Because we believe the type of fillings known as dental amalgams are not in the best interest of our patients, we no longer use silver or mercury filling materials in our practice. We made the decision over 18 years ago to only use bonded composite restorations for fillings we place for our patients. There are several advantages for using this type of restoration over the 50% mercury fillings of the past. The composite materials we use now provide a better seal by bonding with the tooth and actually strengthening the tooth. For patients with metal sensitivities or allergies using composites can greatly help in eliminating their concerns.
