One of the most commonly treated problems when it comes to teeth is the dental cavity. This is a hole in your tooth that occurs due to decay. Decay can be prevented, but when teeth are not properly taken care of, these cavities and other dental problems can emerge.
Cavities are usually treated with a filling. One of the oldest types of fillings that dentists use to fill these holes with is the amalgam filling. This is a substance that consists of around 40% mercury and another type of metal. The reason why this filling became so popular is because of the fact that this filling is tough, apart from the fact that it is rather cheap and the treatment of the cavity can be done in a single visit.
