Is Mercury in Fillings Still a Concern?

Mercury has been used in dental fillings — often called amalgam fillings — for over a century. Despite their durability, concerns about mercury exposure have never fully gone away. Even today, many patients wonder: Are these fillings safe?

What Are Amalgam Fillings?

Amalgam fillings are made from a mix of metals, including mercury, silver, tin, and copper. Mercury makes up about 50% of the material, binding the metals together to form a stable, long-lasting filling.

While dental organizations like the American Dental Association maintain that amalgam is generally safe, biologic dentistry takes a more cautious approach.

Why Mercury Matters

Mercury is a known neurotoxin. Even low-level exposure over time may affect sensitive individuals, potentially contributing to:

• Chronic fatigue

• Headaches or brain fog

• Autoimmune or inflammatory conditions

• Allergic reactions

The risk varies depending on factors such as number of fillings, chewing habits, and individual sensitivity.

Safe Alternatives

Biologic dentistry favors mercury-free materials like:

• Composite resins

• Porcelain or ceramic restorations

• Gold or other biocompatible metals

These materials offer strong durability without the potential risks of mercury exposure.

Safe Mercury Removal

If you have existing amalgam fillings and want them removed, the process matters. Biologic dentists follow strict safety protocols to minimize exposure during removal:

1. Isolation and suction to prevent inhaling mercury vapors

2. Protective barriers for gums and skin

3. HEPA filtration and ventilation to safeguard air quality

This careful approach reduces risk to you, your dental team, and the environment.

Takeaway:
Mercury in dental fillings is still a concern, especially for those with sensitivities or chronic health issues. Choosing mercury-free alternatives and safe removal methods is a core principle of biologic dentistry, protecting your health both now and long-term.
