Root canal treatment is necessary when the nerve of a tooth is affected by decay or infection. When the motive is to save a tooth, pulp, nerves, and decay, bacteria get eliminated while the remaining area is filled and the tooth is restored. Many patients believe that removing a wisdom tooth or any other tooth that has problems is the solution, but what is not realised is that teeth replacement will ultimately be more costly and cause significant problems for adjacent teeth. Root canal treatment can help in repairing and saving a tooth that is extremely decayed. There is a high success rate for root canal treatment and it lasts for a lifetime but there might be cases when the tooth needs treatment again because of new infections.
