Our office does not offer mercury silver dental fillings. Dr. McElhaney believes that tooth colored, composite fillings are a stronger and healthier choice for our patients. The tooth colored material is metal free and made from plastic resin. They are very durable, tissue compatible, kind to the opposing teeth, and stain resistant. Tooth colored dental fillings allow us to preserve the greatest amount of natural tooth enamel, and perhaps more importantly, they are made from inert non-toxic ingredients.
