Which technique is recommended for polishing teeth with existing restorations?

Using an ultra-fine abrasive is the most recommended technique for polishing teeth with existing restorations because it effectively smooths and polishes the surface without causing damage to the restoration material. Restorations such as fillings and crowns can be sensitive to aggressive polishing techniques or coarse abrasives, which may create scratches or even compromise the integrity of the restoration.

Ultra-fine abrasives are specifically designed to provide a gentle polishing effect, allowing for a nice shine while being less abrasive to the surfaces of both natural teeth and restorative materials. This approach reduces the risk of scratching, preserves the longevity of the restorations, and contributes to the overall aesthetics and health of the dental work.

Other techniques, such as using a high-speed drill, could potentially damage restorations and natural enamel due to the increased friction and heat produced. Heavy polishing pastes may also be too abrasive for delicate surfaces, leading to scratches or weakening of the restoration. Choosing not to polish at all might not provide the aesthetic enhancement desired and could leave surfaces less smooth, potentially leading to plaque accumulation. Therefore, utilizing an ultra-fine abrasive stands out as the most appropriate and effective choice in this context.
