A filling restores the lost tooth structure. One of the leading causes of tooth structure loss occurs when you have caries (tooth decay), but it can also be caused by trauma, tooth erosion, and developmental defects. There are three main types of filling materials routinely used in dentistry. Composite resin and glass ionomers are tooth-colored filling materials, and amalgam is silver-colored. Composite resin is the most commonly used filling material. Amalgam fillings are usually recommended when composite resins cannot be used.
