Dental fillings are used to seal the structure of a damaged tooth. Dentists will use a dental restorative material to secure and restore the functionality and structure of the damaged tooth. Damage to teeth can occur for a variety of reasons including sporting injuries or physical damage, poor oral hygiene, and tooth decay.
In the past, it has been common to use a variety of metal alloys as a filling material which can sometimes include cobalt, chrome, nickel, silver amalgam, mercury, tin, and sometimes copper. This is now a very outdated practice due to the toxicity of some of these substances.
Alternative techniques include glass and ceramic fillings which are fabricated to match the colour of surrounding teeth. Sydney Smiles Dental uses high-quality restorative material for oral dentistry known as composite resin that is safe for oral treatment and is also easily colour matched with surrounding teeth.
