Xwhite teeth whitening strips have undergone rigorous laboratory tests and shown to be safe for tooth enamel. Indeed, the strips were shown to have a similar effect on the surface microhardness of tooth enamel as treating with water. Additionally, Xwhite teeth whitening strips do not cause tooth or gum sensitivity. Xwhite strips are a CLEAN product, free of harmful and toxic ingredients.

Xwhite® New Patented P³ Technology is the combination of either hydrogen peroxide or the non-peroxide ingredient PAP (Phthalimidoperoxycaproic Acid) with two additional components called polyphosphates, which work synergistically to significantly improve the whitening efficacy of the formulation.

One of the key benefits of P3 Technology is that it can enable superior whitening without the highest levels of hydrogen peroxide, which can cause some tooth sensitivity, particular when used for prolonged periods and at high strength, such as with in-dental practice procedures.

Incorporation of the P3 Technology into a non-peroxide PAP strip allows the strip to have equivalent whitening to a 6% hydrogen peroxide strip. The combination of PAP with [P]3 is twice as effective at whitening as PAP on its own.

Incorporation of the P3 Technology into a 6% hydrogen peroxide dissolving strip can allow the product to have equivalent whitening to a 10% hydrogen peroxide strip when used twice per day.
