Illegal Practitioners

Use of the Restricted Title

In Ontario, any individual using the restricted titles “Dental Technologist”, “Registered Dental Technologist”, a variation or abbreviation (RDT), or an equivalent in another language must be registered with the College. Using these titles without being registered is illegal.

The Practice of Dental Technology

The practice of dental technology is defined as the design, construction, repair or alteration of a dental prosthetic, restorative or orthodontic device (crowns, bridges, implants, dentures, etc.). The practice of dental technology is limited to:

  • Members of the College of Dental Technologists of Ontario (CDTO) holding a General Certificate of Registration;
  • Members of the Royal College of Dental Surgeons of Ontario (RCDSO);
  • Individuals supervised by a member of CDTO holding a General Certificate of Registration; or
  • Individuals supervised by a member of RCDSO.

It is illegal for an individual who does not fall under the above categories to practice dental technology in Ontario.

CDTO Inactive Certificate of Registration

Members of the College who hold an Inactive Certificate of Registration are not permitted to practise dental technology in Ontario, however, can use the restricted titles dental technologist, Registered Dental Technologist, or the designation RDT.

Illegal Practice

You are encouraged to report any suspicions of individual(s) using the restricted titles or practising dental technology illegally. Please contact the Coordinator of Professional Conduct at 416-438-5003 to make a report or for more information.

The Public Register can be used to verify if an individual is registered with the College and can use the restricted title, and the Class of Certificate of Registration they hold to determine if they can practice dental technology.

The College takes allegations of illegal practice seriously and investigates all reports. Where there is sufficient information to support allegations of illegal practice regarding Members, it is dealt with through the College’s complaints process. Illegal practice of individuals who are not members of the College are dealt with through the Ontario court system.
