On wednesday I had the first half of a root canal. Tooth was drilled, antibiotic gel put in and a temporary filling fitting. Thursday started with a dull ache. Since Friday it's got progressively worse. Taken over counter tablets every 4 hours and haven't slept more than 2 hours at a time due to the pain. My face appears swollen and even with the taken tablets the pain never goes away. I also cant eat as biting down causes shooting pains. Is this normal or would it be okay to phone emergency dentist. Not sure I can last until my dentist opens 2moz.
