Dentist Not Required to Disclose Low Risk of Chronic Pain From Root Canal: B.C. Court of Appeal

Parhar was not asked to sign a consent form, but Weaver testified that he would have given a standard description of the procedure. Weaver did not advise Parhar of the possibility of chronic nerve pain, since it was not taught in dental school, nor had he encountered it in practice. After the procedure, Parhar’s pain intensified, which led to further procedures.
