Short answer: I'd avoid it. Tramadol is one of the more problematic opioids to combine with sertraline, and there's a better option for tooth pain anyway.

Why this specific pairing is a poor match

• •Serotonin toxicity risk. Tramadol isn't just an opioid — it also blocks serotonin and norepinephrine reuptake. Stacked on top of 100 mg of sertraline, that raises the risk of serotonin syndrome (agitation, sweating, tremor, muscle twitching or stiffness, racing heart, diarrhea, fever, confusion). It's uncommon but well documented with exactly this combination.
• •Seizure risk. Tramadol lowers the seizure threshold on its own, and SSRIs add to that.
• •It probably won't work well. Tramadol is a prodrug — your liver has to convert it via CYP2D6 into the metabolite that actually relieves pain. Sertraline inhibits CYP2D6. So you get less pain relief and more of the parent drug that drives the serotonergic side effects. Worst of both ends.
• •Separately: taking a friend's opioid means no dose guidance, no interaction check, and no accountability if something goes wrong.

What actually works better for dental pain

Good evidence shows that ibuprofen combined with acetaminophen outperforms opioids for acute dental pain. A common regimen is ibuprofen 400–600 mg plus acetaminophen 500–1000 mg together every 6 hours (staying under 3000 mg/day acetaminophen and following the ibuprofen label). Skip this if you have kidney disease, ulcers, are on blood thinners, or have another reason to avoid NSAIDs — worth a quick check with a pharmacist, who can also confirm it against your full med list for free.

Cold compress on the cheek, sleeping with your head elevated, and avoiding very hot/cold/sweet foods on that tooth also help.

The real fix is the tooth. Painkillers don't touch the cause — usually an inflamed pulp or an abscess — and that won't resolve on its own. Call a dentist for an urgent appointment; many have same-day emergency slots, and dental schools or community health centers are cheaper options if cost is the barrier.

Go to urgent care or the ER now if you have: facial or jaw swelling, swelling under your jaw or in your neck, trouble swallowing or breathing, inability to open your mouth fully, fever, or swelling spreading toward your eye. Those suggest a spreading infection that needs antibiotics and drainage promptly.

If pain is severe and unmanaged, call your prescriber or an on-call dentist — they can choose something safe alongside sertraline rather than you guessing with a leftover pill.
