Risk factors

These factors increase your risk of bruxism:

• Stress. Increased anxiety or stress can lead to teeth grinding. So can anger and frustration.
• Age. Bruxism is common in young children, but it usually goes away by adulthood.
• Personality type. Having a personality type that's aggressive, competitive or hyperactive can increase your risk of bruxism.
• Medications and other substances. Bruxism may be an uncommon side effect of some psychiatric medications, such as certain antidepressants. Smoking tobacco, drinking caffeinated beverages or alcohol, or using recreational drugs may increase the risk of bruxism.
• Family members with bruxism. Sleep bruxism tends to occur in families. If you have bruxism, other members of your family also may have bruxism or a history of it.
• Other disorders. Bruxism can be associated with some mental health and medical disorders, such as Parkinson's disease, dementia, gastroesophageal reflux disorder (GERD), epilepsy, night terrors, sleep-related disorders such as sleep apnea, and attention-deficit/hyperactivity disorder (ADHD).
