Root canal therapy is the most basic in oral therapy, which needs the doctor's meticulous work. After all, the work of root canal therapy is invisible to patients, unlike other plastic surgery, which can directly see the appearance. If it is not done well, its problems will be delayed for a long time, and we can't just look at the cost decision. Generally, the number of roots is charged, and each root is charged between 200 and 300, which is more in line with the doctor's work.
