How is root canal therapy performed?
A small hole is made in the top of the tooth to access the center of the tooth where the nerve is (after numbing of course). The insides of the roots are then shaped and disinfected, removing any nerve tissue in the process. This accomplishes two things, removing the painful nerve, and disinfecting the infected tooth. The roots are then filled. The roots are NOT removed during the procedure, so you still have roots to anchor the tooth in your jaw.
