Today's best Prime Day deals come to a close at midnight tonight. In the meantime, one item we're witnessing surge to the top of the most-bought list is the Crest 3D Whitestrip kit. During the last day of Amazon's Prime Big Deals Days, you can score a pack for just under $30.
Crest 3D Whitestrips remain the number one dentist-recommended option for at-home teeth whitening. New York City orthodontist Dr. Janet Stoess-Allen, DMD, previously told Business Insider that she often suggests them to her patients. Our staff pick, Crest's 3D White Professional Effects Whitestrips, are 35% off. We've found them easy to apply and saw a visible difference after regular use.
Crest makes many different versions of Whitestrips — and finding the best teeth whitening kit for you will depend on your needs, goals, and budget. The good news: there's a Crest Whitestrips deal for everyone during the Prime Day sale.
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.
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. For more discounted grooming essentials gathered all in one place, check out our guide to the best beauty deals.
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.
