Let me start with the sentence that matters most, because I do not want it buried at the bottom: do not stop or change an antidepressant on your own. Not after reading this. Not after reading anything.

Good. Now we can talk.
 

The thing a lot of patients do not know

Certain medications, including some SSRI and SNRI antidepressants, have been associated with increased clenching or grinding in some people. Sertraline is one example reported in the dental and medical literature. It is not the only one.

This is not fringe. It shows up in the literature, and it comes up in dental offices more than you'd guess — usually by accident, when a patient mentions in passing that the grinding started "sometime last spring," and last spring happens to be when their prescription changed.
 

What this does NOT mean

It does not mean everyone taking sertraline or another antidepressant will develop bruxism. Most people will not. It does not mean these medications are bad — for a lot of people they are genuinely life-changing, and untreated depression and anxiety carry consequences that dwarf a worn molar. It does not mean you should white-knuckle it and stop taking something that is helping you. I want to be extremely clear about that, because health articles have a talent for making people do impulsive things.
 

What it does mean

Timing is information.


If your clenching or grinding started — or noticeably worsened — after beginning a medication or after a dose change, that timing is worth mentioning, to both your dentist and the healthcare professional who prescribed it. Not as an accusation. As a data point. Prescribers generally want to know about side effects. It's difficult for them to weigh something they were never told about.
 

Why saying something actually helps

Sometimes simply recognizing a possible connection changes what your healthcare team considers next. There may be options. There may not be — sometimes the medication is clearly worth it and the answer is to protect the teeth and move on. That's a legitimate outcome too. But that decision belongs to you and your prescriber, made with complete information — not to you alone at 11 p.m. with a search bar.
 

Meanwhile, protect the teeth

Whatever the cause turns out to be, grinding does the same thing to enamel. If you are grinding, the protection conversation is worth having in parallel — not instead of talking to your prescriber, but alongside it.
