Success for RCT is to remove all the bacteria and other pathogens from the root canal. Most studies have proven that using a laser in RCT to kill bacteria and other pathogens, is the most effective than a conventional method.
Laser technology also reduces possible side effects from the root canal procedure. There’s no need to worry about files breaking off or getting stuck in the canal. The Waterlase laser also limits the amount of bleeding during dental treatment, and can be used with minimal or no local anesthesia. Post-operative problems of traditional root canals are practically eliminated — the laser reduces the amount of inflammation, swelling and discomfort often felt as the anesthesia wears off. Patients may not even need pain medication often prescribed following dental surgery.
