A dental filling restores a tooth damaged by cavities back to its standard shape and function and prevents decay from progressing further. A cavity forms when bacteria erode the enamel, and the decay penetrates the dentin, the tooth's inner layer. When this happens, the pulp layer can also become exposed and eventually infected.
Cavities must be treated with durable restorations to prevent further damage and allow patients to chew and speak properly. Dental fillings can help restore both the function and the cosmetic appearance of a tooth damaged by tooth decay or trauma.
