Cayenne pepper.
You can call 111 to get an emergency appointment. But you can get orajel in boots/most supermarkets, numbs the area for a little bit. I feel for you, toothache is miserable, hope it gets sorted soon.
Clove oil or oragel. Put plenty on. Plus some good painkillers
Get a numbing throat spray and spray wherever hurts. It’s a temporary relief but anything helps! Also get so adult Ambesol.
