The root canal therapy's purpose is to remove the pulp (vessels and nerves inside the tooth), and ultimately the aseptic and hermetic seal of the teeth roots. This procedure takes place with the use of small tools, called files (needles), or rotary NiTi files which are supported in a special handpiece. The entire procedure is completed usually in 2-3 visits, or even in 1 at our dental clinic. Endodontics are essentially engaged in the treatment of the intense pain of a tooth (pulpitis), that is contaminated with bacteria.
