This can lead to <strong>staining, bacterial colonization, and premature wear<\/strong> of the restoration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For optimal polishing, use <strong>fine-grit diamond burs, silicone polishers, felt wheels with diamond paste, and low-abrasion polishing pastes<\/strong> designed for specific restorative materials.
