Hi, I have a really bad toothache on a tooth that had a root canal about a year ago. The pain goes away for a minute if I swish with cold water but comes back just as bad after that. The pain feels the same as it did before I had the root canal and its stopping me from sleeping
Thanks for your query, I have gone through your query. The pain in the root canal treated tooth is because of the gum infection in the tooth, or it can be because of the improperly filled tooth. Nothing to be panic, consult an oral physician and get a radiograph done to confirm the diagnosis. If it is an improperly treated tooth, then it has to be retreated. If it is a gum infection, then get scaling and root planing done. Meanwhile you can take a course of antibiotics like amoxicillin and metronidazole combination. I hope my answer will help you, take care.
