Instead of the traditional scrape-and-polish approach, we start with a biofilm-disclosing solution, a stain that reveals exactly where plaque and biofilm are hiding on your teeth. Then we combine air, water, and fine powder particles, often erythritol, gentle on your enamel and easy on sensitive teeth and gums, to remove it along with surface stain. It's more comfortable, more thorough, and better supports the long-term health of your teeth and gums.
