The question I’m sure everyone wants the answer to is, does this toothpaste immediately change the whiteness of your teeth? The answer is “yes”, but it’s extremely short-lived; if you use mouthwash or have a drink straight afterwards then the effect is gone, so I wouldn’t buy this with the hope that it’ll offer you anything other than a quick brighten that’ll last at most I’d say half an hour. As you brush, the blue bits disperse within the toothpaste turning it extremely blue, so you’re left with a very thick, blue foam that temporarily stains your teeth and the surrounding gums. You’ll want to make sure you thoroughly rinse it away so you don’t have a blue line around your mouth which can look a bit strange (live it, learn it…) but apart from that, I’d say as long as you’re not hoping for miracles from the toothpaste then this isn’t a bad buy as I do feel it works well as a gentle stain-removing toothpaste. It’s available now for £4.49 – link.
