What about "silver" fillings versus "white" fillings?
Although the U.S. Public Health Service issued a report in 1993 stating there is no health reason not to use amalgam (silver fillings), more patients today are requesting "white" or tooth-colored composite fillings. We also prefer tooth-colored fillings because they "bond" to the tooth structure and therefore help strengthen a tooth weakened by decay. White fillings are also usually less sensitive to temperature, and they also look better. However, "white" fillings cannot be used in every situation, and if a tooth is very badly broken-down, a crown will usually be necessary and provide better overall satisfaction for the patient.
