Composite fillings are also called tooth colored fillings and fill dental cavities. Composite fillings can provide very close resemblence to the natural teeth, thereby providing an indistinguishable restoration alternative to the silver/gray colored fillings. This is especially important for restorations in the front tooth.
As the name indicates, Composite fillings are created from a complex compund and can be made to resemble the appearance of the natural tooth. They are strong, durable and cosmetically superior to silver or dark grey colored amalgam fillings. However, composite resin fillings are usually more expensive than silver amalgam fillings.
Besides the aesthetic advantage of composite fillings over amalgam fillings, the preparation of composite fillings requires less removal of tooth structure to achieve adequate strength. This is because composite resins bind to enamel (and dentin too, although not as well) via a micromechanical bond. As conservation of tooth structure is a key ingredient in tooth preservation, many dentists prefer placing composite instead of amalgam fillings whenever possible.
Durability of Composite Fillings
Composite fillings are very durable, and will last many years. However, the longevity will depend on the level of dental hygeine maintained by the patient. Good oral hygiene practices, eating habits, and regular dental visits will aid in the life of the fillings.
