I'm really impressed with this. It's not a professional teeth whitening treatment or anything, so I wasn't expecting hugely dramatic results - it's just a toothpaste! - but consistent use has definitely made my teeth whiter over time. They don't look like they've been chemically whitened; I'd say it's more like my natural tooth colour made better. And when I stop using it for a while, I absolutely notice the difference. My husband has started using it too now, because he kept noticing how white my teeth were looking in comparison to his!
It's a normal, pleasant, minty toothpaste, it doesn't irritate my sensitive gums, and it gently whitens my teeth, so for me it's a five-star product. It's usually more expensive than many other 'whitening' toothpastes, but this one actually works (at least it does for me), and I always buy it on a good special anyway, so it's well worth it.
I was excited to try this toothpaste, but didn’t do much to lighten my teeth. Really strong taste, and made my teeth really sensitive.
Tips: Don’t use this toothpaste if you have some sort of sensitivity.
