Colgate PalmoliveOw Renewal Tp 3Z Cs Sp High Impact White, 3 Oz (B082JBVYNT)

This toothpaste is the best. I've been using this constantly for well over a year and the whiteness is dramatic. Personally, I find the most effective way of using this is to brush for two minutes then afterwards do not rinse your mouth out. Retain the toothpaste/saliva solution in your mouth for as long as you can manage after brushing. This is so the solution is in contact with your teeth for longer than your brushing time. Your family may find you a little odd walking round the house unable to talk while the solution is in your mouth, but when you spit it out (give it around 10 minutes if you can manage) you will immediately see the difference. After a year of using, it looks like I have veneers.

Opened and half empty. Don’t buy this

The best toothpaste ever. Tastes ok, mouth and teeth feel clean

I haven’t been using this long enough to say if it whitens your teeth. However I think £16 is a bit to steep for toothpaste, I’ve heard from people that other cheaper products are far more effective. While it does leave your teeth and mouth feeling very clean I wouldn’t buy again simply because of the price. I bought euthymol toothpaste for about £6 and it does the same job so I’d recommend that a lot more.

i’ve tried a lot of whitening toothpastes and a lot of them i never see results but with this one after using it for 2 weeks i could instantly tell a difference and not only me but my family did too so would recommend to anyone looking for a whitening toothpaste

Helps to whiten only down side was the tube was only half full

I have pretty white teeth already so I get it wouldn't make a massive difference but I actually think my teeth have started to look yellower using this.... it has had zero whitening effect whatsoever. I'd try a cheaper alternative before buying this.

This toothpaste is very good, but the listing states 3% hydrogen peroxide, whereas the product itself is actually 5%, which is even better than what I ordered, so I’m not sure what that’s about but it doesn’t matter. It’s an amazing toothpaste though, exactly like the ones in the USA, (it is an American product by the looks of the label and packaging).
