For dental practices, consent for an examination is implied. This is not required to discuss or document unless the patient has questions or concerns. Any further work must be explained in addition to the risk factors, materials being used, and the treatment itself. Before starting the treatment, they will need to provide consent. For most of the time, consent can be provided verbally with dental procedures. For complex procedures, information sheets are recommended.
When it comes to more complex procedures such as surgery, a verbal consult will likely not be adequate. In these scenarios, written consent is almost always obtained. For example, consent, where anesthesia is used, will typically require written consent.
