Its members have chronicled and promoted the research that has proven beyond a reasonable doubt that dental amalgam is a source of significant mercury exposure, and a hazard to health. It has taken the lead in educating dentists and allied professionals in the methods of safely dealing with amalgam fillings, and safely disposing the waste. It has also led the way in developing more biocompatible approaches in other areas of dentistry, including endodontics, periodontics, and disease prevention. All this while maintaining the motto, “Show me the science!” 


And to always seek the safest, least toxic way to accomplish the mission of treatment, to do it while treading as softly as possible on the patient’s biological terrain.

International Advocate


After years of experience in finance and real estate ventures, Anita Vazquez Tibau turned her understanding of law and passion for equity into a career as a spokesperson, panelist, advisor, policy activist, and health/wellness conference coordinator with the goal of ending dental mercury. This began 15 years ago when she served as a representative for Consumers for Dental Choice, and her work as a renowned international dental consumer advocate has been growing ever since.


Ms. Tibau launched Californians for Green Dentistry in 2010 and serves as the group’s Executive Director. This position has led her to cooperate with a small group of professionals in securing city resolutions from Costa Mesa, Santa Ana, and Malibu, all with the message of banning mercury in dentistry. She also garnered a resolution to end dental mercury from the prestigious Californian State branch of the League of United Latin American Citizens (LULAC).

For the past several years, Ms. Tibau has served as a representative of the International Academy of Oral Medicine and Toxicology (IAOMT) at a wide variety of government meetings about dental amalgam mercury. Her deep understanding of the issue and her fluency in English, Spanish, and Portuguese have assisted Ms. Tibau in successfully making an impact at all of the intercessional negotiating committees of the United Nations Environment Programme (UNEP) which led to the Minamata Convention on Mercury. She also presented to the Group of Latin American and Caribbean Countries (GRULAC) at a regional session in Bogota, Colombia.

When she delivered the closing remarks to the UNEP delegation on behalf of the IAOMT at the final session of the Minamata Convention on Mercury, Ms. Tibau was proud to share the announcement of IAOMT’s Technical Assistance Programme (TAP) with the world.

She recently has published in the International Dental Tribune entitled “The future of dentistry in a world without mercury: An NGO's perspective” about her work on the Minamata Convention on Mercury, as well as a continuing update on Brasil’s move away from mercury in the dental sector.
