Short answer: I'd avoid it — this is a combination that carries real risk, and taking a friend's opioid isn't a safe way to manage a toothache.

Why the combination is a concern

• •Serotonin syndrome. Tramadol blocks serotonin reuptake in addition to acting on opioid receptors. Adding it to sertraline can push serotonin levels too high. It's not common, but it happens, and it can be serious.
• •Seizure risk. Tramadol lowers the seizure threshold on its own, and SSRIs add to that effect.
• •It may not even work well for you. Sertraline inhibits the liver enzyme (CYP2D6) that converts tramadol into the metabolite responsible for most of its pain relief. So you may get weaker pain control while still carrying the serotonergic and seizure risk — the worst of both worlds.
• •Shared medication. You don't know the actual dose, and there's no one monitoring you. Opioids also aren't a great choice for dental pain in the first place.

Better options for dental pain

Ibuprofen (e.g., 400 mg) combined with acetaminophen/paracetamol (e.g., 500–1000 mg) taken together is, in head-to-head studies, more effective than opioids for dental pain — and it targets the inflammation that's actually causing it. Follow package dosing, and skip ibuprofen if you have kidney disease, ulcers, are on blood thinners, or have been told to avoid NSAIDs.

The real fix is dental care. A bad toothache usually means decay, a cracked tooth, or an infection — painkillers just buy time. Call a dentist and mention it's urgent; many clinics hold same-day slots for pain.

Seek same-day/emergency care if you have: facial or jaw swelling, swelling spreading toward your eye or down your neck, fever, trouble swallowing, opening your mouth, or breathing. Those suggest a spreading infection.

If you've already taken it, watch for: agitation or confusion, shivering, sweating, racing heart, muscle twitching or jerking (especially in the legs), overactive reflexes, fever, or diarrhea. Those developing within hours warrant urgent medical attention.

If your pain is severe and you truly need something stronger, your dentist or doctor can pick an analgesic that's safe alongside sertraline — there are options that don't interact.
