Reducing Exposure to Dental Toxins: A Practical Guide

When we think about health risks, dental materials aren’t usually the first things that come to mind. Yet the materials used in dental procedures can contain substances that may affect our overall health. As a dental health advocate, I believe patients deserve to be informed about potential toxins in dental materials and how to minimize exposure while maintaining excellent oral health.
This practical guide will help you understand common dental toxins, their potential health impacts, and concrete steps you can take to reduce your exposure without compromising your dental care.
Common Dental Toxins: What You Should Know
Several materials used in conventional dentistry have raised health concerns due to their chemical composition. Let’s examine the most common ones:
Mercury Amalgam Fillings
What they are: Often called “silver fillings,” dental amalgams contain approximately 50% elemental mercury combined with other metals like silver, tin, and copper. Despite their declining use, millions of people still have amalgam fillings in their mouths.
Potential concerns: Mercury is a known neurotoxin that can release small amounts of vapor during chewing, brushing, or grinding. According to research published in the Journal of Occupational Medicine and Toxicology, mercury vapor can be absorbed into the bloodstream and may accumulate in organs including the brain and kidneys.
The U.S. Food and Drug Administration (FDA) has acknowledged potential risks for certain high-risk groups, including:
- Pregnant women and their developing fetuses
- Women who are planning to become pregnant
- Nursing women and their newborns
- Children, especially those under six years old
- People with neurological disorders
- People with kidney dysfunction
- Those with known sensitivity to mercury or other components of amalgam
Bisphenol A (BPA) in Composite Fillings
What it is: BPA is a chemical used in many plastic products, including some composite (white) dental fillings and sealants. It’s used as a building block in dental resins.
Potential concerns: BPA is an endocrine disruptor that can mimic estrogen in the body. Research published in the Journal of Dental Research has found that some composite fillings can release BPA, particularly immediately after placement. Studies have linked BPA exposure to various health issues, including:
- Reproductive system abnormalities
- Increased risk of certain cancers
- Metabolic disorders like obesity and diabetes
- Cardiovascular problems
- Neurological effects
Fluoride in Dental Materials
What it is: Fluoride is added to many dental products, including some fillings, cements, and preventive treatments, due to its ability to strengthen tooth enamel and prevent decay.
Potential concerns: While fluoride in appropriate doses is beneficial for dental health, excessive exposure has been linked to dental fluorosis (discoloration and pitting of tooth enamel) and, in very high doses, skeletal fluorosis. Some research also suggests potential neurological effects from high fluoride exposure, though this remains controversial.
Nickel and Other Metals in Orthodontics and Crowns
What they are: Metals like nickel, chromium, and cobalt are commonly used in orthodontic appliances, crowns, and bridges.
Potential concerns: These metals can cause allergic reactions in sensitive individuals. According to the American Contact Dermatitis Society, nickel is the most common contact allergen in developed countries, affecting approximately 10-20% of the population.
Practical Steps to Reduce Your Exposure
Now that we understand the potential concerns, let’s explore practical steps to minimize exposure to dental toxins:
1. Discuss Material Options with Your Dentist
What to do: Before any dental procedure, have an open conversation with your dentist about the materials they plan to use.
Questions to ask:
- “What materials do you recommend for my fillings/crowns/etc.?”
- “Do these materials contain mercury, BPA, or high levels of fluoride?”
- “What biocompatible alternatives are available?”
- “What are the pros and cons of each option in my specific case?”
Why it matters: Many dentists now offer biocompatible alternatives but may not discuss them unless specifically asked. Being proactive empowers you to make informed decisions.
2. Consider Safe Amalgam Removal (If Applicable)
What to do: If you have existing amalgam fillings and are concerned about mercury exposure, consult with a dentist who follows the Safe Mercury Amalgam Removal Technique (SMART) protocol developed by the International Academy of Oral Medicine and Toxicology (IAOMT).
Key SMART protocol elements:
- Use of a rubber dam to isolate teeth
- High-volume suction with mercury filters
- External air supply for the patient
- Protective gowns and face shields for all present
- Chunking and sectioning techniques to minimize mercury vapor
- Thorough rinsing and cleaning after removal
Why it matters: Improper removal of amalgam fillings can actually increase mercury exposure temporarily. The SMART protocol minimizes this risk.
Important note: The FDA and other health organizations do not recommend removing structurally sound amalgam fillings solely due to concerns about mercury content. The removal process itself can release mercury vapor and damage tooth structure. This decision should be made carefully in consultation with your healthcare providers.
3. Request BPA-Free Dental Materials
What to do: Ask your dentist specifically for BPA-free composite materials. Several options are now available, including:
- Diamond Crown and Diamond Flo
- Venus Diamond and Venus Pearl
- Admira Fusion
- Grandio
- Certain products from the Filtek line
Why it matters: Studies have shown that initial BPA exposure is highest immediately after placement of certain composite fillings. BPA-free alternatives can eliminate this exposure while still providing durable, aesthetic restorations.
4. Consider Ceramic Alternatives
What to do: For larger restorations like crowns, inlays, and onlays, consider ceramic materials like:
- Lithium disilicate (e.g., IPS e.max)
- Zirconia
- Porcelain
Why it matters: These materials are generally biocompatible and free from common dental toxins like mercury, BPA, and nickel. They also provide excellent durability and aesthetics.
5. Minimize Metal Exposure in Orthodontics
What to do: If you need orthodontic treatment, discuss these options with your orthodontist:
- Ceramic brackets instead of metal
- Titanium appliances (for those with nickel sensitivity)
- Clear aligner systems (like Invisalign), which are typically made from BPA-free materials
Why it matters: These alternatives can reduce exposure to potentially allergenic metals while still effectively straightening teeth.
6. Support Your Body’s Natural Detoxification
What to do: While reducing exposure is primary, supporting your body’s natural detoxification processes may also help:
- Stay well-hydrated with filtered water
- Consume foods rich in antioxidants (colorful fruits and vegetables)
- Ensure adequate intake of minerals like zinc and selenium
- Consider adding cilantro, chlorella, or other natural detoxifying foods to your diet
Why it matters: These approaches may help your body process and eliminate toxins more efficiently, though they should not be considered a substitute for reducing exposure.
