When can Class V composite resin restorations be polished?

Polishing Class V composite resin restorations can be performed immediately after application due to the fast-setting nature of many modern composite materials. These composites often have a quick curing time, allowing them to achieve sufficient hardness right after curing has completed. This allows for the immediate contouring and polishing of the restoration to achieve optimal aesthetics and surface smoothness. Immediate polishing is beneficial because it helps in eliminating any surface irregularities and can improve plaque resistance by providing a smooth surface.

Other timeframes, such as waiting a specific number of hours or days, are not necessary with the advancements in composite technology, which provide adequate hardness for immediate finishing. The idea that polishing should wait several days or weeks is based on older materials that required longer to reach full set or hardness, which is no longer a concern with modern composite resins.
