Amalgam Vs Resin Restorations
Most people recognize dental amalgams as silver fillings. Dental amalgam is a mixture of mercury, silver, tin and copper. Mercury, which makes up about 50 percent of the compound, is necessary to bind the metals together to provide a strong, hard, durable filling. After years of research, mercury continues to be the only element that will bind these metals together in such a way that it can be easily manipulated to fill a cavity.
Resin composite fillings are made of ceramic and plastic compounds. Because resins mimic the appearance of natural teeth, these fillings have been used in front teeth for years. When they first appeared, however, resin compounds weren't strong enough to be used in back teeth, where high-pressure grinding and chewing require greater durability. In the past 10 years, technology has improved enough to allow the use of resin material in posterior or back teeth. Still, many dental plans don't cover resin fillings in teeth that aren't visible in a smile, and many dentists choose not to use resins for one or more resons such as what they learned in dental school, and the fact that silver fillings are cheaper and therefore mostly covered by dental coverage.
Amalgam restorations have served the profession well and will continue to do so in the years to come. However, Composite resins offer a better seal and meet the patient's demands for esthetics. Fears about their longevity are unfounded and they perform well in clinical conditions.
