There are several different materials that can be used and this will depend on the severity of decay in the tooth, the amount of healthy tooth structure remaining and the location of the tooth in your mouth.
- Amalgam – the silver mercury fillings that were placed in teeth by dentists prior to the development of more advanced technologies. Dental amalgam is a mixture of metals, consisting of liquid mercury and a powdered alloy composed of silver, tin, and copper. We do not use amalgam at WA Dental.
- Composite – most commonly used for fillings, the composite resin is a white filling material that matches the shade of your tooth. The composite resin is applied directly to the prepared tooth and sculpted into the right shape. The material hardens and bonds to the tooth structure when it is activated with a blue light. The resin can be polished to a high shine, and fillings can be difficult to distinguish from natural teeth.
- Gold – inlays, onlays and crowns made from gold are the most expensive type of filling. Gold is a long-lasting and durable option, however, due to their appearance and cost, gold fillings are rarely used these days.
- Ceramic – veneers, crowns and bridges made from porcelain/ceramic are very strong and are therefore recommended for larger fillings and teeth with cracks. These restorations provide an excellent cosmetic result because the porcelain can be matched to the colour of the natural tooth.
