Here’s a comprehensive overview of white composite fillings:
White composite fillings are made from a mixture of fine glass particles and a plastic resin. They are used to repair decayed, damaged, or discoloured teeth. Unlike traditional amalgam (silver) fillings, composite fillings are tooth-coloured, making them blend seamlessly with the natural tooth structure.
1. Preparation
The dentist will numb the area around the tooth to ensure comfort during the procedure. The decayed or damaged portion of the tooth is removed, and the tooth is cleaned.
2. Etching
A weak acid is applied to the tooth to roughen the surface slightly. This helps the bonding agent adhere better to the tooth.
3. Bonding Agent
A liquid bonding agent is applied to the etched surface, which helps the composite material stick to the tooth.
4. Layering the Composite Resin
The composite resin is applied in layers. Each layer is shaped and then hardened using a special curing light. This process is repeated until the cavity is filled and the tooth is restored to its natural shape.
5. Shaping and Polishing
Once the filling is hardened, the dentist will trim, shape, and polish it to ensure it matches the natural contours and sheen of the tooth.
White composite fillings offer a reliable, aesthetically pleasing option for restoring damaged or decayed teeth. They provide good durability, especially when proper dental hygiene practices are maintained. Consulting with your dentist can help determine if composite fillings are the best choice for your dental needs.
