A composite filling is preferred over the silver amalgam filling because the composite filling is tooth-colored. These fillings are used to repair teeth with cavities or decay. Composite fillings can also be used to correct cracked or fractured teeth. Typically, the affected area of the tooth will be removed and then filled with the composite filling.
Composite and silver amalgam fillings are among the most used materials for fillings. Although these are the most popular, there are other types of filling materials available. All filling material options have advantages and disadvantages that should be discussed with your dental care provider. Composite fillings are most closely matched to the natural color of the tooth and provide the most aesthetically pleasing result. Composite fillings are generally long lasting and very durable. A disadvantage to composite fillings, as with any dental restoration, is that they wear with time and may need replacement in the future.
