Geneva, November 7, 2025 – The Sixth Conference of the Parties (COP-6) to the Minamata Convention on Mercury has adopted a landmark amendment, setting a 2034 deadline for the global elimination of dental amalgam-a mercury-containing material long used in dental restorations and denture-related repairs. This science-backed decision marks a decisive shift toward mercury-free dentistry, addressing severe health and environmental risks posed by the material.
Key regional actions are already underway. China has banned dental amalgam use for minors under 15, pregnant, and lactating women, with strict enforcement of bulk mercury prohibitions in dental practices. The EU will halt exports of dental amalgam in 2025 and cease all production by 2026, accelerating its transition to alternative materials. Dental amalgam, which contains over 50% mercury, releases toxic vapor during chewing and cremation, contaminating air, water, and soil globally.
For the denture and dental restoration sector, the amendment drives urgent adoption of mercury-free alternatives. Resin composites and glass ionomers-proven cost-effective and durable-are leading replacements, offering benefits like tooth structure preservation and fluoride release to prevent cavities. Industry leaders note the shift aligns with rising demand for biocompatible, aesthetic denture solutions, while eliminating long-term environmental costs linked to mercury waste.
As over 150 parties implement national action plans, the denture industry enters a sustainable era. The transition not only safeguards public health and ecosystems but also accelerates innovation in digital and biomimetic dental materials, paving the way for safer, more effective tooth replacement solutions worldwide.
