Smile Science Harley Street Professional Teeth Whitening Strips for Sensitive Teeth - Peroxide-Free Formula Removes Coffee & Wine Stains - Enamel Safe, Vegan, Mint Flavour - 28 Strips (14 Treatments)

Have been using these strips for just over a week and they are extremely easy to apply. Unlike other strips I have used in the past, I don’t experience any sensitivity or ‘shooting pains’ when wearing or after wearing. Can already see a difference in my teeth. Great results already.

They have gone up by £6 since July that is ridiculous. For the price of £13.50 they were good value - not the strongest whitening effect but good and convenient but now I’m not so sure.

I have now been using this product for six days and was nervous due to the fact that I suffer from sensitive tooth pain. The sensitivity has not been a problem and the whitening effect is very noticeable. A little fiddly to apply at first but after the first two applications I found it easy. Overall, I am very happy with the ease of use and also the results.

I've been using these for almost 2 weeks now and I can definitely tell a difference in whitening. To start with, the strips were a bit fiddly to use and didn't seem to stick to my teeth very well, but the longer they are applied the better they stay. I'm still not quite sure which strip goes on the top row of teeth though, the instructions aren't really clear on that. Overall I'm happy with them and I think they're fairly good value for money.

Used half a packet and looked like staining was reduced. However I noticed that the ingredients were obscured by a white label with the bar code. I removed the label and saw that these contained Sodium Chlorite. I Googled this and there are warnings that this ingredient erodes and weakens enamel. Have binned the rest of the box.

This product does work!

Not noticed the difference that I was hoping for. I also didn’t like the jelly that was left around my teeth after using them. I’m perhaps my expectations were a bit too high!!!

Great value for money
