Silver Fillings – also known as Amalgam Fillings – have been in use in the dental industry for many years. Manufactured from a metal alloy that includes Mercury, it was the most effective type of restoration for fillings. The metal contracts or expands according to the temperature of whatever substances are placed within the mouth. This reaction prevents bacteria from entering a tooth after it’s been filled and promotes oral hygiene.
White Fillings, which are referred to as composites or resins, are typically made from glass or plastic polymers. This type of filling permits your dentist to fill in cavities with a substance that feels and looks very similar to your own natural tooth structure. This restoration is made with a resin material that fits into a tooth and prevents decay. Instead of a silver or gray material inside your mouth, the composite color is matched with the color of your teeth.
