The American Dental Association reports that there has been no scientific evidence to show that amalgams (silver fillings) containing mercury are harmful to humans. But, in keeping with up-to-date technology in tooth restoration, Dr. Schleiffarth uses natural-colored fillings instead of metal and mercury. These new white fillings are dramatically more attractive and aesthetically pleasing. Many of Dr. Schleiffarth’s patients have him replace their old silver amalgams with new white fillings.
