I inherited many attributes from my mama: her blue eyes, her love of running, and her beaming Southern smile. Growing up in Virginia, my mama learned that a smile is the best accessory to any outfit. She made sure to polish her pearly whites before horseback riding and playing croquet. This fourth-generation Virginian passed on her Southern beauty tips to me, including her secret to a brighter smile.

It's the Crest 3D White Professional Effects Whitestrips—a teeth whitening kit that's so good, it's accumulated over 14,000 perfect ratings on Amazon. Reviewers claim that the at-home treatment removes years of coffee, wine, tea, and cigarette stains, and that it's even better than going to the dentist. Best of all, the teeth whitening strips are 44 percent off for Amazon Prime Day, costing just $28 now through October 14.

The strips are designed to provide a professional-level teeth whitening treatment by using the same enamel-safe whitening ingredient found at the dentist's office. Many other teeth whitening strips on the market only remove surface-level stains, but Crest 3D White Professional Effects Whitestrips eliminate the set-in stains under the enamel surface for more lasting results. 

Application is simple and straightforward. Place the thin, delicate strips on your teeth for 30 minutes a day for a noticeably whiter smile in under a week and full results in about 20 days. Each strip comfortably molds to your teeth with a secure, non-slip grip, so you can kick back and relax until the treatment is over. The big box contains 44 strips, which is enough for 20 whitening treatments.

My Southern mama has sworn by these Crest 3D White Professional Effects Whitestrips for years because they brighten her smile without irritating her sensitive teeth and gums. She's not alone in her assessment: Reviewers are calling them "the best whitening strips ever" and "worth every penny."

"I couldn't believe the incredible results," one shopper wrote. "The first set I used almost completely removed 50 years of stains, including those from 40+ years of smoking."

"Over the holidays, I indulged in too much coffee and red wine, and my teeth suffered for it," another said. "I noticed results after the first time I used these whitening strips, and my teeth got about three shades later."

This Amazon Prime Day, you can score up to 50 percent off teeth whitening kits and toothbrushes from Crest and Oral-B. Here are some other sales worth your attention.
