Why are “white” fillings better than silver?
In a 1993 U. S. Public Health Service report it was stated that there is no health reason not to use amalgam (silver). Most patients request that the white material be used so it will look more natural. The white material “bond” better to tooth structure and can internally strengthen the tooth. Once the area to be restored is sufficiently large, or fracturing is occurring, neither the “white” or “silver” materials is strong enough to restore the tooth for optimal function. At a certain point of weakness, a crown or onlay will usually be necessary and will provide better overall satisfaction for the patient.
