The cost of root canal treatment is charged according to the whole course of root canal treatment and is mainly determined by the number of root canals the patient needs to treat. There are two main types of root canal filling materials available in the clinic, one is cold adhesive filling and the other is hot adhesive filling. The cost of a cold cement filling is relatively low, perhaps only about$300-400 for a single root canal, and about$800-1000 for 3-4 root canals in posterior teeth. The cost of hot glue filling is relatively dense and the material is relatively better, so the cost charged will be higher. Clinically, if a single root canal is filled with hot glue, about 800 yuan may be charged for one root canal, and for 3-4 root canals of posterior teeth, the cost is relatively higher if hot glue filling is used, which may reach 1800 yuan or even 2000 yuan.
