Smile Science Harley Street Reviews 

Have never had such white smile.The kit works brilliantly and tastes good too with a mild minty flavour. Excellent service and fast delivery.

Quick and efficient delivery. Will buy again

Mouth tray is so shallow it only comes into contact with bottom 1/3 to 1/2 of tooth. Not sure how this is expected to whiten the whole tooth.

got just what i ordered at a great price and results are looking promising.

Can see the difference already 😁 I’m happy with this product.

Been using for four days,yet to notice a change

Thought I'd whiten my teeth whilst after wearing a face mask for so long. Saw results after 2 days, really happy with my purchase. At least something is keeping me smiling. Excellent service to as arrived next day.

Really quick delivery and I have literally seen such a difference in 2 days of using it!

I have used many different 'supposedly' teeth whitening strips, pastes, gadgets and never had a result, so I was a bit reluctant to try Smile Science, I read reviews on various different platforms and they were all positive so I took the plunge and let me tell you I am not disappointed in any way, after only day 3 of using the LED light activated kit I have seen a big difference, at least 2 to 3 shades, it's a 10 day treatment process and says it can whiten your teeth upto 8 shades whiter! So, so far so good, I can't wait to see the finished result!! I most certainly recommend Smile Science Harley Street Professional Teeth Whitening Kit LED Light Activated (for sensitive teeth). The kit I got has a pre-stain remover liquid and brush that makes my teeth and mouth feel so ready for the lightning process, it has a really nice minty tastes, leaves no nasty aftertaste, 2 x 5ml syringes pre-filled with whitening agent gel, 2 x syringe tips for a precise application and to stop you from squeezing too much gel out and wasting it, 1 x LED plasma light, 1 x integrated mouth tray, 1 x 7ml pre-stain remover.
It's so easy and fuss free to use, just 15 to 20 minutes and you're all done. The mouth tray can be detached easily for cleaning, comes with batteries so no having to charge before each use.
Massive thumbs up from me!! Thank you Smile Science for giving me the confidence to smile big again!!

Whilst both the strips and the foam cleaner and whitener have proved to be effective, the delivery systems are not.

Firstly, I was saddened to discover that manufacture was in China. With this country's aggressive use of animal testing and disregard of human rights I had expected a more ethical approach to choosing a manufacturer by this company.

Regarding the product itself, The foam appeared to be little more than a marketing gimmick. It was unpleasant to use and kept falling off the brush. The instructions for the use of the whitening strips appear to be incomplete. I finally worked out how to affix the second strip to my lower teeth but had problems with it coming loose, often as a result of it attaching itself more firmly to the edge of the upper strip than my teeth.

So, effective product that needs to go back to the design and manufacture teams.

Fast next day service. I was excited to try out the refill kit and wasn’t disappointed. I saw results 3 shades whiter teeth after only a couple of days. The difference with this kit is the pre stain remover that felt like my teeth were prepped for the treatment. Really nice minty taste too.

Great service from Smile Science as received my pen the following day.
Pen was very easy to use and teeth definitely look whiter as stains gone.
Would recommend company and products.

Amazing product best whitening pen on the market in my opinion my new forever pen

The best teeth whitening product I have ever used and I have tried a lot!
Fabulous results in a short period of time.
I highly recommend.

Great product. Excellent prices especially in the sale. Good results from the product

I have noticed no difference with this “whitening” pen! Have been using it for couple of wks now & my teeth have not changed at all. Wasted my money & would not recommend!😕

Still not received my 3rd smile science box which was a xmas present .Saying the house number wasn't on the order even though 2 had been received previously. Very disappointed

Did not see any difference after using this product for 10 day's. It left me with sensitive gums, package came with plenty of products which looked good and value for money, but with no end result.
