I was sent this toothpaste to test and review. The toothpaste is a spearmint flavour which is nice if you don’t like a strong mint flavour but it still leaves your breath feeling fresh and clean after using it although I usually prefer a stronger mint flavour. I used the toothpaste twice a day for 2 weeks to see how well the whitening agent worked and if I’m being honest I only noticed a minimal difference in the colour of my teeth. Maybe with continued use I would see the effect more. Overall I liked the toothpaste but I wouldn’t say it was any different to other whitening toothpastes, it’s just average.

I tend to use the same toothpaste, out of habit and convenience. I don’t tend to buy whitening toothpaste as it normally not as minty/fresh or the taste is not normally something that my kids would use or it’s too harsh for the kids to use. This toothpaste is great it has the right flavour and it’s not too harsh that the children can’t use it (Teenagers). It is gentle enough to be used every day by the whole household thus not incurring an extra charge. And really did give a good clean. My teeth are definitely a shade if not too lighter. A great way to incorporate whitening your teeth without incurring the extra cost and extra tubes of toothpaste laying around. This one does it all, every day doing all the jobs if you want to do. Highly recommend

I really liked the fresh spearmint flavour, it made my mouth feel clean and cool after brushing. However, it dried out my mouth a lot, leaving me feeling thirsty soon after every use. As for the whitening effect, I didn’t notice any visible change even after weeks of use. My teeth felt cleaner but looked the same. It’s a decent everyday toothpaste if you want freshness, but for me, the dryness and lack of whitening results make it not worth repurchasing. Note: I brush my teeth twice daily using an electric toothbrush and soft head.

Colgate Max White Sparkle Diamonds really lives up to its name. It foams up a lot, which makes brushing feel thorough and satisfying, although at first it was almost too much and I had to adjust how much toothpaste I was using. Once I figured that out, it became a really enjoyable part of my routine. The flavour is pleasant and refreshing without being too strong or artificial, and my mouth always feels genuinely clean afterwards. My teeth look a little brighter too, which is a nice bonus. Overall, it is a great everyday toothpaste that feels a bit more luxurious than most, though it definitely works best in small amounts.

I tested Colgate Max White Sparkling Diamonds Toothpaste for 2 weeks. I usually use Colgate Total Toothpaste, so I am used to a good quality around toothpaste. I have fairly good teeth but drink a lot of teeth so they can do with a bit of whitening. I liked the fresh feeling I experienced, and my teeth do look a bit brighter and whiter already. I'm not talking about Hollywood White but a subtle change in colour. I will continue to use and see if it continues to improve my teeth.

A superb tooth paste that leaves your mouth feeling clean. It comes out as a lovely purple paste and once brushing leaves a decent amount of foam around your teeth which allows you to brush effortlessly. It gives a slight minty aftertaste after you’ve brushed - I didn’t feel like the minty taste lasted as long as it should. Your teeth definitely feel cleaner compared to other toothpastes. I didn’t notice a difference in the whiteness of my teeth whilst using this product.

This toothpaste has a fun new toothpaste colour - purple - which I have not used before. It has a good minty taste which is not too overpowering or too strong. It leaves your teeth feeling genuinely clean and your breath fresh. It  works well on whitening teeth and yellowing did definitely reduce over the fortnight I tried it. It foams up nicely and tastes pleasant. I would recommend this as it also appears to be a good price. Great value for money!

I tested Colgate Max White Sparkle Diamond Toothpaste for 2 weeks. It is a purple toothpaste with sphericals of blue that are the spearmint flavour. I enjoyed the flavour although the minty-ness did not last any longer than other toothpastes. I disliked how much the toothpaste foamed when being used and did not notice my teeth being any whiter. Colgate Max White Sparkle Diamond Toothpaste cleaned my teeth and left my mouth minty.
