In restorative dentistry, what material is commonly used for dental fillings?

Composite resin is commonly chosen for dental fillings due to its aesthetic appeal and versatility. This material can be closely matched to the natural color of teeth, making it an ideal option for visible areas in the mouth. Its ability to bond directly to the tooth structure enhances its durability and contributes to a more effective seal, reducing the likelihood of recurrence of decay.

In addition to its aesthetic advantages, composite resin offers flexibility in its application. It can be layered to achieve different shades and translucencies, providing a natural appearance that most patients desire. Furthermore, composite materials have improved significantly over the years in terms of their wear resistance and strength, suitable for both anterior and posterior teeth.

Consideration of other filling materials reveals their specific uses and properties. Gold, while highly durable and biocompatible, is more costly and less aesthetic for many patients. Amalgam is known for its strength and longevity, making it suitable for posterior teeth but lacking the cosmetic appeal of composite. Glass ionomer, while beneficial for its release of fluoride and bond to tooth structure, generally offers lower strength compared to composite. Each material has its unique advantages, but composite resin stands out for its combination of aesthetic and functional properties, making it a preferred choice in restorative dentistry.
