Why are tooth-colored fillings preferred over the old amalgam (silver) fillings?

There are many reasons why Dr. Johnson prefers to use tooth-colored fillings in his Park City, Utah cosmetic dental practice. Silver (mercury) fillings have been used for decades; however, recent and ongoing research shows that due to the expansive nature of this material, fractures and cracking of teeth often occurs. Teeth restored with old silver fillings do not reflect light, and, therefore, give the appearance of darkened, gray teeth. Additionally, the mercury in these fillings has been shown to have systemic effects on the immune system. We do not feel silver fillings are the safest and best choice anymore, and that is why we only use tooth-colored (white) fillings on our cosmetic dentistry patients.
