Crest 3D Whitestrips Professional White Kit

Crest 3D Whitestrips Professional White Kit is the complete course rather than a trial pack — enough treatments to take teeth through a full whitening cycle and see the finished result.

The strips use hydrogen peroxide, the same active dentists use professionally, at a concentration set for safe daily home use. Unlike a whitening toothpaste, which only polishes the surface, peroxide breaks down the pigment inside the enamel — which is why it removes stains that brushing never touches.

How to use: apply the upper and lower strips along the gum line, leave for the time stated on the pack, then peel off. Complete the full course without skipping days for an even result.

Frequently asked questions

How long before I see a difference?
Most people notice a change within the first few treatments, with the full result at the end of the course. The shade then holds for months with normal care.

Can I drink coffee during the course?
You can, but the teeth are more porous straight after a treatment. Wait an hour, and rinse with water after dark drinks.

Is a kit better than single packs?
Yes, for a first course. Whitening is cumulative — stopping halfway gives a partial result.
