Lemme tell you about Northshore Endodontics– I needed two root canals and my regular dentist referred me to Dr. Sullivan. I previously had a root canal done a few years ago by a Tufts student in Boston. That, as you may have guessed, didn’t work out too well. Dr. Sullivan knows exactly how to properly numb your mouth so that you feel NO pain. At all. Nothing. I didn’t realize that you’re not supposed to feel pain because all my previous dental work was done without being properly numb(and I didn’t know to speak up). The kicker — he called me that evening to check on me! Who does that anymore? No, wait, another kicker — after the novocaine wore off I didn’t experience any soreness or pain. I was so excited and bragged about this experience to everyone at work the next day.
