The cost of a root canal is usually $400 to $2,000, depending on the location of the tooth, the provider, and the region. Root canal treatment, also known as “killing the nerve”, is the most thorough treatment for endodontic disease and is the last barrier to preserving the tooth. Root canal treatment consists of three steps: root canal preparation, root canal disinfection, and root canal filling. These three steps make up a course of treatment, which usually requires patients to come in two to three times before the treatment is complete. For anterior teeth, there are fewer root canals, so the cost is lower ranging from $400 to $700, while for posterior teeth, there are more root canals and they are more complex, so the cost is higher ranging from $1,200 to $2,000. Overall the cost of root canal treatment will vary from tooth to tooth, from medical institution to medical institution, and from region to region, the specific price can be consulted with the local hospital, and the specifics need to be consulted with the local medical institution.
