Now a days with the advent of technology Root canal treatment is a painless treatment. In most cases two sitting of 45 min each suffice. Avoid chewing from the side of Root canal treated tooth. Chew from the other side till you don't get a crown for the tooth.

Hello Root canal treatment is not a painful procedure as you will be on medication during and after that Mostly it's a two sitting procedure but those can be more if there is any infection You should not eat anything hard and sticky from that side And each sitting will be for atleast 40 minutes Do not worry it's a very simple procedure
