I’ve had a tooth extraction or two before. The following advice is based on my memory and experience with that kind of surgery and being poor. I’m not a doctor. It’s highly negligent for the surgeon to abandon you over the weekend after a surgery.
You may not need pain meds beyond ibuprofen (you can take more than the recommended dose on the bottle for a short time). Acetaminophen is useless for treating the swelling and dental pain in my experience. Continue your other after care while you figure this out: rinse with warm salt water regularly, avoid foods with seeds, no drinking through a straw, apply ice packs regularly at intervals to keep the swelling down (ibuprofen will help with this also), whatever else they advised. Keeping the swelling down with ice packs, ibuprofen, and drinking cold water will do way more for your pain than whatever pain meds they prescribed. Sometimes I’d just keep a big glass of ice water nearby and hold the ice cold water in my mouth.
You will absolutely need the antibiotics ASAP though! Call a doctor, any doctor, urgent care, ER, whatever you have to do to get the antibiotics. I wouldn’t even mention the pain meds. When I’ve taken those pain meds, they did nothing for the pain in my mouth, but they did mean I didn’t notice bumping into a table and cutting my leg badly. And there is the non-zero chance that as soon as you mention painkillers, you’ll be labeled as drug seeking. Stay focused on the antibiotics, that’s the important med. Oral infections can go from “Do I have an infection?” to life threatening emergency in a surprisingly short time.
It’s all about tense (past, present, future) and the idioms which leave out those implied verbs that indicate tense. You can still wish someone a good night as a form of greeting, but you’ll need to use those “extra” words to avoid the idiomatic expression. Saying good evening is just the common shortened idiomatic form.
