Single Sitting Root Canal Treatment (RCT) is a modern dental procedure designed to save a severely decayed or infected tooth in just one visit. Unlike traditional multi-visit RCTs, this approach is quicker and more comfortable for the patient. It involves cleaning, shaping, and sealing the root canals in a single appointment, making it highly efficient while minimizing discomfort and the risk of reinfection. Single sitting RCT is ideal for patients with tight schedules or those seeking immediate pain relief without multiple dental visits.
