Dental Materials include a variety of options for fillings and restorations. Common tooth colored options include a plastic like material called composite, porcelains, porcelain fused to gold, and preventative sealants. Other common fillings are made out of silver and gold alloys. Each type of material has unique properties and indications. Some types of material will tend to corrode after time, while other materials, like gold, resist corrosion. Material selection can be very confusing, and you may have a strong preference for one material over another. It is important to communicate thoroughly with your dental team to discuss all material choices and to ask questions.
