How we score →Yay
6 experts · Strong agreementWhat the gurus are saying
Got a coffee-and-tea smile that's crept up on you? These peroxide strips earn praise for visibly brightening teeth, from a 10 to 14 day course to a quick monthly touch-up that keeps stains at bay. The UK-based fans are the twist: they swear by genuine US-bought strips and say nothing local has worked. One verdict is mixed, though only on how long the results last, not on the strips themselves.
