I am scheduled for a root canal in a few days. I have a hole in a molar that got infected and now have an abscess. I have just finished my antibiotics. Tonight within ten minutes I went from normal everyday no pain to oh my God I feel like someone is slowly ripping my tooth out. It lasted for about an hour then the tooth had a rather prominent pop and then throbbing and pulsing inside the tooth for roughly ten seconds, then the pain eased. This has gone on for a few hours now, the pain increasing to almost unbearable tearing pain to a pop and release. Is this normal? Should I go back to the dentist or wait until after the root canal like scheduled? Is this something I should be worried about?
