White Fillings River Crossing Dental only uses Tooth Colored Fillings. This provides you with a better smile & eliminates the look of silver fillings in your mouth. Tooth-colored fillings are a safer and more attractive alternative to older silver amalgam fillings. By precisely matching tooth-colored composite fillings with the natural color of your teeth, we are able to provide you with white fillings that are virtually invisible. The removal of amalgam fillings can provide patients with white fillings that provide a more pleasing, silver-free smile. Silver amalgam fillings contain about 50 percent mercury, a chemical that has been scientifically shown to be more toxic than lead, cadmium, or arsenic. The possibility of mercury leaking from amalgam fillings over time has prompted a movement toward mercury-free dentistry.
