A composite filling is a tooth-colored resin and glass mixture. This is a versatile material that can be used to repair teeth after decay is removed or to cosmetically enhance teeth by changing their shape and/or color.
How is a composite filling placed?
Composite fillings are placed much like a traditional filling. The tooth is first numbed to ensure complete comfort throughout the procedure. The composite is then applied in layers, using a light designed to harden the material after each application. After the layers of composite have been applied, the composite is then shaped to fit the tooth and polished to prevent staining and early wear.
What are the advantages of composite fillings?
Traditional fillings are done using metals like silver or gold which are easily visible in the mouth. Composite fillings are more discrete since they more closely match the color of the tooth. This is especially important when front teeth are being restored. Unlike metal fillings, the composite material actually chemically bonds to the tooth structure, which provides further support to the tooth. And composites have increased versatility as they can be used not only as a filling for decay but also to repair chipped, broken, or worn teeth.
