Do I Need A Root Canal?
Can an X-Ray show if a tooth is dead and needs a root canal?
Dentistry: Root canal work not so bad after all. Root canal work is not as bad as people think when compared to other dental procedures. Self-reporting of their dental health suggests that patients find the procedure no worse than other dental work which overturns the popular belief that root canal work is the most unpleasant dental treatment.
