Smilie works because it is designed to actually break down and remove stains, rather than temporarily masking yellow tones.

Developed by dentists, the formula contains 6% hydrogen peroxide, an active whitening ingredient that targets stubborn stains caused by coffee, tea, red wine and everyday life. The precision pens allow the gel to be applied directly and evenly to each natural tooth, while the timed LED mouthpiece makes every 15-minute treatment simple and consistent.

The result is genuine whitening without the sensitivity commonly associated with traditional whitening. In our study, 96% of participants noticed visible results after their first treatment, while 99% experienced no sensitivity.

I honestly didn't think my teeth could get this white! I was hoping for a bit of a difference, but the results completely blew me away. The whole kit was really easy to use, and I didn't experience any sensitivity, which was a huge bonus. It's given me so much more confidence to smile. I couldn't be happier with the results and would definitely recommend the Boost Whitening Kit to anyone thinking about whitening their teeth!

Really impressed with the entire process from start to finish. Easy to use system, zero sensitivity and a fast result. I chose this one over others as I like the fact it was developed by dentists. Highly recommend

Exactly as I'd hoped for! I have tried every product in market from supermarket toothpastes to in-chair whitening and nothing, and I mean nothing compares to Smilie's Boost Whitening Kit! It's the perfect balance of giving you the result you're after without leaving you in pain. In chair whitening gives a fast result but its super painful and cheaper products are a waste of time and money. 100% recommend Smilie, don't think - just do!!

It might sound a bit silly at 68, but I still want to look my best. My teeth were quite stained, as many are at this age and Smilie has made such a difference. What I love most is how simple it is to use, just as the instructions and reviews promised. I was a little nervous at first because I have sensitive teeth, but I’m happy to say it didn’t cause any discomfort at all and the taste was pleasant too. I highly recommend this product to anyone thinking of giving it a go. Thank you, Smilie, for giving me back my confidence!

I received my smile package yesterday. I used the strips last night and then the toothpaste this morning and already a huge change. I drink coffee a lot and these other toothpastes couldn’t get rid of my stains, I’m so impressed with this product. Can’t wait to use the Boost Kit!

OMG so impressed with your product. We ordered for our wedding prep and this is the result 10 days in! It was such an easy product to use and we found it easy to keep up with as you can do it from home, in front of the TV our around the house. After my wedding, my husband said the first thing he noticed when I walked down the isle was my smile!

The

Difference

Clinically-backed beauty tech designed around you. Smilie exists for the in-between moments. For the ritual-makers. For people who want real results without the clinic.

Step 1 Brighter and dry

Brush and floss, then make sure your teeth are completely dry. A dry surface = better gel contact.

Step 2 Apply the gel

Twist the pen until gel appears. Apply a generous layer to the front of your top and bottom teeth.

Step 3 Insert, Activate & Accelerate

Pop in the mouthpiece and hold the button for 3 seconds. The light will switch on to let you know the treatment has started. The LED switches off automatically after 15 minutes. Repeat for up to 30 minutes total.

Step 4 Rinse and you're done!

Repeat daily for 7 days to complete your first course. After that, one maintenance treatment a fortnight keeps your results going.

How to Use:

15-30 minutes per day for 7 days.

Questions?
We’re here to help.

We know you probably have a few. Here are the ones we hear most - and if yours isn't here, our team is always happy to help

The Boost Kit uses the same professional-grade ingredients dentists use - just at a safer concentration, so you get effective whitening without the harshness. What really sets it apart is Potassium Nitrate, a proven ingredient that actively calms and protects sensitive teeth while you whiten. You don't just get a brighter smile - you get there comfortably, without the zings and sensitivity that other kits can cause.

Smilie's whitening gel formula works on natural tooth enamel only - it won't change the colour of veneers, crowns, fillings, or any other dental work. The good news is it won't cause any damage to them either. Many people use the Boost Kit to whiten their surrounding natural teeth to better match their existing restorations.

Sensitivity is something we take seriously. Our whitening formula includes Potassium Nitrate specifically to calm the nerve response while you whiten, so it's suitable for most people with sensitive teeth. If you have a specific dental condition or concern, we always recommend checking with your dentist first.
