I suffer from mouth sensitivity due to gum disease many many years ago. I shy away from teeth whitening as most of them were reported to hurt if you had any sensitivity - until now. I saw this product on QVC, the TV shopping channel. It was being sold at a special price but more importantly, it had been developed for people who had mouth sensitivity. Upon arrival I was a bit apprehensive but I wanted whiter teeth. I was pleasantly surprised, I did not experience any pain at all and the more I used it the whiter my teeth became. I’m not sure you would achieve that really bright white but certainly you would achieve a few shades whiter and once the shade of white is achieve you only have to use it as a maintenance product. If you initially purchase with QVC they usually have a 60 day return policy, this provides total peace of mind in case it doesn’t work for you. I will keep using this product and obtain my refills from Amazon as its more cost effective

Pretty standard teeth whitening product but a little disappointed with the strength of its whitening capabilities; thought it would be more powerful but, on the plus side, it did not cause any sensitivity like other products I have used. 4/5 stars.

Love this product as it really works, easy to use and you can see the difference from first time using and no sensitive teeth

I was disappointed with this teeth whitener. It sounded great, but I haven't noticed any difference in the whiteness of my teeth. I also felt it was expensive given there were only 2 small syringes of whitener.

Used this for a while, though I don’t have a smile like Ryland, I think it keeps the stains at bay

Doesn't work, a whitening toothpaste would be better!

Have been using this product and I am a smoker who drinks coffee and this has lifted the brown/yellow stains. It’s a very easy product to use and doesn’t have an unpleasant taste like someone I have used before. I love how it comes with the whitening chart- will defiantly be buying more.

Just wanted something to lift light staining on my front upper and lower prior to going to a wedding .....as I knew there would be quite a few photos taken ....I did the job nicely .....good value 😀🙏
