Countries around the world have agreed under the Minamata Convention on Mercury to completely stop using mercury-based dental amalgam by the year 2034.
This important decision was made at a conference held in Geneva to protect human health and the environment from mercury pollution.
The Minamata Convention on Mercury was adopted in 2013 and came into force in 2017.
More than 150 countries are members of this convention.
The World Health Organization (WHO) lists mercury among the top ten chemicals that pose serious risks to human health.
The agreement also aims to end the use of mercury in skin-lightening cosmetics and small-scale gold mining.
