and-bite night guard	Good for mild	25-65
Stress management or therapy	Addresses root cause	Varies
Botox in masseter	Effective for severe	500-1,000/session
Address sleep apnea	Critical if apnea is the cause	See doctor

OTC vs custom night guards

OTC guards (25-65 dollars) are fine for occasional or mild grinders. Custom guards (mail-in 125-200 or dental 300-800) are required for moderate to severe grinders. See night guard comparisons.

Lifestyle changes that help

Cut caffeine after 2pm. Limit alcohol, especially evening. Manage stress (meditation, exercise, therapy). Address jaw tension with daytime awareness. Maintain consistent sleep schedule.

When to see a doctor

If grinding is causing tooth damage, persistent headaches, jaw pain affecting daily function, or if you suspect sleep apnea is involved. A dentist can prescribe a custom night guard and refer you to a sleep specialist if needed.
