A brighter smile is one of the most sought-after beauty goals, which explains the ongoing (if not increasing) appeal of the best teeth whitening kits. Whether staining comes courtesy of coffee, red wine or simply everyday wear, these treatments promise a fresher-looking smile without the cost of a dentist appointment – but not all of them are worth your time.
Used alongside a good whitening toothpaste and electric toothbrush, the best teeth whitening kits can help lift surface stains and noticeably brighten your smile at home. Most rely on hydrogen peroxide, though in the UK that ingredient is tightly regulated, which is why formulas here tend to be gentler than those sold elsewhere, such as the US.
