What is the principle of action of Crest Whitestrips?
Crest Whitestrips are thin, flexible strips coated with a whitening gel containing peroxide. They adhere closely to your teeth for better contact.
How to apply Crest Whitestrips?
It is recommended not to brush your teeth immediately before or after applying the strips. Open the sachet and take out the strips. Peel the strip off the liner and align it with your gum line. Press gently for better contact with your teeth. Fold the remaining part of the strip behind the teeth to secure it. Wear the strips for the indicated time, then remove and dispose of them properly.
What if I swap the strips (upper and lower)?
We do not recommend swapping the strips. Although they will still work, each one is designed to cover a specific part of your teeth. The shape ensures they stay on the teeth that are visible when you smile. If you swap them, they will cover a smaller area and result in less whitening.
When will I start noticing results with Crest Whitestrips?
The first results may vary from person to person, but most notice changes around the middle of the treatment, with full results at the end. If you need fast whitening, choose Crest 3D White Glamorous White Luxe or Whitestrips Professional Effects, which show results in just 3 days.
Can I reuse Crest Whitestrips after finishing the treatment?
Yes. You can use Crest Whitestrips up to twice a year to maintain your white smile.
How long will my teeth stay white?
The duration depends on several factors, including how often you drink coffee, tea, cola, red wine, or smoke. Crest 3D White Glamorous White Luxe and Professional Effects keep your smile whiter for up to 12 months. If you consume a lot of these products, Crest 3D Stain Shield strips can provide extra protection with a short 5-minute daily application.
Are Crest Whitestrips harmful to tooth enamel?
Crest Whitestrips are safe and effective when used as directed. All available data shows that whitening strips do not damage tooth enamel. They contain the same active whitening ingredient dentists use.
What if I miss an application?
Missing one, two, or even three Crest Whitestrips applications will not affect your overall whitening results.
