What biological dentistry actually is
Biological dentistry — also called holistic dentistry, integrative dentistry, or biocompatible dentistry — is an approach to dental care that considers the mouth's relationship to overall systemic health. Practitioners typically avoid dental amalgam, emphasize biocompatible restorative materials, may offer nutritional or detoxification support around procedures, and often follow SMART protocol for amalgam removal.
It is not a separately licensed specialty in the United States — biological dentists hold the same DDS or DMD credentials as conventional dentists. The term describes a philosophy and set of practices, not a formally regulated category of care.
How they compare
| Area | Biological Dentistry | Conventional Dentistry |
|---|---|---|
| Amalgam placement | Avoids; won't place new amalgam | May still place in some cases |
| Amalgam removal | SMART protocol or equivalent | Standard removal (variable) |
| Material selection | Emphasizes biocompatibility | FDA-approved materials (broad category) |
| Systemic health view | Oral-systemic connection central | Oral health focus primarily |
| X-ray approach | Often minimizes exposure; digital only | Standard protocols |
| Fluoride | Often avoided or minimized | Standard recommendation |
| Root canals | Some practitioners discourage | Standard procedure when indicated |
| Cost | Often higher | Typically lower or insurance-covered |
| Licensing | Same DDS/DMD credentials | Same DDS/DMD credentials |
| Evidence base | Variable — some strong, some weak | Extensive peer-reviewed foundation |
Where they overlap more than you'd think
The divide between biological and conventional dentistry is often overstated. Most modern conventional dentists also prefer composite to amalgam, use digital X-rays to minimize radiation, and follow evidence-based prevention protocols. The meaningful differences are concentrated in a few specific areas: amalgam removal protocol, fluoride philosophy, and attitude toward root canals and some other procedures.
For patients specifically seeking SMART-protocol amalgam removal, the relevant question is not "is this a biological dentist?" but rather "what specific safety measures does this dentist use?" — which you can ask any dentist regardless of how they categorize themselves.
Evaluating claims critically
Both sides of this conversation can overreach. Some biological dentistry claims — particularly around root canals causing systemic disease or amalgam causing specific named conditions — are not well-supported by current evidence. Conversely, some conventional dismissals of patient concerns about amalgam exposure during removal understate the legitimate rationale for protective protocol.
Choosing the right dentist for you
For amalgam removal specifically, the most important factors are protocol transparency and technical competence — not whether a dentist calls themselves "biological." Ask any prospective provider the specific questions from our appointment checklist, compare their answers to the SMART protocol criteria in our Mercury Safety Score explainer, and make your decision based on what they actually do.
