Dental root canal treatment for the whole tooth will need a total of 1000 ~ 5000 yuan, the specific price is recommended to consult the local hospital. The cost of dental root canal treatment mainly depends on the number of root canals to be treated. Generally, incisors, cuspids, mandibular first premolar, maxillary and mandibular second premolar are single root canals, maxillary first premolar is usually double root canals, and molar has more root canals, which may be 3~4 canals. If the patient wants to treat the whole tooth, the doctor should first determine the number of specific root canals to be treated, and the general cost will be in the range of 1,000~5,000 RMB, but the specific price is not uniform, so it is recommended to consult the local hospital. Root canal treatment is suitable for patients with pulpitis, apical periodontitis, and exposed pulp, and can treat pulp necrosis and root infection. It is recommended that patients undergo the treatment in a timely manner when needed to avoid aggravation of the infection and more serious damage.
