Colgate Optic White Toothpaste review

I have teeth that are very hard to whiten - my enamel beds were ruined as a baby by asthma drugs - and this is the first and only whitening toothpaste that has ever had an effect. My teeth are visibly brighter and whiter and I'm only halfway through the tube. For this result, at less than ten dollars a tube, it's a bargain to me. I am amazed! The texture is a little thick and the flavour is very strong, but I don't care, with those results.

Really like this, it did take a few weeks longer to start to make a difference, however now I am nearing the end of the tube I can see my teeth have definitely whitened up, it is also doing a great job of removing stubborn stains that are between my teeth, stains I didn't think it would move! I am confident they will be gone by the time I finish the tube, I will be buying another tube to use as a maintenance brush alongside my normal toothpaste to keep up the nice gleam,

This is the only toothpaste I will buy, I love it.

This toothpaste is pricey, especially for the amount of product you get but for me it's worth it. It has a fresh, minty flavour to it like most toothpastes and leaves your mouth feeling squeaky clean. After using this toothpaste for 3-4 days I started to notice my teeth were whiter and brighter. It was only a shade lighter but I was happy to see results. I use this toothpaste regularly and I highly recommend you try it.

I definitely saw an improvement in the colour of my teeth after 2-3 weeks of using this toothpaste 2 times a day at the least. My teeth were not stained beforehand and were already pretty white, so I didn't expect to see dramatic results, but I definitely noticed that my teeth seemed slightly whiter and shinier after a few weeks.

I like the taste of this toothpaste, and it feels like its getting the job done.. Not like those clear blue/green toothpastes that taste like sugar.

Would definitely buy it again simply as a toothpaste to maintain my current colour as I feel it has some whitening properties but not enough ti justify buying it JUST to whiten my teeth.

This toothpaste is one of the best ones I've ever used. I've found that it has strengthened my enamel, and made my teeth feel stronger. My teeth are also a few shades whiter and sparkle all the time. I've also found that my teeth feel smooth throughout the day and the effects of the toothpaste are long lasting. It is definitely worth the price however it's best to buy it on sale as a tube lasts me a month.

I’ve been using this for a few months now and haven’t noticed my teeth getting any whiter. It does leave a weird feeling on your teeth though, almost like little beady things. My husband has noticed that every time he uses this, it leaves slimey bits on his teeth

Noticed a big difference after using this. It is a bit pricey but definitely worth it! I use this with a blue light toothbrush which works like magic and my teeth have gotten so much whiter! Love it

I have been using this product for nearly four weeks and all I can say is impressive results in the first few days, but not much more after that. The taste is also quite different from other toothpastes as it has a much more mintier taste than usual. I didn't really see four shades whiter teeth in four weeks, more like one or two shades. Maybe with a longer use I may be able to see much whiter teeth. I would really recommend this to people looking for a more affordable option to whiter teeth.
