薬用ホワイトニング炭歯磨き粉

As a toothpaste and for cleaning your teeth it does the job, fresh in the mouth and cleans your teeth. I didn’t notice a change in the whiteness or brightness of my teeth

I sure love my coffee and have for years - the proof is on my teeth - or, at least was! After 7 days of brushing twice daily with this toothpaste I noticed the tint was lightening. I am excited to see the effectiveness over long term use. The flavour was pleasant and texture wasn’t gritty. It also didn’t hurt my teeth after.

It’s interesting using using a brown and black coloured toothpaste. I’m very fussy with toothpaste and I quite liked the flavour and texture. My main toothpaste is Colgate optic. My preferred flavour and feeling. I think this will be my second favourite. It’s good consistency and flavour. They genuinely look whiter and cleaner after use. I’m actually really impressed.

The Colgate advanced whiting with Charcoal was a great toothpaste. It has a mild taste and left my mouth and teeth feeling fresh and clean. I liked the micro polishing crystals. I felt like they helped to brighten my teeth.

I've used whitening toothpaste products in the past with very little change noticeable. I was pleasantly surprised to find that the toothpaste worked well. I reckon I lightened my teeth a couple of shades whiter after a week of use. I've kept using it since the first week and I think there are further noticeable changes. I found when I went from a manual toothbrush to an electric one these was a bug change, and this may not have been as significant as that, but it was still a noticeable change. I'd happily buy this again.

It claims to have whitening capabilities but i dont really think it is, it is a good texture for toothpaste, good size tube and the flavour is good, not overpowering, and do not need to use alot at once, but i dont see any change in whiteness of teeth

This is a great tasting toothpaste and it does whiten your teeth. The toothpaste also leaves your mouth feeling fresh. At first I thought it was cool that it was orange and grey stripes. However it does go an unpleasant colour after a few uses. But however, I would recommend this toothpaste. It is very good. I hope I see this in shops very soon.

Great product, it is a nice taste and cleans the teeth well, would recommend this to family and friends, saw a improvement in whitening my teeth and I think after a longer period you would notice the difference more

I love Colgate toothpaste and this one is no exception. It made my teeth feel clean and my mouth refreshed. Unfortunately, I did not see any improvement in the whiteness of my teeth, but besides that, it is a superior toothpaste in every other aspect. I also love that it is vegan. Good toothpaste, I recommend it!

Overall basic toothpaste, I did not notice any benefits of the added charcoal or "micro crystals". I believe these are just marketing gimmicks. My teeth are not noticeably any whiter after using for 7 days.
