Endodontics is a branch of dentistry that deals with dental pulp. Dental pulp consist of blood vessels, lymph vessels, nerves and connective tissue. When pulp gets inflammated it is presented as tooth ache. The tooth needs to be cured so it can remain in the jaw and not be extracted. The tooth is cured by extracting the infected pulp out of the tooth, cleaning and disenfecting root canals and filling them with artificial material. The treatment can be done manually or with a sofisticated machine. Such a sofisticated machine ensures more precision and enables the treatment to be done in only one visit.
