35% Teeth Whitening Gel Refills Bleaching Gel 20 PCS 3ML Teeth Whitening Gel with 4 Pcs 3ml Remineralization Gel Tooth Whitener Gel Works with Teeth Whitening LED Light and Tray

Having previously had Philips zoom from the dentist, this was a 10% of the price, and I think worked better without the burning!

It’s okay but not the most effective gel but it will maintain the teeth colour, it hasn’t increased the whiteness of my teeth.

Very good very white teeth

You get what you pay for, I have bought dentist issued gel and it worked brilliant, this was bought for a top up , I don’t think it’s as strong as it says but it definitely does work. You get the bubbling sensation and a clean white smile on areas where the enamel was previously yellow. Depends on how yellow your teeth are , but definitely works in some way.

Firstly, why do I have 2 different coloured gels? I'm not noticing any difference, and I am leaving it on for 2 hours at a time rather than the 15-30 minutes they recommend. I paid my dentist £180 for a teeth whitening kit which included them making me a gel tray professionally molded from my teeth. Their day use gel was 35% CP and the night use gel was 16% CP. When I used either of those, I could feel the chemical working, and my teeth becaming very sensitive. I was told not to eat for at least 2 hours after each treatment. The results were great. The problem was, I was only given 3 weeks supply, and another 3 weeks would cost £50. I do not feel any reaction on my teeth after using this budget gel. It's probably only 4% CP if any. I thought I would save a few quid, but looks like I've wasted a few instead. I'll have to purchase directly from my dentist. At least I know what I'm actually getting.
