bad toothache

I’m currently having a terrible toothache and I feel like I’ve tried all the possibilities to ease it. I called my dentist on Friday, but they have absolutely no openings until JUNE OF NEXT YEAR. 🙄 Ridiculous. I’ve tried every otc medicine. I have applied clove oil twice. But I can’t pinpoint which tooth/teeth it is. The pain is radiating to my upper jaw and causing some slight ear pain. What else can I do?? I don’t really want to go to the ER, but I’m feeling like that is my only option at this point. Any advice?
