Featured stories
A sceptic converted!
I bought the whitening kit as a prolific tea and diet coke drinker; my teeth have dulled over the years. I was sceptical as I have bought kits before but found them too faffy, so I never stuck with them. This kit is so much easier. You just paint the gel onto your teeth, pop the light in your mouth for 10 mins and you are good to go.
Amazing results
Having reached 70 a few weeks ago, I was pretty sceptical about the claims I was reading regarding this product. I am sceptical no more. After just 7 days my teeth are looking whiter than they have for years.
Great!
I bought a kit for my son and after only a few uses noticed a difference. I’m off to buy one for myself now. Easy to use with great results!
