What polishing agent is preferred for healthy enamel?

The preferred polishing agent for healthy enamel is fine grit for final polish. This choice is based on the need to maintain the integrity of the enamel while providing a smooth surface after polishing. Fine grit polishing agents are designed to be less abrasive, which minimizes the risk of damaging the enamel or creating micro-abrasions that can lead to wear over time.

Using fine grit allows for the effective removal of plaque and surface stains while ensuring that the enamel's hardness and overall health are preserved. This method promotes an aesthetically pleasing result without compromising the strength of the teeth. In contrast, coarser grits may leave the enamel more susceptible to damage or erosion, and using a medium grit could result in a less refined finish that doesn't achieve the desired smoothness. Thus, the final polish with a fine grit is the most suitable approach for maintaining the health and appearance of enamel.
