The cost of root canal therapy is not fixed, and it has a certain relationship with the teeth treated by root canal and the hospital chosen. Usually, the cost of dental treatment for a single tooth is about 6~9 yuan. If the patient's root canal treatment is double teeth or premolars, the cost usually needs about 12 yuan to 16 yuan. If the teeth treated are more complicated, including 3-4 root canal teeth, the cost will reach 2,-2,5 yuan. In addition, the hospital chosen by patients also has a certain impact on the price. Some regular large hospitals usually have higher prices and better treatment effects.

our first step in root canal therapy is to grind the teeth, which means that we call it an exposure of the pulp cavity after grinding, so that all the root canals of the teeth are exposed after the pulp cavity is exposed, and then all the pulp in all the root canals are pulled out by pulp pulling technology. After pulling out, we can see that it passes through the root canal orifice, and then use a file of the root canal, such as manual or organic. Then there are many files made of nickel and titanium, and then the root canal can be thickened to achieve a preparation before filling, and a root canal measurement is needed after the preparation before filling. Therefore, when preparing the root canal, the root canal with a relatively straight lamp and a relatively thick root canal is actually relatively simple to prepare, but there are some relatively curved or even thin root canals, so its preparation process is more complicated, and the length of each root canal should be measured after the root canal preparation. Prepare for future root canal filling. After root canal preparation, perform root canal disinfection. That is to say, we will kill some bacteria in the root canal by drugs. After killing, we will fill a root canal last time, and the prepared root canal will be completely filled with gutta percha. In this way, root canal treatment will be completed.
