Learning has always been fundamental to our missions. It’s why our organization was founded in 1985 by Drs. Edward Arana and Gary Verigin. We focus on the HOW of biological dentistry – so you can provide your patients with comprehensive mouth/body care.

Certification shows that you have a well-defined knowledge base and understanding of treatment protocols in line with the broad concept of biological dentistry. Your certification badge stands as a kind of seal of approval.

Only those who have completed our certification process may call themselves “Certified Biological Dentists,” “Certified Biological Hygienists,” or “Certified Biological Dental Assistants.”

IABDM credentialing speaks volumes to the world as we continue to lead in the field of biological dentistry and medicine.

Certification for Dentists

In addition to confirming your knowledge of biological dentistry, certification gets your profile placed in our online directory of biological dentists. As of September 15, 2020, it will feature ONLY certified members.

We offer three levels of certification for dentists: Basic, Fellow, and Master.

Basic Certification

The first level of certification involves coursework, an online exam, and presentation of two amalgam removal cases to our education committee.
Access to the online version of our foundational course, Biological Dentistry 101, is included with your application fee.

The exam is designed as a learning experience. Each question includes resources and reading materials to educate you in biological dentistry. Topics covered include homeopathy, meridians, basics of mercury removal, fluoride, and cavitations.

Certification Requirements

For the case presentation, the candidate will submit before/after and pre-op radiographic images at least 48 hours before their presentation. Word, Powerpoint or standard image formats (e.g., .jpg, .gif, .bmp, .png) are acceptable. The candidate and examiner will meet via Skype to discuss the case. Points to be covered include

  • Pertinent medical history.
  • Dental status.
  • Your protocol for safe amalgam removal.
  • Any prep care you provide your patient.
  • Your office’s mercury-safe precautions.
  • Your own mercury hygiene activities (e.g., chelation, et al)
  • Health benefits that may have been attributable to the removal process.

Candidates for Fellowship need to be certified, have at least 3 years of IABDM membership, and have attended at least 3 meetings (annual or regional). You must also have taken a course in nutrition, such as our online course designed and taught by Dr. Al Danenberg.

You must also present a case study which must include a biological extraction, a research project or peer-reviewed article, and proof of 4 hours of community service.

Once you achieve Fellowship, you can get any staff members in your office certified for free.

Candidates for Mastership must be IABDM Fellows in good standing, with 5 years of membership in the Academy. You must prove you have taken a course in one of the following areas: homeopathy, airway or craniosacral therapy, or EAV or muscle testing, and present 2 more case studies of your choice.

You must also show proof of lecture experience – in an academic setting, online, at conferences, etc. This helps establish you as a teacher – one we would be proud to claim and help share the word.

Certification for Hygienists, Assistants, & Staff

Registered Dental Hygienists, Registered Dental Assistants, and office staff are encouraged to become certified to work in a biological dental office. You can earn your registration in four easy steps.

Step one: If you haven’t done so already, become a member of the IABDM. (Membership is not required for certification, but we certainly encourage it!)

Step two: Take our Biological Dentistry 101 course online or in person (offered at our annual meeting and occasionally at regional meetings) and view Barbara J. Green’s presentation “Myofunctional Therapy Assessment Protocol.” 

Step three: Take the written exam. Conceived as a learning experience, the exam is open book and will cover topics such as

  • Mercury, mercury toxicity, and mercury-safe dentistry.
  • Root canals, cavitations, and other oral foci.
  • Biological approaches to periodontal disease.
  • Oral manifestations of systemic health problems.
  • Fluoride.
  • Therapeutic ozone.

Step four: Do one of the activities below.

  1. Write an article about using natural approaches in an oral cavity and submit it to our education committee for review.
  2. Complete a small study and present it to our education committee via Skype.
  3. Do a PowerPoint case presentation about a patient that shows you thinking outside the box of a regular hygiene visit and submit it to our education committee for review.
  4. Do a video worthy of being on YouTube about a topic in biological dentistry. Be creative and make it fun!

Maintaining Certification

To maintain certification, you must stay current on your dues, show proof of at least 12 hours CE per year (in biological dentistry or medicine) and attend at least one IABDM conference every 2 years.
