A Guide to CDA Services in BC

This document from the College of Dental Surgeons of BC explains how CDA services are governed under the CDSBC bylaws - as well as the conditions that must be in place in order to perform them.

Key points:

  • The services a CDA can perform will depend on the type of certification they hold and whether the service is considered a 'restricted activity', which means it poses a higher risk and can be performed only by a professional to whom government has granted authority.
  • It is the dentist's responsibility to delegate only to a person they know is competetent to perform the service. It is the CDA's responsibility to provide only the services they have the knowledge, skills and competency to perform.

Please view the document to find out about practices that are not restricted, must be delegated by a dentist, or must be supervised by a dentist.
