Short answer: I'd skip it, and not just for the "don't take other people's prescriptions" reason — sertraline and tramadol have a genuine interaction.

Why this pairing is a problem

• •Serotonin syndrome risk. Tramadol isn't just an opioid; it also blocks serotonin reuptake. Stacked on 100 mg of sertraline, that raises the risk of serotonin toxicity — agitation, confusion, sweating, shivering, fast heart rate, muscle twitching or stiffness, diarrhea, fever. It's uncommon but can be serious, and usually starts within hours of a dose.
• •Seizure risk. Tramadol lowers the seizure threshold on its own, and SSRIs add to that.
• •It may not even work well. Tramadol is a prodrug — your liver has to convert it via the CYP2D6 enzyme into the compound that actually relieves pain. Sertraline inhibits CYP2D6. So you can end up with poor pain relief while still carrying the serotonergic and seizure risk. Worst of both worlds.

What actually works better for dental pain

Ibuprofen plus acetaminophen together outperform opioids for dental pain in head-to-head trials. A typical regimen is ibuprofen 400 mg with acetaminophen 500–1000 mg every 6 hours (respecting the daily limits on each, and assuming you have no kidney, ulcer, liver, or bleeding issues). One caveat: SSRIs plus NSAIDs modestly increase GI bleeding risk, so keep ibuprofen short-term, take it with food, and mention it to your pharmacist if you have any stomach history or take a blood thinner.

The bigger issue

Severe tooth pain usually means pulpitis or an infection, and painkillers only buy time — the pain comes back until the tooth is treated. If you have facial swelling, fever, trouble swallowing, or the swelling is spreading toward your eye or under your jaw, that's urgent care or an ER today, not a wait-and-see.

Your pharmacist can check this whole picture for free in a two-minute conversation, including anything else you take. Worth doing before you swallow anything from a friend's bottle.
