“This whitening combo includes Supersmile Toothpaste and a Whitening Accelerator, so you barely need to change your routine to give your pearly whites an extra boost. The formulas work together to dissolve the stain-attracting protein that coats teeth, making your teeth cleaner, brighter, and less likely to suffer from bacteria growth.”

“If you have already invested in a professional whitening treatment, you’ll want to make another splurge on this toothpaste. It’s designed to maintain the results of bleached or bonded teeth. The ingredient spotlight is on Calprox, which gently dissolves a protein called a pellicle that can attract stains, and also prevents bacteria growth.”

Byrdie

“Look, I know a toothpaste is a toothpaste is a toothpaste, but trust me, this one really, truly works in just a few days of twice-daily (i.e. usual) brushing, thanks to its hefty dose of stain-dissolving calcium peroxide.”

Marie Claire 

“ Why we like it: ...the gentle formula fades surface stains over time, making teeth look subtly whiter—and it strengthens tooth enamel, too.”
