What is the duty of a dentist to disclose to a patient?

A dentist is under the same duty to disclose as a medical doctor. He has a duty to make disclosure of material risks, including special or unusual risks, involved in the contemplated procedure. The nature and scope of the duty was described by Laskin C.J.C. in his judgments in Reibl v. Hughes, 1980 CanLII 23 (SCC), [1980] 2 S.C.R. 880, and Hopp v. Lepp, 1980 CanLII 14 (SCC), [1980] 2 S.C.R. 192 [[1980] 4 W.W.R. 645]. He said in Reibl at p. 884: It is now undoubted that the relationship between surgeon and patient gives rise to a duty of the surgeon to make disclosure to the patient of what I would call all material risks attending the surgery which is recommended. The scope of the duty of disclosure was considered in Hopp v. Lepp [1980 CanLII 14 (SCC), [1980] 2 S.C.R. 192], at p. 210, where it was generalized as follows: "In summary, the decided cases appear to indicate that, in obtaining the consent of a patient for the performance upon him of a surgical operation, a surgeon, generally, should answer any specific questions posed by the patient as to the risks involved and should, without being questioned, disclose to him the nature of the proposed operation, its gravity, any material risks and any special or unusual risks attendant upon the performance of the operation. However, having said that, it should be added that the scope of the duty of disclosure and whether or not it has been breached are matters which must be decided in relation to the circumstances of each particular case."
