Crest 3D Whitestrips Professional White

Crest 3D Whitestrips Professional White are at-home whitening strips that use hydrogen peroxide — the same whitening ingredient dentists use in the chair, at a lower, safer concentration.

That distinction matters. Whitening toothpastes only scrub surface stains; peroxide actually penetrates the enamel and breaks down the pigment underneath, which is what removes years of staining from coffee, tea, red wine and smoking.

The strips grip the teeth so the gel stays in place while you talk or move around, and the formula is enamel-safe when used as directed.

How to use: apply one strip to the upper teeth and one to the lower, aligning with the gum line. Leave on for the time stated on the pack, then peel off. Do not brush immediately before or after.

Frequently asked questions

Will they damage my enamel?
No. The peroxide concentration is set for safe at-home use and the strips are enamel-safe when you follow the instructions. Do not exceed the stated wear time.

What if my teeth become sensitive?
Mild temporary sensitivity is common. Skip a day between treatments and use a sensitivity toothpaste alongside.

Do they whiten crowns, veneers or fillings?
No. Peroxide only works on natural tooth enamel, so dental work stays the shade it was made in.
