A white filling is, technically, a composite resin which is bonded to the tooth. These “fillings” have been greatly improved over the years and are now the most widely used restorative material in America—mainly because they are white. They are an obvious aesthetic improvement over silver amalgam fillings and, in some situations, can last as long as amalgams. A white filling is used to repair a tooth that is affected by decay, cracks, fractures, and other minor dental flaws. Dr. Regan can closely match composite or cosmetic (white) fillings to the color of your existing teeth for an aesthetically pleasing smile and a filling that is not noticeable or obvious.
