Dental composite fillings are a mixture of powdered glass and plastic resin. They are sometimes referred to as white, plastic, or tooth-colored fillings. The durability of any dental restoration is influenced not only by the material it is made from but also by the dentist’s technique when placing the restoration. Other factors include the supporting materials used in the procedure and the patient’s cooperation during the procedure. The longevity of a restoration depends upon inherent properties of the materials used, the patient’s overall health, dental hygiene, home care, and diet and chewing habits.
