Which material is commonly used for aesthetic filling restorations?

Composite resin is a commonly used material for aesthetic filling restorations due to its excellent cosmetic properties. It can be easily color-matched to the natural shade of a patient’s teeth, providing an aesthetically pleasing result that blends seamlessly with the surrounding dentition. Composite resins consist of a mixture of plastic and fine glass particles, which not only makes them suitable for aesthetic purposes but also allows for effective bonding to tooth structure, contributing to the restoration's strength.

Additionally, composite materials are versatile and can be used in various applications, including anterior and posterior restorations. Their ability to be sculpted and polished to a natural finish further enhances their appearance. This makes them a popular choice among dentists who focus on providing a natural, aesthetically pleasing outcome for their patients.

Other materials mentioned, like amalgam and gold, while durable, do not possess the same aesthetic qualities as composite resin. Amalgam is primarily used for posterior teeth where aesthetics are less of a concern, and gold, though strong and long-lasting, is also not aesthetically pleasing for visible areas. Porcelain can be used for aesthetic restorations and is often used in crowns or veneers, but composite resin is typically the first choice for filling cavities.
