What are they?
A filling replaces part of a tooth that has been lost because of decay or through accidental damage. This can be in the form of silver amalgam filling or composite white filling.
Dental amalgam is a mixture of mercury, silver, tin and copper.
Mercury as part of a compound in dental amalgam is not poisonous.
This has been proven by 100 years of ongoing scientific research.
Dental amalgam fillings are known to be strong and durable and last many years.
