To treat root cysts, firstly, root canal treatment of the affected tooth with cysts is required, secondly, thorough scraping of the cyst tissue under local anesthesia, and finally, apicoectomy of the cyst root tissue is required to completely treat the root cysts to prevent recurrence. Root canal treatment is about 400 RMB per root canal, scraping of periapical cysts is about 500 RMB, local anesthesia is about 50 RMB, and apicoectomy is about 330 RMB per root. Combined, the cost of periapical cyst surgery is about $1000 for treatment, and the cost will be higher if the cyst is too extensive.
