Had my root canal treatment for my lower molar tooth cavity 2days back and having ketorol DT 10mg tablet twice a day, but pain is still there around the root canal treated tooth. But doctor told me that the debris in the cavity has been removed and now the tooth is dead so u can't feel any pain even on touching the tooth so the pain may be due to some tissue or nerve touching near that root of the tooth. I'm in confusion and irritated with the pain all the day. Even painkiller not helping .
