Smile Science Harley StreetProfessional Teeth Whitening Kit - Whitener Kits & Aftercare - Up to 8 Shades Whiter - Vegan - Tooth Whitening - Whiter Gel

A brilliant purchase from smile wife & amazon after seeing some youtube videos of the smile sciences blue light teeth whitening machine & gel product which worked for them which they seemed to be honest reviews of the product from them so i thought that i would try this product as i have yellowish teeth & did it work for me, it sure did & my teeth get whiter everytime i use it, I have read other people's reviews who said it doesn't work for them but say that the reason might be that they should use it for more than the recommended 20 minute time from smile sciences which i do mine for 30 minutes for the shortest period & sometimes up to 1 hour depending it i'am just relaxing & just getting into watching 1 hours worth of games of thrones where taking it out after 30 minutes just isn't possible so try using it when you do for the same time period as i do which hasn't damaged my teeth at all & which i 'am happy with the smile sciences product & extra whitening gel syringe items that i use for my teeth too. 🌠🌠🌠🌠🌠💖💎😀

I had high hopes for this product but not seeing any results yet. I am only on day three of the ten day journey so perhaps I am being a bit impatient with seeing any improvement. I find that immediately after applying the pre-stain removal and then the gel, my teeth do look brighter and more shiny but after a few hours they just go back to looking the same as before.The box is well presented and the products taste good which is a bonus. The instructions on the back of the box would have been easier as an insert, as the first time you use it it's a bit annoying to keep having to shut the box and flip it over to check the next step (but not a big issue).If after the full treatment I see positive results I will happily come and write another review!

Tried a few cheap kits but this one is actually whitening my teeth. Mine wasn’t to bad before but even I can nothing the difference after a few sessions. Kit is smart easy to use 15 mins a day and brushing solutions for your teeth. Tooth paste/tooth gloss/ pre stain remover all taste is ok nothing is gross. The after teeth gloss really makes your teeth shine in the light. Basically if you want too Whiten your teeth on the cheaper side tie is the kit to have. 10/10

I found this product straightforward to use, although it would have been even easier had there been images along with the written instructions. I find pictures easier to follow personally. The treatment was suitable for my sensitive teeth and didn't feel too harsh,The overall result I found was one of brightening rather than long term whitening, but I still consider this good value for money.

Now it could be a massive coincidence, but it could also be something to do with this product. After using for 4 days I was driving when I noticed what felt like food stuck to a wisdom tooth. I picked it and out of my mouth came half a wisdom tooth. Now these are big beasts, and I have no fillings nor gum disease, and after seeing the dentist post tooth fracture still don't require any. So somehow something weakened my tooth enough to allow for a below gum line fracture. I find it very odd that this happened mid treatment with this kit. Hasten to add I never went back to using this kit and can't say that they 4 days of use produced enough of a whiten to warrant the surgery I now need to remove the remainder of the wisdom tooth that is too entwined in nerves to have it done at the dentist. Joy.

The product is not fit for purpose. It does not work at all. I am extremely disappointed. The product states that teeth can go up to 8 shades lighter after the treatment. I expected to see at least reasonable results. However, my teeth did not even go one shade lighter, they look the same as how they were before the treatment. I have wasted my time and money. Furtheremore, customer service at Smile Science Harley Street are not helpful at solving consumer complaints.

I am impressed with this kit, and with the results obtained. Pleasant tasting, mild mint flavoured. I found it easy to follow the instructions, and it was not too uncomfortable to wear the device for the short fifteen minute intervals. My teeth do look brighter, and my mouth feels refreshed. I have a new found confidence to smile more.

When first opening this box, it's all a bit mystifying, but an examination of the contents makes everything clear-what is to be used when etc., even if the text on the back of the box is a little bit small for these eyes.The first time you use it, it feels a little bit strange, a bit like putting a baby's dummy into your mouth I suppose. The taste of the whitening gel is quite pleasant-minty and clinical.The big question is, of course, does it work? Well for me it did improve the whiteness of my teeth a little bit, but not to the '8 shades' (whatever that means) level. Just don't expect a Tom Cruise Hollywood smile!
