Whitening your teeth at home is already an affordable alternative to in-office treatments, but today it’s even cheaper: Crest 3D White Professional Effects Whitestrips are $20 off at Amazon, making them just $28. This kit has nearly 40,000 five-star reviews on Amazon, and when we spoke to dentists earlier this year, they came out as the top recommendation for at-home whitening strips. “They have the ADA seal of acceptance, which means they have been evaluated scientifically for their safety and efficacy by the American Dental Association,” says Dr. Ben El Chami, the co-founder and chief dental officer at dntl bar. He’s also seen the results on his own patients, as have two other dentists we spoke to. The strips are made with hydrogen peroxide, which is the No. 1 ingredient for teeth whitening. The 20 Professional Effects treatment strips gradually brighten teeth over time. The box also includes two one-hour express treatments that deliver same-day results. This is a one-day deal only, so don’t dillydally — order them now before they’re back at full price.
