I got root canal done in 2 sittings. The 2nd sitting was on Sept 1, 2012 and have called for capping to be done on this thursday (Sept 13). Though after first sitting I didn,t experienced any pain or discomfort, but 2 days after the 2nd sitting, I m feeling pain and discomfort in surrounding area (For 2 days I was prescribed Esgipyrin). What is the reason? Can I continue with Esgipyrin till my next sitting? Moreover, I feel rough and uneven surface at the back of my tooth which is very annoying when felt with tongue . What is the reason for the rough surface? Will it be overcomed by capping?
