With recent advances in dental material technology and bonding techniques, dentists have alternatives to placing silver amalgam fillings.

The decay or old filling is removed and the tooth is prepared to accept the restoration. Generally, a smaller amount of tooth structure is removed when preparing for a tooth colored filling. The tooth is then "etched" with a mild acidic solution. This roughens the enamel surface and allows the bonding material to adhere. A shade of composite material is chosen that matches your natural tooth and is placed into the tooth. The dentist then shines a bright light on the area to harden the material. The filling is then trimmed to adjust to your bite and to achieve proper contour and shape.

How Long Will Tooth Colored Fillings Last?

How long any filling lasts depends on many factors. First, smaller fillings that are surrounded by natural tooth structure will last much longer than large fillings that are not surrounded by natural tooth structure. Secondly, how much biting pressure is exerted by opposing teeth is also important. Home care, frequency of check up visits and quality of diet are also factors that affect the longevity of fillings. Tooth colored fillings can last years before needing repair or replacement.
