Crest 3D Whitestrips Levels 8 in 1 Week

Crest 3D Whitestrips Levels 8 in 1 Week is the fast option in the range — a short course designed to lift teeth 8 shade levels in seven days, which makes it the one to reach for before an event.

It uses hydrogen peroxide, the same whitening agent used professionally, in a strip that grips the teeth so the gel stays where it should. The formula is enamel-safe when used as directed.

How to use: apply one strip to the upper teeth and one to the lower along the gum line, once a day for the time stated on the pack. Complete all seven days.

Frequently asked questions

What does "8 levels" mean?
It refers to steps on a dental shade guide — the scale dentists use to describe tooth colour, not a percentage.

Is a one-week course harsher than a longer one?
It is more concentrated, so sensitivity is more likely. If your teeth are already sensitive, choose a longer, gentler course instead.

How long does the result last?
Several months with normal care. Coffee, tea, red wine and smoking bring the stains back faster.
