Root canal therapy is a treatment to relieve dental pain and save your teeth. During this treatment an endodontist who specializes in such treatment removes the infection and protects the decontaminated tooth from future microbial invasion.
Usually a root canals procedure is almost painless treatment. That’s because dentists apply anesthetics, and the nerve is blocked from sending pain signals to the brain. A root canal is simply removing the nerve, cleaning the canal space, preparing the canal space and finally putting the root canal filling inside the root.
