The cost of a dental root canal treatment depends on the state of the nerve of the treated tooth. If the treated tooth lesion encroaches on the nerve, root canal treatment is required. The fee for root canal treatment is calculated based on a single root canal, i.e. the higher the number of root canals, the higher the fee. Root canal treatment mainly includes root canal irrigation, root canal preparation, root canal priming, use of special instruments for root canals, preparation of root canals for retreatment, root canal filling, etc. Each of these items has a fee schedule. Most anterior teeth are one root canal and cost between$500-600. Anterior molars can be one root canal or two root canals and cost around$800. Molar teeth have more root canals, three root canals or four root canals are possible, and the cost is between$800-1500. If you add the microscope, ultrasonic instruments, and machine enlargement equipment nowadays, the fee will be higher, and the cost of these equipment together will make the whole root canal treatment cost between$1500-1800. However, this fee is limited to some areas, and on a national scale, it may be around 4500 RMB in first-tier cities in China. Overall, the cost of a root canal treatment for one tooth is probably between$500-2000.
