And so will the rest of your body. Bad teeth can lead to all sorts of health problems. The good news is that dental technology has changed a lot in the last ten years. The local anaesthetics are much, much better than they used to be. I’ve had four root canals in the last year (long story, but trust me: you need to see a dentist NOW), and none of them was more painful than getting a new filling. Just more time consuming. Find a dentist you like: don’t be afraid to interview them before opening your mouth in the chair.
