If, like me, you’ve watched your fair share of American sitcoms, then you’ll notice one thing all the actors – from Zooey Deschanel to Matt LeBlanc – have in common: pearly white teeth. It’s no secret that our neighbours across the pond (or at least the ones in the media) have superior gnashers but, in 2025, it doesn’t have to be that way.
Though regulations on hydrogen peroxide (one of the most popular ingredients in teeth whitening kits) are less strict in the US, it’s still possible to achieve a brilliant smile here in the UK. In fact, I’ve been testing Gleam’s at-home teeth whitening (was £39.99, now £24.99, Gleamteeth.co.uk), and there’s no doubt it’s brightened the ‘ole ivories – but more on that later.
