The Hidden Dangers of Mercury Fillings—and Why Safe Removal Matters
Uncovering the Hidden Dangers of Mercury Amalgam Fillings—and the SMART Way to Remove Them Safely
For decades, silver-colored dental fillings—technically known as amalgam fillings—have been the go-to solution for cavities. But what many people don’t realize is that these "silver" fillings contain up to 50% mercury by weight, a heavy metal with well-documented toxic effects on human health. Despite mounting scientific evidence and growing global concern, millions still carry mercury in their mouths, often unaware of the silent damage it may be causing.
In this blog, we’ll explore:

Symptoms that may be linked to mercury toxicity

What Are Mercury Amalgam Fillings?
Dental amalgam has been used since the 1800s and is composed of a mixture of metals, including mercury, silver, tin, and copper(1). Mercury is used because it binds the other metals together into a durable, moldable substance that hardens quickly. While amalgam fillings have been praised for their strength, they come with an invisible risk: mercury vapor release.
According to the World Health Organization (WHO), no level of mercury exposure is considered safe (2), especially when it comes to inhaled mercury vapor—which is exactly what amalgam fillings release during activities like chewing, brushing, and teeth grinding.
Mercury: A Potent Neurotoxin in Your Mouth
Mercury is one of the most toxic elements on the planet. It crosses the blood-brain barrier, lodges in tissues, and accumulates over time. Once in the body, it disrupts mitochondrial function, increases oxidative stress, impairs detoxification pathways, and causes widespread inflammation. (3)
Health Risks Associated with Mercury Fillings:
Neurological symptoms: brain fog, memory issues, anxiety, depression, tremors
Cognitive decline and dementia: chronic mercury exposure has been linked to an increased risk of Alzheimer’s disease and other neurodegenerative conditions.
Cancer risk: mercury contributes to oxidative DNA damage, impairs immune surveillance, and disrupts mitochondrial function—all of which may contribute to the development and progression of certain cancers.
Immune dysfunction: autoimmunity, chronic infections, hypersensitivities
Hormonal imbalances: thyroid dysfunction, adrenal stress, reproductive issues
Digestive problems: candida overgrowth, leaky gut, dysbiosis
Fatigue and mitochondrial dysfunction
Cardiovascular risk due to increased oxidative stress
Studies have even shown a correlation between the number of amalgam fillings and mercury levels in the brain and kidneys (4). And individuals with genetic detox pathway impairments (like MTHFR or GST polymorphisms) are at greater risk for mercury retention and toxicity (5).
Why Safe Removal Is Essential
Removing mercury fillings improperly can release large amounts of mercury vapor, temporarily increasing your exposure and burdening your detox pathways. That’s why it’s critical to choose a biological dentist trained in Safe Mercury Amalgam Removal Technique (SMART), as outlined by the International Academy of Oral Medicine and Toxicology (IAOMT) (6).
SMART Removal Protocol Includes:
Use of a rubber dam to isolate the tooth
High-volume suction and external air vacuum to capture vapors
Oxygen mask for the patient to avoid inhalation
Protective gear for the patient and dental team
Mercury absorbent rinses and chelating agents
Proper room ventilation and waste disposal
Functional Support After Mercury Filling Removal
Even when removed safely, residual mercury can remain stored in tissues. That’s why partnering with a functional medicine provider after removal is key for effective detoxification.
Post-Removal Detox Support May Include:
Binders: Activated charcoal, chlorella, or modified citrus pectin
Liver support: Milk Thistle and NAC
Glutathione: Liposomal form for antioxidant and detox support
Mineral repletion: Zinc, selenium, and magnesium to displace heavy metals
Mitochondrial nutrients: CoQ10, B vitamins, and alpha-lipoic acid
Infrared sauna and lymphatic drainage: To mobilize and excrete stored toxins
A functional medicine provider can also order lab testing (such as mercury challenge tests or porphyrin profiles) to assess your current toxic burden and tailor your detox plan accordingly.
Is It Time to Let Go of Mercury Toxins?
Mercury amalgam fillings were once considered “standard care,” but we now understand the long-term health risks they pose. Carrying mercury in your mouth is like living with a slow-release neurotoxin—especially harmful for individuals already dealing with fatigue, brain fog, autoimmunity, hormonal imbalances, or chronic illness.
If you’re considering mercury filling removal, don’t go it alone. It’s critical to work with a SMART-certified biological dentist and a functional medicine provider who can guide and support your detoxification process safely and effectively.
Your body—and your brain—will thank you.

Frequently Asked Questions About Mercury Fillings
Can mercury fillings cause health problems?
Yes. Mercury amalgam fillings release vapor that can accumulate in the body and contribute to neurological issues, immune dysfunction, hormonal imbalances, dementia, and even cancer. (7)
Is it safe to remove mercury fillings?
Yes—if done correctly by a biological or SMART-certified dentist using safety protocols to prevent mercury vapor exposure.
What is the SMART protocol?
SMART stands for Safe Mercury Amalgam Removal Technique. It includes specific steps like oxygen masks, rubber dams, and air suction systems to reduce mercury exposure during removal.
How do I detox after mercury filling removal?
Post-removal detoxification may include liver support (like Milk Thistle), binders (like chlorella or charcoal), glutathione, sauna therapy, and functional medicine-guided supplementation.
Do all dentists use the SMART protocol?
No. Only SMART-certified biological dentists follow these strict safety guidelines. It's essential to choose a dentist with this training for safe mercury removal.
