The root of the problem
ROYAL AIR FORCE LAKENHEATH, England - (Photo through a microscope) Gutta percha, a common root filling material, is inserted to fill the canals. Prior to filling, root canals are cleaned to prevent re-infection of the canals and to provide a seal. Root canal treatment addresses diseases of the pulpal tissue inside the tooth and roots.
