Restorative materials are substances used in dentistry to repair or restore the function and appearance of damaged teeth. Common types include composite resins, amalgam, and glass ionomer cements. These materials help to fill cavities, fix fractures, and improve the overall aesthetics of a patient's smile. These materials are designed to bond with the tooth structure, providing strength and durability. They can also be used in various dental procedures, such as crowns, bridges, and veneers. The choice of restorative material often depends on factors like the location of the tooth, the extent of damage, and patient preferences.
