Fillings generally fall into two types, metallic or white. Metallic fillings can be longer lasting whilst white materials are more aesthetic. Your dentist will explain the differences whenever this type of restoration is recommended.
White (composite) fillings can offer a natural looking way to support the remaining structure of a damaged tooth and prevent further breakage or discomfort. They can also be used to replace unsightly amalgam fillings.
Their chief advantage is the way they blend so well with your natural teeth. They are made of durable materials and can offer a long lasting solution in an appropriately chosen case. Composite fillings can be more difficult to place than their metallic alternatives so your dentist longer may require a longer appointment time.
Dental amalgam is the traditional silver-coloured filling we are all familiar with. Whilst composite (tooth coloured) fillings are becoming more popular, amalgam fillings can offer a durable and long-lasting solution, especially under adverse circumstances. Fillings can also be made out of gold, but this practice has been largely superseded by white ceramic alternatives.
