Why Mercury Dental Fillings Are Being Phased Out Worldwide

What the Global Amalgam Ban Means for Your Smile

Dentistry is evolving—particularly when it comes to restorative materials.

The United Nations’ Minamata Convention has adopted a global phase-out of mercury-added dental amalgam, set to take full effect by January 1, 2035. While many countries have begun reducing amalgam use in recent years, this agreement marks a significant international shift.

The global agreement stops the manufacture and sale of mercury-containing dental amalgam. This is part of a larger effort to reduce exposure to mercury, a heavy metal that’s been used in dental amalgam for over 150 years.

At Nashville Restorative Dentistry, mercury-free and mercury-safe dentistry has long been part of our standard of care. This global decision simply reinforces an approach we’ve followed for years.

What the Amalgam Phase-Out Means for Patients

1. A renewed focus on health and safety

The global ban is aimed at protecting human and environmental health from the harmful effects of mercury. Dental amalgam contains mercury, a known neurotoxin. As amalgam fillings age, chewing and grinding release mercury vapor, which can accumulate in the body over time. Mercury is a highly toxic substance whose even small exposure can cause significant health challenges.

Many patients prefer restorative materials that align with a preventive, biologically respectful approach to health.

2. Environmental responsibility matters

Mercury does not disappear after dental use—it can contaminate water systems, soil, and wildlife. Reducing mercury use in dentistry benefits both public health and the environment. Reducing mercury use in dentistry helps protect both ecosystems and public health worldwide. Additionally, the global ban alleviates the cost challenges associated with the disposal of dental amalgam.

Composite materials eliminate these concerns while offering excellent strength and aesthetics, making them a smart choice for patients and the planet alike.

3. Composite fillings are now the standard

As amalgam use declines, materials such as composite resin, glass ionomer, and gold continue to be superior alternatives. Composite fillings are widely used because they:

• Blend naturally with tooth structure
• Require less removal of healthy enamel
• Bond directly to the tooth for added durability

This has been our preferred approach for years. Our team is experienced in placing high-quality composite fillings that look great and support long-term oral health. 

4. Safe removal requires specialized training

If you have existing amalgam fillings that are failing—or if you’re considering removal for health reasons—it’s essential that the process is done safely.

Not all dentists are trained in the safe removal of mercury. Our practice follows the IAOMT’s SMART (Safe Mercury Amalgam Removal Technique) protocols designed to protect patients, staff, and the environment. 

Over 50 countries, including 27 states of the European Union, have already phased out dental amalgam. Unfortunately, some countries, including the United States, haven’t stopped their use. Forward-thinking practices like Nashville Restorative Dentistry are ahead of the curve. We embrace the global phase-out of dental amalgam because it’s a natural extension of our existing standards of care.
