Using a combination of whitening gel and FDA-approved blue accelerating lights, the DaVinci teeth-whitening system can leave teeth an average of up to eight shades whiter. During office visits, clients apply the signature whitening solution?an organic plant- and mineral-based gel?to chompers. A specially designed LED laser light is used with the food-grade hydrogen peroxide gel to lift lingering stains. Once the tonal transformation is complete, patients may walk away with the graffiti of tobacco, wine, coffee, and age erased from their smiles. To continue the process, Davinci also produces a take-home personal whitening kit that includes 12 gel applications, an LED accelerator light, custom-fitted trays, and remineralizing and desensitizing gel to care for enamel.
