Recently I required root canal and when  the doctor began to use the file, the pain was intence and unbearable, even after several more injections.  This has not been a issue in the past, so why now? I have been drinking alot more than usual could this be a contributing factor in the novacaine not having any effect in me what so ever, I'm scheduled to go back in for some more work, I really don't think I can bear that kind if intence pain!

 

regards,
