Dentech whitening gel use the exact same whitening ingredient as used by your dentist. Whitening gel has been proven to be extremely safe and highly effective.

As you consume staining foods and drinks, smoke, or just get older, your teeth absorb dark, staining particles, which over time give a dull, yellow, or even grey appearance.

Dental whitening gel works by penetrating the tiny pores of your tooth enamel and turns those stains white by oxidizing them. The gel does not interfere with the tooth enamel structure in any way.

In a recent study by the University of Rochester, USA, teeth whitening has been shown to be safer than orange juice! Concentrations of the active ingredient used in professional and over the counter teeth whitening processes don't cause significant changes to tooth enamel, according to the US researchers. Conversely the researchers found that an everyday practice such as drinking acidic fruit juices can have significant negative effects on the hardness and the roughness of tooth enamel.

The scientists, led by Yan Fang Ren at the Eastman Institute for Oral Health at the University of Rochester , investigated the effects of whitening gel on tooth enamel. According to the team, when compared to orange juice the whitening gel did not lead to any significant changes in the hardness of surface enamel.

This product is great! I've used it about 10 times now and that's all it took to get my teeth looking really white. I am a dental student myself and was always wondering whether the over-the-counter products actually worked - I decided to whiten just the top jaw first and the difference was incredible! The fact is that the gel contained in the kit is exactly the same as dentists use so it makes you think why people pay over £200 to get the dentist to do it? I know for a fact that it doesn't cost dentists any more than £25 for the gel they sell to you and the results won't be any better than this... i'm a little worried for the future loss of earnings lol :-)

I just have to write and tell you what I think of your whitening. I am very happy and really satisfied. I have been whitening my teeth for five days now and I can see a massive difference. Usually, advertising is exaggerated. But it is incredible. MY TEETH ARE WHITE AGAIN.....And I was a little concerned about shooting pains (there was a slight sensation of pain the first two times I used it but after that, there was no discomfort whatsoever). I am more than satisfied and will be spreading the word to everybody. Yours truly, Gaby
