A root canal is a procedure done to save a tooth from extraction. A dentist who performs a root canal cleans out and seals the root and the pulp. The part of the nerve that is damaged is removed so that it cannot create further infection throughout the tooth. A root canal generally involves several steps which may or may not occur across multiple visits. These includes X-rays, the cleaning of the tooth, the sealing of the tooth and possible follow-up with a crown.
The advantage of a root canal done overseas is the enormous savings. A root canal performed in a country like Thailand, Hungary, Mexico or Costa Rica can cost one-third to one-tenth what it does in the United States. Medical facilities often cater to visitors from abroad.
