Root canal treatment is mainly called as RCT. It is a simple and common treatment in dentistry. RCT is done when nerve of roots affected with decay or injury. In previous decade when tooth has large decay and broken down, only option was extraction means removal of tooth. But now we can save tooth by rct and prevent any need for bridge, denture and implant…prevention is better than replacement.
After RCT is tooth needs crown means cap to strengthen unsupported tooth structure.
