How to Become a Certified Dental Technician

Who May Become Certified?

All dental technicians who possess the required education and/or experience, have a working knowledge of the English language, and have not been found guilty of practicing dentistry illegally are eligible to become a Certified Dental Technician.

The Examinations

A candidate for certification must successfully complete three examinations, taken in any order, within a four-year period: a written comprehensive, a specialty practical, and a specialty written.

Recognized Graduates (RGs) have four years to take and substitute the RG examination for the comprehensive examination and pass the other exams (the written specialty and the practical exam) to become a CDT.

After four years, the RG would need to take and pass all three examinations to achieve the CDT status.

The six specialties to choose from are:

  • complete dentures
  • partial dentures
  • crown and bridge
  • ceramics
  • orthodontics
  • implants

The comprehensive examination has 160 multiple-choice questions and the specialty written examinations have 80 multiple-choice questions. The goal of the CDT examinations is to measure the mastery of knowledge and applied skills that are representative of the successful, professional practice of dental technology.

Candidates for CDT examinations must submit a completed application and payment for a specific examination. If approved, the candidate will be sent a confirmation postcard.

A list of scheduled examination dates and sites can be found on the CDT Testing Dates/Places page.
