Always striving for whiter teeth, I used the Colgate Optic White toothpaste for two months, with no visible difference in the whiteness or brightness of my teeth. I used this toothpaste morning and night, and sometimes cleaned with a standard toothpaste afterwards as I didn't feel minty fresh with the Optic White alone. I noticed no sensitivity after using this product - something I did experience with the Crest Whitening Strips.
Two months after using this toothpaste I had been reading reviews and saw lots of warnings about whitening toothpastes (not just the Optic White) making people break out around the chin area. This was at a point where I had very clear skin, but had had a month of 5-8 blemishes all in one spot, on one side of my chin. I immediately stopped using the toothpaste, and they cleared up pretty quickly. I don't want to say that it WAS the toothpaste, but it may be something to watch out for.
The bonus to using this toothpaste was that I took more care brushing my teeth. Envisioning whiter teeth certainly makes you brush for longer!
In theory this sounds good. 3 shades whiter teeth? Yes please!
I love the metallic red tube this comes in it looks pretty and makes me want to use it. I love the real minty flavour of this it's quite strong and reminds me of the imperial mints. It leaves my teeth feeling very clean for hours afterwards better than any other toothpaste I have used. But I will unfortunately never use it again. It has left my teeth and gums so sensitive nearly every tooth has been aching and my gums have felt like they are burning. It's really thrown me because I hardly ever get sensitive teeth generally only if I eat ice cream too fast. I think it could be the hydrogen peroxide that's causing the sensitivity because I have never experienced this before with normal toothpaste. Never ever again! I will leave the whitening to the dentist.
