FAQs

Are Crest Whitestrips safe to use?

Before you buy, you'd be totally justified in wondering: are Crest Whitestrips safe to use? Well, according to Dr. Stoess-Allen, there's been no evidence that any of its ingredients harm tooth enamel. Hydrogen peroxide is generally to blame for increased sensitivity while using whitening strips, which Dr. Stoess-Allen advises choosing products with 10% or less of this ingredient. And if you're prone to sensitivity, it's always best to start with a lower concentration of hydrogen peroxide. The Crest 3D White Professional Effects Whitestrips fit the bill here, which is why they topped our list of the best teeth whitening kits.

Is Prime Day a good time to buy oral care products?

Each year, we expect 20-50% off the best oral care products from Crest during Prime Day, and this year is no different. Amazon is already a great place to buy dental hygiene essentials like toothpaste and floss, but buying them in bulk during Prime Day is a great way to save yourself time and money.

How can I make the effects of Crest Whitestrips last longer?

To get the fullest benefits from using a Crest tooth-whitening kit, take a look at what's in your diet. Consider abstaining from foods and liquids that cause yellow teeth — there are the obvious ones like coffee and tomato sauce, but remember: anything with strong pigments or acidic content can stain your teeth. Fruit juice, dark-colored sodas, curry, balsamic vinegar, and gummy candies are a few common offenders.
