Short answer: I'd avoid it, and there's a better option for tooth pain anyway.

Why the combination is a concern

• •Serotonin syndrome. Tramadol isn't just an opioid — it also blocks serotonin reuptake, like sertraline does. Stacking them raises the risk of serotonin toxicity. It's uncommon with a single dose, but it's a real interaction that prescribers usually try to avoid or monitor closely.
• •Seizures. Tramadol lowers the seizure threshold, and SSRIs do too. The combination increases that risk, especially at higher tramadol doses.
• •It may not even work well. Tramadol is a prodrug — your liver has to convert it (via the CYP2D6 enzyme) into the metabolite that actually relieves pain. Sertraline inhibits that enzyme. So you can end up with weaker pain relief while still carrying the serotonergic and seizure risk.

Also, you don't know the dose or strength of what your friend gave you, and taking someone else's prescription opioid isn't something I'd recommend regardless.

What actually works better for dental pain

Ibuprofen plus acetaminophen, taken together, outperforms opioids for acute dental pain in head-to-head trials. A typical regimen is ibuprofen 400–600 mg with acetaminophen 500–1000 mg every 6 hours (staying under 3000 mg/day of acetaminophen, and skipping ibuprofen if you have kidney disease, ulcers, or are on blood thinners). Cold compress on the cheek, sleeping propped up, and avoiding very hot/cold/sweet foods also help.

The bigger issue

A "bad tooth" that hurts enough to reach for opioids usually means an infected pulp or abscess — and painkillers won't fix that. You need a dentist, likely for a root canal, extraction, or drainage, possibly with antibiotics. Many areas have emergency dental clinics or dental schools that take same-day patients.

Go to an ER or urgent care now if you have facial or jaw swelling, swelling near your eye or spreading down your neck, fever, difficulty swallowing or breathing, or trouble opening your mouth. Those suggest a spreading infection, which can become dangerous quickly.

If you're in enough pain that OTC options aren't cutting it, call your prescriber or a dentist — they can pick something that's safe alongside sertraline.
