What is dental amalgam?
Dental amalgam is a tooth filling material that is approximately 50% mercury. It is sometimes misleadingly called a “silver filling”, even though it contains far more mercury than silver. Mercury, a heavy metal, is known to be poisonous to the human nervous system.
There are still dentists out there who use this toxic mercury product, so make sure to say “No amalgam!” before you ever sit in that dental chair. Ask for mercury-free fillings instead!
