To treat the infected tooth, root canal treatment is needed and the bacteria causing the infection need to be removed.
The pulp is taken out from inside the root canals, which are then thoroughly cleaned and filled to prevent any further infection. The procedure normally involves two or more visits to your dentist. If your tooth is particularly difficult to treat your dentist may refer you to a specialist endodontist.
The success rate of root canal treatment is considerably positive. About nine out of ten cases a tooth can survive for up to 10 years after root canal treatment
