Crest 3D Whitestrips Professional Effects 20 Treatments

Crest 3D Whitestrips are the most widely used at-home whitening treatment, and Professional Effects is the dentist-level strength. Each thin, flexible strip is coated with the same enamel-safe hydrogen peroxide gel dentists use, moulding to the teeth to whiten below the surface.

Worn 30 minutes once a day, the full 20-day course removes 14 years of stains, with visible results after three days and whitening that lasts up to 12 months. Advanced Seal technology keeps the strips in place so you can talk and drink water.

Apply to dry teeth, press, wait 30 minutes and remove. 20 treatments (40 strips).
