Biological dentistry is a practice philosophy emphasizing minimal use of materials considered potentially harmful, including metal amalgam, and a broader consideration of the oral-systemic health connection — though it is not a formally regulated dental specialty in the U.S.
Key takeaways
- —Biological dentistry is a philosophy, not a formally regulated specialty — what it means in practice varies by provider.
- —Common practices include mercury-free fillings, avoidance of metal restorations where possible, and zirconia implants as the preferred implant material.
- —Some biological dentists are members of organizations like IAOMT, which has specific training and accreditation standards.
- —Asking a provider exactly what their biological dentistry approach means in their specific practice gives you the most useful information.
What biological dentists typically emphasize
Practices commonly associated with biological or holistic dentistry include: using composite or ceramic materials rather than amalgam for fillings, favoring zirconia over titanium for implants where appropriate, avoiding fluoride in some cases, greater attention to biocompatibility of all materials used, and sometimes incorporating whole-body wellness considerations alongside conventional dental care.
Why the term is not uniformly defined
Because biological dentistry is a philosophy rather than a formally regulated specialty, the practices and priorities included under this label vary meaningfully between providers. Two dentists who both call themselves biological dentists may have quite different specific protocols — which is why asking directly about a provider's specific approach is essential.
What to ask when evaluating a biological dentist
Ask directly: what does your biological dentistry approach mean in practice? What materials do you use and avoid and why? Are you a member of any relevant professional organizations, and what standards does that membership require? These questions help you evaluate substance rather than accepting a label at face value.

Frequently asked questions
Is seeing a biological dentist necessary to get a zirconia implant?+
No — zirconia implants are offered by many providers across different practice philosophies, including conventional implant specialists. A biological dentist is simply more likely to routinely offer and prefer zirconia, not the only type of provider who can place it.
Is biological dentistry evidence-based?+
Some practices associated with biological dentistry have solid evidence behind them (like preferring tooth-colored fillings, or concern about metal sensitivity in implants); others are based more on philosophy or precautionary reasoning than on large controlled studies. Evaluating specific claims individually rather than accepting or rejecting the whole philosophy broadly is the most useful approach.
