Tooth-Colored Fillings in Fremont

Dental fillings have been around for thousands of years. Archaeologists have found evidence of molars filled with beeswax that date back some 6,500 years ago. Beginning in the 19th century, a cavity was filled with metal; gold, tin or silver was softened and set in the tooth. Later in that same century, amalgam fillings made up of tin, silver, mercury, and copper were introduced. It didn’t take long for controversy to arise over the use of mercury in metal fillings. Today, however, there are tooth-colored fillings made of composite resin materials that are not only safer than amalgam fillings, they are also a better aesthetic option.

Safely Removing Metal Fillings

If you have amalgam fillings that you would like to replace whether for aesthetic or health reasons, Dr. Block can safely remove them. A metal filling needs to be drilled out, so to minimize the release of mercury during this procedure, we’ll cool the filling with water and air during drilling. Dr. Block may elect to cut the filling into separate chunks, which reduces the drilling required and allows him to remove the chunks with a hand instrument or by suction.

Placing a Tooth-Colored Filling

Once the metal filling is removed—or when you need to repair a newly discovered cavity with a filling—Dr. Block will prepare your tooth for a tooth-colored filling, also called a composite filling. In this case, your tooth will require less preparation than with a metal filling. For you, this means less time having to endure the drill, and for Dr. Block it means being able to preserve more of your tooth’s natural structure.

The Advantages of a Composite Filling

Unlike a metal filling that is wedged between the cusps of your tooth and held in place by pressure, a composite filling bonds to your remaining tooth structure. With a composite filling, Dr. Block only needs to remove that part of your tooth that has been damaged by decay; no additional tooth structure needs to be removed in order to hold the filling in place. And a tooth with more natural tooth structure is always stronger and more likely to have greater longevity.

In addition, because of the bond between a tooth-colored filling and your tooth, there is less likely to be tooth cracks or fractures, as well as seepage, which can happen with amalgam fillings.
