Today’s alternative to unsightly and controversial mercury-silver amalgams are white, or resin, fillings. Silver, or amalgam fillings contain about 50% mercury, a chemical that has been scientifically shown with very high toxicity levels. This has led to a movement towards mercury-free dentistry.
In addition to being safer, white fillings are much more aesthetically pleasing. With white fillings, no one even needs to know that you have been to the dentist. By matching the white filling to your own tooth color, white resin fillings become virtually invisible and look just like natural teeth.
