DaVinci Laser Teeth Whitening Gel is strong enough to deliver the results clients want, yet gentle enough to provide a noninvasive, pleasurable teeth whitening experience. They manufacture their teeth whitening gels using only the highest quality USA organic, plant and mineral-based ingredients. The active ingredient in their gel is a food-grade hydrogen peroxide and contains 3 key minerals to stabilize and strengthen the enamel. These products are proven to whiten as well — or better — than other dental whiteners, but without the level of sensitivity and side effects that other whiteners can deliver.
