Program Overview

At the Institute for Functional Dentistry (IFD), we believe hygienists are the frontline diagnosticians of modern health. This program transforms how you see the body, the mouth, and your role in preventing chronic disease.

Track 2 is designed specifically for dental hygienists and periodontal-focused clinicians, who want to expand beyond traditional periodontal care and lead the oral-systemic movement with confidence, clinical precision, and purpose.

This program builds a comprehensive foundation in functional medicine as it applies to hygiene, integrating systems biology, root-cause thinking, and whole-body oral health strategies that reshape prevention, periodontal management, and patient engagement.

Who Is This For?

This program is for hygienists and periodontal-focused clinicians who want to practice at the leading edge of oral-systemic medicine. It is ideal for:
Dental Hygienists
Periodontal-focused clinicians
Oral Hygiene Enthusiasts
Preventive Health Coaches working in dental settings

Hygienists today face unprecedented pressure to manage disease without understanding its systemic origins. Functional dentistry restores purpose, expands scope, and reconnects clinicians to the “why” behind whole-body prevention.

The IFD Difference

Our residency-style curriculum ensures you develop a full-spectrum skill set, integrating functional medicine and functional dentistry at a depth unlike any hygiene program.

You will learn a systems-based framework rooted in the principles of Functional Medicine, adapted specifically for the hygiene profession.

Integrated Functional Medicine Training

This program establishes a foundation in functional medicine principles,
paired with IFD-led case integration sessions.

Participants begin with a core clinical curriculum, supported by structured IFD integration sessions that translate systems-based concepts into oral-health–specific application.

Specialized IFD Modules

This program explores hygiene-specific content, including 
advanced oral microbiome mapping, root-cause periodontal protocols
and functional patient coaching.

Functional Learning Series

You will complete dental-specific modules addressing environmental contributors to

periodontal disease and oral-systemic health, including toxic exposures,

biotransformation pathways, and inflammatory burden.

Detailed Curriculum Breakdown

The Functional Hygiene program provides targeted, high-impact training
that integrates seamlessly with functional medicine frameworks.

You will learn to identify root-cause drivers of oral inflammation, understand whole-body contributors to periodontal disease, and apply upstream prevention in daily clinical care.

Our motto is

#Mouth Matters| #Spit for Science| #Bridge the Gap


Join thousands of clinicians transforming the way they understand, diagnose, and address oral-systemic health.

“Dentistry involves more than teeth; it includes craniofacial growth, jaw position, and tongue posture. These factors directly influence airway anatomy and function, which in turn affect breathing and sleep. This is why functional dentistry is essential to overall health.”

- Patrick Mckeown, MA, FRSB

“The mouth is not separate from the body. Functional dentistry bridges oral and systemic health by asking ‘why’ and working as a collaborative clinical team to identify the systemic root causes such as airway health, nutrition, digestion and absorption, hormone balance, and the microbiome, so we can create care that is preventive, personalized, and truly whole-body.”

- Meghan Barnett, MS, CNS
“Functional dentistry traces problems back to their actual drivers: airway dysfunction, microbiome dysbiosis, salivary chemistry, hormonal balance, systemic stress. It’s time to foster oral health that doesn’t need constant intervention, and the IFD is a phenomenal resource for those looking to achieve that balance. Functional dentistry redefines dentists as frontline clinicians in chronic disease prevention and healthspan optimization.”

- Ilon Choai, DDS, MS

Continuing Education Disclosure:

Continuing education (CE) credit for the Institute for Functional Dentistry (IFD) Certification Program is awarded on a module-by-module basis in accordance with AGD PACE guidelines. All IFD courses are self-paced and didactic; no hands-on clinical training is included. Each CE-eligible module consists of required educational components, which may include self-instruction lectures and associated assessments. Completion of all CE-eligible components and the module evaluation is required to earn CE credit. Case studies, integration sessions, and discussion-based learning experiences are included for educational enrichment but are designated as non-CE activities. Participants are encouraged to seek additional hands-on training and clinical mentorship before applying new techniques in patient care settings.

The IFD curriculum is structured as a sequential program. Modules must be completed in order (Module 1 through Module 6). Each module builds upon foundational concepts introduced in prior modules. The learning platform is configured to enforce this order, subsequent modules will remain locked until prior modules are successfully completed. This structure ensures all participants enter each stage of the curriculum with the appropriate preparation.

All IFD courses are didactic and self-paced in format. They do not include live patient interaction, supervised clinical practice, or hands-on procedural training. Completion of this course does not confer clinical competency to perform procedures. Participants are advised to supplement didactic learning with appropriate clinical training, mentorship, or supervised hands-on practice before incorporating new techniques into patient care. It is the professional and ethical responsibility of each licensed practitioner to assess their own clinical readiness prior to applying new skills in a patient care setting.
