Medications that cause teeth grinding
Bruxism or teeth grinding is repetitive jaw muscle activity characterised by clenching or grinding of the teeth, thrusting of the lower jaw. Bruxism occurs in adults and children, with an incidence of 18 % in adults. Consequences include jaw muscle enlargement, tooth wear and crack development, fractures of tooth restorations and pain associated with the teeth and jaw muscles.
Bruxism is an under recognised adverse drug reaction associated with use of antipsychotics and anti depressant, most commonly reported with fluoxetine, venlafaxine and sertraline, even after a few doses.
Teeth grinding, or bruxism, can be caused by a variety of factors, including stress, anxiety, and certain medications.
Some drugs that have been associated with causing teeth grinding include:
Selective serotonin reuptake inhibitors (SSRIs): These are a class of antidepressant drugs that can increase the risk of teeth grinding in some people.
Stimulants: Drugs like cocaine, amphetamines, and caffeine can all cause teeth grinding.
Antipsychotics: Certain antipsychotic medications like haloperidol and chlorpromazine have been associated with bruxism.
Ecstasy (MDMA): This drug is known to cause jaw clenching and teeth grinding, especially at higher doses.
Anti-anxiety medications: Some anti-anxiety drugs like benzodiazepines have been linked to teeth grinding.
If you are experiencing teeth grinding, it is important to talk to your doctor or dentist. They can help determine the underlying cause and recommend appropriate treatment options.
