The idea of “biological dentistry,” sometimes referred to as “holistic dentistry,” has been trending online for a while now. You may have seen ads for biological dentistry or heard friends talk about a new provider who practices it. More and more people today are focusing on holistic wellness, so dentistry that promises safer treatment options that are just as effective as traditional dental care are becoming more popular. 

But, trends aren’t always based on science. So, what exactly do biological dentists do? And is biological dentistry something you should look into? 

What is Biological Dentistry?

According to The International Academy of Oral Medicine and Toxicology (IAOMT), an organization of dentists, physicians, and researchers who have studied non-toxic dentistry extensively, biologic dentistry is “a philosophy that can apply to all facets of dental practice and to health care in general: to always seek the safest, least toxic way to accomplish the mission of treatment, all the goals of modern dentistry, and do it while treading as lightly as possible on the patient’s biological terrain.” 

In general, biological dentistry focuses on reducing exposure to potentially harmful substances that have been traditionally used in dental materials, such as mercury. Biological dentists believe that a healthy mouth is the gateway to overall health, and that reducing exposure to harmful substances makes for a healthier body. 

What Are Some Practices That Biological Dentists Follow, and How Do They Differ from Traditional Dentistry?

While general dentistry’s main focus is on oral health, holistic dentistry has a strong emphasis on how dental care and oral health affect the rest of the body. Some of their core practices include:

Mercury-Free Fillings

Biological dentists believe that amalgam fillings create measurable mercury exposure in patients, and that chronic exposure to mercury increases the risk of physiological harm. Instead of amalgam, they prefer using composite resin, porcelain, glass ionomer, and gold as non-toxic options in new fillings.  

While all dentists follow careful protocol when removing or replacing amalgam fillings, the IAOMT developed the Safe Mercury Amalgam Removal Technique (SMART) to minimize exposure to mercury vapor during the removal process:

• Both patients and staff wear specialized protective equipment
• The fillings are removed in rooms with HEPA filtration
• The patient is given an alternate source of air to breathe during the procedure
• The dentist uses a “rubber” dam and continuously removes saliva beneath the dam as the filling is removed, preventing any particles from being ingested
• Some holistic dentists also recommend nutritional supplements such as activated charcoal or chlorella, before or after the procedure to help the body detoxify 

Many traditional dentists are also going the mercury-free route, however, the FDA, the International Association for Dental, Oral, and Craniofacial Research, and the American Dental Association have stated that amalgam fillings are still safe and effective. Yes, mercury is a toxic substance on its own, but the mercury in amalgam fillings is bound to the other metals. Research shows that these fillings only leak very small amounts of mercury vapor that are far lower than daily recommended levels. 

No Fluoride

Although there is conflicting evidence on whether fluoride is good or bad for teeth, biological dentistry believes fluoride poses enough bodily harm to be omitted from dental care altogether. They cite concerns that fluoride causes skeletal fluorosis, reduced IQ in children, and endocrine disruption, and that all of those risks outweigh the benefits of stronger teeth. Instead, they strive to educate patients on how to prevent decay with proper hygiene practices.

Many traditional dentists continue to use fluoride, particularly in areas that do not have a fluoridated water system or whose residents can’t afford fluoridated toothpaste. They believe evidence is not conclusive enough that fluoride causes physical or cognitive problems. Instead, they side with the American Academy of Pediatrics on the benefits of strengthening children’s enamel with fluoride to prevent decay, and continue to site evidence that fluoride is also important for preserving the health of adult teeth.  

Personalized Biocompatibility

Rather than treating patients the same across the board, biologic or holistic dentists recognize that individuals vary in biochemical and immunological responses. For instance, a patient who suffers from allergies, an autoimmune disease, or an environmental sensitivity might have a different reaction to metals than someone who has no underlying conditions. Discussing and testing for these reactions ahead of dental procedures can make for a safer and more pleasant experience in the dental office. 

Clinical Nutrition

While biological dentists do not act as nutritional therapists themselves, they have knowledge of how nutrition impacts oral health as well as overall health. For instance, nutrient-dense foods that contain calcium, vitamin D, vitamin C, phosphorus, and protein can lead to stronger teeth, healthier gums, and a better immune system – and a stronger immune system can reduce systemic toxicity derived from mercury exposure.    

Does Becoming a Biological Dentist Require Special Certification or Training?

Unlike the 12 recognized dental specialties, biological dentistry is not regulated. All practitioners who learn about holistic dentistry, dental toxicology, and environmental safety and incorporate these practices into patient care can claim to be biological dentists. 

However, the IAOMT requires extensive coursework and exams to become a Certified Biological practitioner. Advanced certification for Fellowship and Mastership Biological Dentists require candidates to present case studies, conduct research projects, attend meetings, and meet other stringent criteria.  

Long story short: All dentists can make suggestions about the benefits of biological dentistry, but only members of the IAOMT are considered certified in the field. 

Should I Be Looking for a Holistic Dentist?

If you are interested in alternative medicine and are concerned about the toxicity of fluoride or mercury, a holistic dentist may be a good choice. They are licensed and trained just like every other dentist, but can also provide nutritional recommendations, alternative techniques, and natural remedies. If you have a chronic condition or allergies to conventional dental materials, they can make a careful plan to ensure your medical needs are met.
