Fantastic! I was in for a broken tooth (molar) repair. And I was worried about the novocaine injection which was the first thing. Worried for nothing. Dr. Covan numbed the gum first before the injection, and it really was just a little bit of a pinch feeling. Amazingly, afterwards, I did not even have any residual pain at the injection site. And everything was over within 30 minutes, in and out!
