Many people have silver/mercury fillings from years past in their mouths. These fillings are not particularly pleasing to the eye, and we know that by unavoidable design, silver/mercury fillings ultimately result in a weaker tooth structure. Porcelain inlays and composite resins create fillings that are not only beautiful (or invisible) but also add strength to weakened teeth. These restorations are esthetically pleasing and very strong thanks to new bonding technologies.
