Sertraline and teeth grinding
Why SSRIs like sertraline can cause teeth grinding, what the dental signs look like, and how to manage bruxism without stopping your antidepressant.
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
Yes, sertraline and other SSRIs can cause or worsen teeth grinding. The link is well documented but tends to be less severe than with stimulants like Adderall. Patients often notice morning jaw soreness or chipped teeth a few weeks to months after starting the medication. The grinding usually does not require stopping sertraline; a night guard, hydration for dry mouth, and sometimes a small dose adjustment are the typical levers.
The mechanism
Why SSRIs can cause teeth grinding
Sertraline works by increasing serotonin signaling. Serotonin also plays a role in how the brain controls jaw muscles, particularly the motor pathways involved in chewing and clenching. Increasing serotonin appears to disinhibit some of these pathways in a subset of patients, leading to involuntary clenching or grinding.
The grinding pattern from SSRIs is often nocturnal and goes unnoticed by the patient. Bed partners sometimes hear it before the patient feels anything. The dental signs are similar to stimulant grinding: flat wear facets on the cusps, chipped front teeth, fractured fillings, and jaw muscle soreness.
SSRI-related grinding tends to appear within weeks to months of starting the medication, and sometimes resolves on its own as the body adjusts. For patients in whom it persists, the same combination of saliva (which sertraline also reduces) and grinding is what makes the wear progress. Managing both protects the teeth.
