Dental fillings are used to repair teeth affected by cavities, cracks, or minor damage. At Austin Longevity , we use modern, tooth-colored composite materials that bond directly to the tooth structure and restore both function and appearance. Fillings stop decay from progressing, prevent further damage, and protect the inside of the tooth from infection. Modern composite fillings have largely replaced traditional silver amalgam fillings for most cases. Composite fillings are made of a tooth-colored resin that's matched to your natural tooth shade, making them virtually invisible. They also bond directly to the tooth, which means less of your natural tooth structure needs to be removed compared to amalgam fillings. The result is a stronger, more aesthetic restoration that preserves more of your tooth. The filling procedure is straightforward and typically completed in one visit lasting 30 to 60 minutes per tooth. After numbing the area with local anesthesia, the dentist removes any decayed or damaged tooth material, cleans the area, and applies the composite resin in layers, hardening each layer with a special light. The filling is then shaped and polished to match the natural contours of your tooth and feel comfortable in your bite. Most patients return to normal eating shortly after the appointment, once the numbness from the anesthesia has worn off.
