YG - poor you. I really sympathise.
I've just finished my 8TH lot of antibiotics in the space of 3 months(all to do with dental abcesses, infections etc). I feel completely wiped out and just seem to be getting everything.
(((cyberhug)) to you, Hope you can get to the dentist fast and get sorted, but as you say, it will be another round of antibiotics first no doubt.
