Why We Prefer Composite Fillings

If you have the old-fashioned, silver amalgam fillings, you already know about one of their weaknesses: they stand out. You can see them in any picture that features an open-mouth smile, laughter, or even lively conversation. Thing of it is, amalgam fillings have other drawbacks that you may not be aware of. At the St. Petersburg Dental Center, we prefer composite fillings, and here’s why:

The Problems With Amalgam

Amalgam fillings are made from a mixture of zinc, copper, silver, tin, and mercury. Aside from the obvious aesthetic concerns of silver amalgam fillings, they also pose the following problems:

  • They require extensive preparation, which means we have to remove more of the tooth’s surface
  • They don’t bond directly with your tooth
  • Some people experience allergic reactions to the mercury in each filling
  • While it has not been proven, the mercury used in amalgam fillings could be toxic

The Perks of Composites

Composite fillings, on the other hand, are made from plastic and finely ground glass particles. Composites can be made to closely match the color of your teeth, so no one will know you have fillings! Other perks include:

  • They bond directly to your tooth, which means less of the tooth’s surface needs to be removed
  • Because they bond directly to your tooth, your tooth is actually strengthened by the composite filling
  • They are heat-cured, which makes them stronger than amalgam fillings
  • There are currently no concerns about the safety of the materials used

Not only is it our job to keep your teeth healthy; we want to keep you happy with your smile, as well. Composite fillings are just one way we do both.
