What is a pulp pump like?

Dental pulp is the nerve of teeth, which is mainly used for nerve nutrition supply and sensory nerve. Once inflamed or exposed, it is generally difficult to repair itself. Taking medicine is very difficult to treat pain and the effect is not good. Therefore, it is generally recommended to do root canal therapy, that is, remove the tooth nerve, diminish inflammation, disinfect, then fill it with drugs, and then fill the crown. Root canal therapy mainly uses instruments, that is, pulp pulling needle and an instrument for removing residual substances from root canal wall, but without dental nerve.
