Adderall and teeth grinding
Why Adderall causes teeth grinding and jaw clenching, what the damage looks like, and how to protect your teeth without stopping the medication.
Never start, stop, or change a medication based on what you read here. Bring questions to your dentist, physician, pharmacist, or prescribing clinician.
Quick answer
Adderall and similar stimulants frequently cause teeth grinding (bruxism) and jaw clenching, especially when the medication is active. This usually shows up as worn-down enamel on the back teeth, fractured fillings, jaw soreness in the morning, or headaches in the temples. The grinding does not always stop when you stop the medication, but the damage can be slowed dramatically with a custom night guard, daytime awareness, and managing the dry mouth that compounds the wear.
The mechanism
Why stimulants cause teeth grinding
Adderall is a CNS stimulant that increases dopamine and norepinephrine. These neurotransmitters affect movement and muscle tone, including the muscles that move the jaw. The result is a baseline increase in jaw muscle activity, which often shows up as clenching during the day and grinding at night.
Stimulants also cause dry mouth. Saliva is the natural buffer that protects enamel, and without it, the mechanical wear from grinding does more damage per hour than it otherwise would. The combination is what makes stimulant-related bruxism particularly destructive: more grinding, on enamel with less protection.
Most patients do not notice the grinding itself, because it happens during sleep or as a subconscious daytime clench. What they notice is the downstream effects: shortening of the front teeth, flat wear facets on the molars, fractured restorations, jaw muscle tenderness on waking, and headaches that radiate from the temples.
