I am hoping I could get a little insight on this topic. About two weeks ago I went in for my 2nd root canal. My first root canal was about two years ago on my #18 tooth. Recovery took about a week and didn't have any lasting issues. My 2nd root canal was done on my #31 tooth and I am having some post numbness. Several hours after my root canal the Novocain wore off and I could feel everything. Took some pain killers for a few days to help. Three days later I woke up to some numbness on the right side of my lower lip. Throughout the week the numbness spread to my chin and the lower gums in the general area. I spoke to the oral surgeon and he told me that is perfectly normal and not to worry about it and that the numbness should subside soon As much as I trust my oral surgeon I would still like to get a 2nd opinion on this to put my mind at ease. I appreciate anyone's thoughts on this.
