Root canal therapy is simply a filling inside of a tooth’s root. Root canal procedures are performed when the nerve of the tooth becomes infected. During a root canal procedure, the nerve and pulp is removed, and the inside of the root is cleaned and then sealed. The procedure may require one or more office visits and the final step may involve further a restoration of the tooth (i.e. a crown). Dr. Boudreau treats many of his patients that require root canal therapy, however, there are circumstances when it is necessary to refer the procedure to one of the dental specialists in the area who has extensive training in this treatment.
