Always use light pressure and low speeds. Pre-polish with a fine grit rubber wheel. Use tripoli compound on a soft or medium felt wheel or a soft bristle brush. Polish with rouge on a rag wheel, soft bristle brush, or chamois. Ultrasonically clean in water or denatured alcohol for five minutes. Final polish with a tin oxide/alcohol slurry or dry tin oxide on a soft bristle brush. Buff with a clean rag wheel. Notes High shine, rouge-impregnated wheels and/or points can take the place of Steps 2 and 3. Fine sandpaper and cuttle disks can replace Step 1. Occlusal pits and fissures can be smoothed and burnished with a dull #1/2 round bur.
