Introduction
Choosing a mercury free dentist means choosing safer, healthier dental care.
More than a century has passed since dentists began using mercury amalgam fillings, sometimes called “silver fillings,” because of their low cost and extended longevity.
The evidence that these fillings, which contain mercury, may be harmful to health is mounting, though. Thankfully, Colleyville has dentists who offer modern, mercury-free options that are better for your body and your smile.
Learn about the risks of mercury amalgam fillings, the effects they may have on your health, and how to replace them safely with the assistance of a mercury-free and mercury-safe dentist.
First let’s understand what are mercury amalgam fillings.
What Are Mercury Amalgam Fillings?
Mercury amalgam fillings are a mixture of metals used to fill cavities in teeth. The composition typically includes:
| Metal Component | Percentage | Purpose |
|---|---|---|
| Mercury | 50% | Binds other metals together |
| Silver | 22–32% | Provides strength |
| Tin | 14% | Increases durability |
| Copper | 8% | Enhances strength and corrosion resistance |
| Zinc | 2% (sometimes) | Extends shelf life |
People are worried about the safety of these dental fillings because mercury is poisonous, even though they are used a lot.
Mercury is a strong neurotoxin that can turn into a gas at room temperature. This gas can be breathed in and taken into the bloodstream.
How Mercury Vapor is Released
Mercury vapor doesn’t just sit dormant in your mouth. Various everyday activities can increase mercury release from amalgam fillings:

Why Mercury-Free and Mercury-Safe Dentistry Matters
Given the potential health risks, many health professionals are recommending individuals to seek out mercury-free and mercury-safe dentists.
These practitioners prioritize patient safety by avoiding the use of mercury amalgam fillings and employing specialized techniques to safely remove existing ones.
The Difference Between Mercury-Free and Mercury-Safe
It’s important to understand that these terms mean different things:

The Dangers of Improper Amalgam Removal
During the removal of amalgam fillings, you are greatly exposed to mercury vapor. Without proper precautions, drilling into the filling can release significant amounts of mercury vapor, which can be inhaled and absorbed into the body. It is necessary to select a dentist who is well-versed in the correct methods for the safe removal of amalgam.
What Can Go Wrong During Improper Removal
-
Mercury vapor levels can increase 100–1000× during drilling
-
Without proper protection, both patients and dental staff may inhale toxic fumes
-
Mercury particles can be swallowed during the procedure
-
Surrounding oral tissues may absorb mercury
-
Long-term health consequences may develop over time
The Health Risks of Mercury Amalgam Fillings
More than a hundred health issues are linked to the mercury vapor that is released by amalgam fillings, according to studies. Here are some of the most significant concerns:
1. Heart Disease
Mercury exposure has been linked to cardiovascular problems, including high blood pressure, atherosclerosis, and an increased risk of heart attacks.
Mercury can damage blood vessels and disrupt the body’s antioxidant defenses, leading to inflammation and oxidative stress.
Cardiovascular Effects of Mercury:
- Increases blood pressure by damaging blood vessel walls
- Raises LDL (bad cholesterol) levels
- Promotes plaque formation in arteries
- Disrupts heart rhythm regulation
- Reduces the body’s natural antioxidant protection
2. Autoimmune Diseases
Conditions such as fibromyalgia and Multiple Sclerosis (MS) have been associated with mercury toxicity.
Mercury can trigger autoimmune responses by altering the immune system’s ability to distinguish between foreign invaders and the body’s own tissues.
Common Autoimmune Conditions Linked to Mercury:
- Lupus
- Rheumatoid arthritis
- Hashimoto’s thyroiditis
- Scleroderma
- Chronic inflammatory conditions
3. Chronic Fatigue Syndrome (CFS)
Mercury’s impact on mitochondrial function can lead to chronic fatigue, as it disrupts the body’s energy production processes.
Energy Production Issues: Mercury damages the part of our cells that makes energy (mitochondria), leading to low energy and constant tiredness.
Inflammation and Stress: Mercury causes the immune system to stay active all the time, using up energy and making you feel drained.
Nerve Problems: Mercury affects how the brain and nerves work, messing up signals that control energy and leaving you feeling exhausted.
4. Allergies
Mercury can sensitize the immune system, making individuals more prone to allergies and hypersensitivity reactions.
Allergy-Related Symptoms:
- Skin rashes and eczema
- Respiratory issues
- Food sensitivities
- Chemical sensitivities
- Metallic taste in the mouth
5. Neurological Problems
Mercury is very damaging to the nervous system. It has been linked to depression, memory loss, anxiety, and fine tremors. Mercury can cross the blood-brain barrier, causing damage to brain cells and impairing cognitive function.
Neurological Symptoms of Mercury Exposure:
| Symptom Category | Specific Effects |
|---|---|
| Cognitive | Memory loss, difficulty concentrating, brain fog, confusion |
| Mood | Depression, anxiety, irritability, mood swings |
| Motor | Tremors, muscle weakness, coordination problems |
| Sensory | Numbness, tingling, vision problems, hearing loss |
| Sleep | Insomnia, restless sleep, nightmares |
6. Autism, Learning, and Developmental Disorders
While the link between mercury and autism is still debated, some studies suggest that mercury exposure during critical developmental periods may contribute to learning and developmental disorders.
Populations at Higher Risk:
- Pregnant women (mercury crosses the placenta)
- Nursing mothers (mercury transfers through breast milk)
- Children under age 6
- Women of childbearing age
- Individuals with genetic detoxification impairments
7. Kidney and Liver Damage
Mercury accumulates in the kidneys and liver, two organs critical for detoxification. Over time, this can lead to:
- Reduced kidney function
- Protein in urine
- Liver enzyme elevation
- Impaired detoxification capacity
- Increased susceptibility to other toxins
8. Reproductive Health Issues
Mercury exposure has been associated with:
- Reduced fertility in both men and women
- Irregular menstrual cycles
- Decreased sperm quality and motility
- Increased risk of miscarriage
- Hormonal imbalances
Modern Alternatives to Mercury Amalgam
Today’s mercury-free dentists offer several superior alternatives:

Safely Replacing Your Amalgam Fillings
If you’re considering replacing your mercury amalgam fillings, it’s essential to take the following steps to minimize your exposure to mercury vapor:
1. Find a Mercury-Safe Dentist
Look for a dentist who is certified in safe amalgam removal techniques. These dentists use specialized equipment, such as high-volume suction and rubber dams, to prevent mercury vapor from being released during the procedure.
Questions to Ask Your Dentist
- Are you trained in SMART or IAOMT protocols?
- What protective equipment do you use during amalgam removal?
- Do you use an amalgam separator?
- Can you provide references from patients who have had amalgam removal?
- What alternative filling materials do you recommend?
2. Prepare Your Body for Detoxification
Before amalgam removal, consider working with a healthcare provider to support your body’s natural detoxification processes. This may include taking supplements like selenium, zinc, and vitamin C, which can help bind and eliminate mercury from the body.
Pre-Removal Preparation (2–4 Weeks Before)
- Selenium: 200 mcg daily (helps protect against mercury toxicity)
- Zinc: 30 mg daily (supports immune function)

- Preserving more of your natural tooth structure
The Science Behind Mercury Toxicity
Understanding how mercury affects your body can help you make informed decisions:
How Mercury Enters Your Body from Amalgam Fillings
1. Vapor Inhalation (Primary Route)
- Mercury continuously vaporizes from amalgam fillings
- Approximately 80% of inhaled mercury vapor is absorbed through the lungs
- Once inhaled, it travels directly into the bloodstream and crosses into the brain
2. Ingestion
- Mercury particles worn off from fillings can be swallowed
- Absorbed through the digestive tract
- Less efficient than inhalation, but still a meaningful exposure pathway
3. Direct Absorption
- Oral tissues can absorb mercury directly
- Gum tissue is particularly permeable, allowing mercury to enter local circulation
What Happens Once Mercury Is in Your Body
- Distribution: Mercury circulates through the bloodstream to every organ, with the highest concentrations found in the kidneys, liver, and brain
- Accumulation: Mercury has a biological half-life of roughly 50–90 days, meaning elimination can take months or even years
- Binding: Mercury binds to sulfur-containing proteins, disrupting normal enzyme and protein function
- Cellular Damage: It damages mitochondria (the cell’s energy producers) and weakens cell membranes
- Elimination: Slowly excreted through urine, feces, sweat, hair, and nails
