Introduction
Dental amalgam fillings, commonly known as "silver fillings," have been used for over a century as a restorative material. These fillings are composed of approximately 50% mercury, mixed with other metals such as silver, tin, and copper. The ongoing use of dental amalgam fillings has sparked debate regarding potential health risks associated with mercury exposure. While amalgam fillings offer benefits like durability and affordability, concerns persist about the continuous release of mercury vapor and its potential effects on overall health, including weight management. This article aims to explore the existing research on amalgam removal and its correlation with weight loss and other health improvements.
Mercury Exposure from Amalgam Fillings
Mercury vapor is continuously released from amalgam restorations, with the rate depending on factors such as the number of amalgam surfaces, location, age, eating habits, and amalgam composition. Mercury is a known toxic metal, and when inhaled, approximately 80% is absorbed into the bloodstream and distributed to various organs. The central nervous system (CNS) is particularly vulnerable due to mercury's ability to cross the blood-brain barrier.
Potential Health Risks of Mercury Exposure
Mercury is cytotoxic, neurotoxic, immunotoxic, and nephrotoxic, potentially impacting the immune, renal, and nervous systems. Exposure to mercury may lead to various health issues, including:
- Mood changes
- Memory and concentration problems
- Headaches
- Fatigue
- Reduced hand steadiness
- Manual dexterity issues
- Cardiovascular problems
- Endocrine disruption
- Insomnia
- Respiratory problems
- Tremors
- Psychological issues
Conflicting Views on Mercury Exposure
There is ongoing debate about whether the level of mercury exposure from dental amalgam fillings is high enough to cause toxic effects. Some organizations, like the World Health Organization, suggest that there may be no safe threshold for mercury exposure. Others, such as the Human Biomonitoring Commission of the German Federal Environment Agency, argue that the level of mercury exposure from dental amalgam below a certain threshold does not pose a risk to health.
Research on Amalgam Removal and Health Outcomes
Several studies have investigated the effects of amalgam removal on various health outcomes. These studies often compare individuals who have had their amalgam fillings removed (treatment group) with those who have not (control group).

Urine Mercury Levels and Amalgam Fillings
Research indicates that individuals with dental amalgam fillings tend to have higher levels of mercury in their urine compared to those without. Removal of amalgam fillings has been shown to decrease urine mercury levels to levels comparable to individuals without amalgam fillings.
Impact on Self-Reported Symptoms
Studies have explored the relationship between amalgam removal and changes in self-reported symptoms. These symptoms often include sub-clinical measures of mental and physical health that are believed to be mercury-dependent.
One study conducted in Calgary, Canada, compared individuals who had their amalgam fillings removed with those who retained them. The results suggested that amalgam removal reduced the likelihood of self-reported symptom deterioration and increased the likelihood of symptom improvement.
Bergen Amalgam Trial
The Bergen Amalgam Trial, conducted in Norway, examined patients with medically unexplained physical symptoms (MUPS) attributed to dental amalgam. Participants in the Amalgam cohort had all their amalgam restorations removed and replaced with other dental restorative materials. The study found that the intensity of both local and general health complaints was reduced in the Amalgam cohort after amalgam removal.
Specifically, significant improvements were observed in symptoms such as:

- Taste disturbance
- Dry mouth
- Facial stiffness/paresthesia
- Cardiovascular complaints
- Fatigue
- Memory problems
- Difficulty concentrating
- Anxiety/depression
Additional Studies on Symptom Improvement
Other studies have also reported improvements in various symptoms following amalgam removal. These symptoms include fatigue, headaches, vision problems, depression, neurological issues, autoimmune issues, and worsening of pre-existing chronic conditions.
One study by Dr. Paul Engel, a Swiss dentist, demonstrated significant improvement in a number of health issues directly related to chronic mercury poisoning after amalgam removal. Linda Jones's study on individuals medically diagnosed with mercury poisoning revealed that the majority of those who underwent amalgam removal and mercury detoxification experienced enduring health gains.
DAMS (Dental Amalgam Mercury Syndrome) Project
The DAMS project evaluated over 1000 peer-reviewed and government studies, revealing mercury as a cause or major factor in over 40 chronic health conditions. They also reviewed over 60,000 cases of amalgam removal and replacement, showing evidence of cure or significant improvement in numerous chronic conditions.
Amalgam Removal and Weight Loss
While the direct link between amalgam removal and weight loss is not extensively researched, some studies and anecdotal evidence suggest a potential connection. Mercury toxicity can disrupt various bodily functions, including metabolism and hormonal balance, which can indirectly impact weight.
Potential Mechanisms Linking Amalgam Removal to Weight Loss
Improved Metabolic Function: Mercury exposure can interfere with metabolic processes, potentially leading to weight gain or difficulty losing weight. Amalgam removal may reduce mercury exposure, allowing the body's metabolic functions to normalize, which could contribute to weight loss.

Hormonal Balance: Mercury can disrupt the endocrine system, affecting hormones that regulate appetite, metabolism, and fat storage. By reducing mercury exposure, amalgam removal may help restore hormonal balance, potentially leading to weight loss.
Reduced Inflammation: Mercury can trigger inflammation in the body, which is linked to weight gain and metabolic disorders. Amalgam removal may lower the body's inflammatory burden, which could positively impact weight management.
Improved Overall Health: As demonstrated in numerous studies, amalgam removal can lead to improvements in various health symptoms, such as fatigue, headaches, and cognitive difficulties. These improvements may increase energy levels and motivation to engage in physical activity and healthy eating habits, indirectly contributing to weight loss.
Cautions and Considerations
It's important to note that weight loss is a complex process influenced by various factors, including diet, exercise, genetics, and overall health. While amalgam removal may contribute to weight loss in some individuals, it is not a guaranteed solution for weight management.
Safe Amalgam Removal Protocols
If considering amalgam removal, it is crucial to find a dentist who follows strict safety protocols to minimize mercury exposure during the procedure. These protocols typically include:
- Using a rubber dam to isolate the tooth being worked on
- Providing the patient with an alternative air source
- Using high-volume evacuation to remove mercury vapor and particles
- Cutting the amalgam filling into chunks to minimize mercury vapor release
- Using a mercury separator to prevent mercury from entering the wastewater system
SMART (Safe Mercury Amalgam Removal Technique) Protocol
The SMART protocol, developed by the International Academy of Oral Medicine and Toxicology (IAOMT), is a comprehensive set of safety measures designed to protect both the patient and the dental staff during amalgam removal. Dentists who are SMART-certified have undergone training in these techniques.
