If you’re one of the many, many people who want a brighter smile but don’t want to splurge on a beaucoup pricy teeth-whitening treatment at the dentist office, we’ve got good news. Removing surface stains and improving the overall appearance of your teeth is possible by making one simple switch: changing your toothpaste.

Dr. Mike Wei is a NYC-based cosmetic dentist with more than 230,000 Instagram followers. He often posts compelling “before” and “after” photos of his patients, so we asked him our most pressing teeth whitening question: What toothpaste do you recommend for people looking to get a brighter, white smile fast? His answer? Colgate Optic White.

According to Dr. Wei, toothpastes like Colgate Optic White that contain hydrogen peroxide can effectively help to remove surface stains and brighten up your choppers in just a few weeks. He adds that Colgate Optic White is also gentle on tooth enamel and formulated with fluoride, so it’ll help ward off cavities in the process.

If you’re serious about brightening your smile ASAP, Dr. Wei has a few more helpful tips. He encourages people to brush with a whitening toothpaste like Colgate Optic White at least twice a day, or after meals, and to floss regularly. He also recommends avoiding smoking, drinking coffee and tea, and eating staining foods like berries. And if you want to go the extra mile, add a whitening mouthwash to your oral hygiene routine.

Like Dr. Wei, shoppers on Amazon have given Colgate Optic White overall positive ratings, with over 26,000 of them bestowing five-star reviews.

“Makes teeth white again,” raved one of them. “Works great! Teeth feel fresh after brushing and very clean. Have used for a few weeks now and can definitely tell they are much more white.

“Keeps teeth white,” said this smiling spouse. “My husband and I get comments all the time about how white our teeth are. We have used this toothpaste for a little over a year and it definitely whitens our teeth! It is hotter than most minty toothpaste, so just keep that in mind when buying.”

This shopper cautions that Optic White may actually work too well! “This toothpaste is good for whitening and I think I can see the change!” they said. “But sometimes I feel it is a bit too strong for my teeth, so I use this and other normal toothpastes without whitening effects. The taste is good, freshness is not the best but good enough.”

If you want to try an at-home whitening option before splurging on an expensive in-office treatment, then add Dr. Wei’s recommendation to the cart of your next Amazon order.
