Meanwhile I just went back to my dentist to get a cleaning and a filling fixed. I have bad anxiety from growing up with a Dentist who could be described as Jigsaw from the saw movies. My current dentist has nitrous, which is a game changer for me. He also has hardcore numbing cream before the shot, and he also uses a two shot method, the first one is initial numbing that doesn't last long but also doesn't burn as much. And the second after that is full strength but by that time thanks to the gas and the first shot and the numbing cream I can't feel.
