It is funny how myths can escalate and it is even more prevalent in the world of dentistry, and once a myth has been created, it can be very difficult to dispel. One such treatment that always had the problem as being a bit of a monster is root canal treatment. People in the city of Leeds still believe that this is a truly horrible and frightening thing to have done, and to be fair, historically it could be. The process involves breaking into the tooth to remove the pulp and roots that have been infected by severe tooth decay. This could be very difficult using a traditional drill and sometimes, to ensure that the entire root is removed, it meant cutting through the gum tissue and attacking the tooth from the side. Then once the tooth had been filled, the gums would require stitching- and this was very painful afterwards. Of course, today, this procedure is simple to perform thanks to the use of lasers. But unfortunately, the legacy of the myth remains and it probably will take a long time before people start trusting this treatment.
