My dentist said she would do a minor filling without one to see how I get on, as I might not need one for my root canal fillings if I need any of them done. However what I am confused about is I thought dentists are only allowed to local anesthetics these days. Also I would bloody well hope they do a local if I need any route canal fillings doing! I need a lot of work doing to my a few of my front teeth, they either need removing or a route canal filling doing and a new crown.
