We've got something for you to smile about! Formulated with Calprox -- a proprietary, low-abrasive teeth whitening ingredient -- the Supersmile teeth whitening system includes toothpaste and accelerator that when used together, work to gently remove stains chemically rather than abrasively (and with no messy strips or trays!). Plus, we've included a shade guide so you can track your progress. This super-size system provides a year's supply of toothpaste and accelerator for one person (or share this fabulous find with a family member or friend and you'll both enjoy a six-month supply). In a clinical study, after 30 days of using the Supersmile professional whitening system, the average shade difference was 3.24 shades, with a maximum benefit of 6.33 shades. How do I use it: Use a pearl-sized drop of both the toothpaste and accelerator together on a dry toothbrush (yes, dry!). Brush the area between each tooth where the gumline meets and make tiny circles for two minutes, twice daily. From Supersmile. Includes:
