Fillings are required when the tooth has a “cavity” or has a defect. The decay is removed and then a filling material – either tooth colored or silver – is placed. An old filling may also need to replaced due to wear, stain or new decay around the edges of the filling.
Composite resins, or tooth-colored fillings, provide good durability and resistance and are best used in small to medium-sized restorations. They can be used on either front or back teeth. Composites cost more than amalgam or silver fillings and occasionally are not covered by some insurance plans. Silver fillings can last 40 or more years, tooth-colored fillings should last 10-15 years.
Tooth-colored fillings are now used more often than amalgam or silver fillings. However, in some cases an amalgam or silver filling may be the best choice.
Replacing Silver Fillings with a Tooth Colored Restoration
You can have your silver fillings replaced with tooth-colored restorations. The Doctor will discuss what options are available for you. Small to medium sized fillings can be replaced in one appointment. Larger fillings may require a crown to strengthen the tooth.
