Smile Science Harley Street Reviews 

This is a really good product for tooth whitening. I recommend.

The products look great and now my teeth look great. Amazing quality and was simple to use.

I received the PROFESSIONAL TEETH WHITENING SET, which contains an LED light, pre-liquid treatment, gel, toothpaste, and gloss. I did expect this to take a long time to add into my self-care routine, but it fitted in seamlessly and without much effort once you set the products up.
I found after a week of being consistent that the results were starting to show. I then had compliments after a month. Bearing in mind I work in the tea and coffee industry, it was able to tackle the tannins very well!
I honestly wouldn't go to anything else as this ACTUALLY works. Money had to work harder for us now and we won't throw it away after gimmicks, this is NOT a gimmick.
P/S I had to contact customer service for aquestiom and they could not have been more polite or helpful and I was in contact with a human not a machine!

Very impressed after the first use! My teeth looked and felt much cleaner after the first use and already look whiter than before. I shall buy this again.

Good quality items that do exactly what they claim to do. No sensitivity to teeth or gums.

I must say, I have been extremely impressed with the products and service from Smile Science. I have used a number of products from them, they are dispatched immediately and produce great whitening results.

The delivery was fast. The products were good quality and the price was very reasonable.. I would definitely be using these again, thanks you .

These teeth whitening strips are a life saver. Never again will I be self conscious about my yellow stained teeth, they are super effective and work pretty quickly. My teeth are also so sensitive, these don’t affect them at all, very very impressed and will definitely be purchasing another set in a few months. Thank you!!

Fast delivery, easy product to use with clear instructions! Whitened my teeth quickly and had loads of comments on how white my teeth are!

Great easy to use kit
Professional looking
Quick delivery

I’m so happy I found Smile Science. For time I was trying to find a good whitening pen, and after 2 weeks using it, I can finally say is the best one I’ve ever tried. I’m surprised by the results! Definitely I’d keep it as part of my essentials!!!!

Bright Smile in a Pinch!

I’ve been using this whitening pen for about two weeks now, and I’m genuinely impressed with the results. I was looking for a quick, low-maintenance way to touch up my smile between dentist visits, and this little pen really delivered. I saw a difference after about 3 uses, especially on stains after drinking coffee or tea throughout the day.

Very impressed by the PAP Whitening Powder: it is quick and effective!

Easy tooth whitening pen. Since I have started using it, I can already see the results. I find the silicone nozzle with the bristles easier to use than the whitening gels I have used in the past. As someone who drinks a lot of tea, I find it helpful to have a quick and easy solution to keeping on top of those yellowing stains and this does the trick.

I’ve been using the PAP Teeth Whitening Powder from Smile Science Harley Street for a couple of weeks now and honestly, I’m really happy with it. I drink a lot of coffee so my teeth have always had some staining, but I’ve already noticed them looking a bit brighter.

It’s super easy to use and best of all, it hasn’t made my teeth feel sensitive like other whitening stuff I’ve tried in the past. I wasn’t expecting a huge difference so quickly, but I can definitely see an improvement.

Would recommend if you’re looking for something gentle but effective.

Loved the tooth whitening pen, it's really accessible, affordable and easy to use! Great to have something in the house to touch up your smile and some of my more stubborn yellower teeth are finally looking bright white!

Teeth whiting pen was delivered very quickly, I love that it only takes 10 minutes to work as most you have to leave on for ages! After a couple uses I have noticed a difference so overall super happy!

The "Professional Teeth Whitening Kit" is a waste of time. With the catchy headline & promise of up to 8 shades lighter I would have thought I'd have seen even some positive change to the colour of my teeth after using the full 10 day course (even if only by 1 shade). I used their provided whiteness scale and started at a level 4. Now 10 days later I am still at 4. I compared in various lighting conditions just to rule out lighting being a misleading factor to the results, but the results speak for themselves,,, This product does not work as promised. Save your time and money by looking at a different product. I can't help but feel the 5 star ratings are either for another product in their range or just fake. Furthermore the mouthguard is an absolute pain to re-install after cleaning, with cheaply moulded and deformed rubber which needs to be wrestled with to stay on the light source. I have a cool, blue light torch now though :)

After trying many different teeth whitening products this one was by far the best.would definetly recommend it.
