What happens to the sealant material over time if filled resin is used?

When filled resin is used as a sealant material, over time, it will naturally experience wear due to the forces of chewing and grinding. This is attributed to the abrasive nature of food and the constant mechanical stress the sealant faces during typical oral functions. As the filled resin sealant wears down, it may lose its effectiveness in protecting the enamel from caries and can lead to the need for reapplication or maintenance.

While other potential outcomes such as becoming porous or hardening completely may occur, the primary concern with filled resin sealants is related to their wear over time. The possibility of requiring less adjustment is not typically characteristic of filled resins, as they may still need occasional check-ups and adjustments as they wear down. This understanding highlights the importance of monitoring sealant integrity during routine dental visits to ensure continued protection for the teeth.
