Features 10% hydrogen peroxide, wireless tooth-whitening technology to provide fast, effective, and pain-free at-home treatments to patients. Patients get up to 6 shades whiter with zero sensitivity. Easy, brush on, professional-strength whitening gel safely whitens teeth without sensitivity, while the vitamin E and aloe lip care nourishes and hydrates lips. Brush a thin layer of gel onto the tooth surface: it will stay put as it penetrates and evaporates. It is safe to swallow while the gel is on teeth. Wait 3–5 minutes between applications. For best results, complete 3 consecutive applications per day and use as needed for touch-ups.
