As well as providing an effective repair for tooth decay or damage, composite (or white) fillings are also a natural-looking alternative to more obvious amalgam fillings. This is because they are made from tooth-coloured resin; a mixture of plastic and glass that blends in beautifully with your teeth.
They support the structure of a damaged tooth, helping to prevent further breakage or sensitivity, and can be placed in the front or back teeth.
Although not considered to be as long-lasting as amalgam fillings, composite fillings are a far more attractive option and are now produced from modern materials that offer improved durability, particularly in small cavities. How long they last will depend on the depth of the cavity to be filled and its position in the mouth.
To prevent decay forming around the composite filling, it is important to brush at least twice a day and see your dentist for regular check-ups.
