White/ composite fillings are a great aesthetic option as they are tooth-coloured fillings placed after decayed or unhealthy tooth structure is removed. The dentist can blend the shades to create a colour that matches the actual tooth, which creates an illusion of there being no filling at all. Composites bond to the tooth and support the remaining tooth structure. It helps prevent breakage and insulates the tooth from changes in temperature.
Amalgam fillings are silver fillings that are occasionally recommended for back teeth (such as molars) where white fillings may be difficult to place.
