Safe for Sensitive Teeth

Smilie's formula contains Potassium Nitrate - a clinically proven ingredient that calms and protects sensitive teeth during whitening. If other kits have caused pain or discomfort in the past, Smilie is specifically formulated to change that.

We understand at-home teeth whitening can be scary for those with sensitivity, that’s why we’ve developed a formula containing desensitisers and soothers designed specifically to whiten, without the pain. The Smilie formula contains the following Ingredients: Propylene Glycol, Glycerol, Water, Hydrogen Peroxide (6%), Carbomer, Carboxymethylcellulose Sodium, Polyvinylpyrrolidone, Menthol, Sodium Hydroxide.

We're so confident you'll love your results that we back every order with a full 30-day money-back guarantee. Not happy? We'll refund you completely - it's that simple.

1. Brush your teeth, then apply the Smilie formula evenly to top and bottom teeth
2. Place the mouthpiece gently in your mouth and whiten for just 16–30 minutes
3. Rinse your mouth and the mouthpiece to reveal a brighter, whiter smile

Frequency: Each kit contains 30 treatments. Use once daily for 16–30 minutes until you achieve your desired shade. For long-lasting results, maintain with one treatment every two weeks.

Press the button until the light turns on and place the device comfortably in your mouth.

Step 3

FAQs

Start by charging your LED device for one hour before your first use. Brush and dry your teeth, then apply the whitening gel to the front of your top and bottom teeth using the precision brush. Apply an even, generous layer by brushing from the top of each tooth downwards.

Next, place the mouthpiece in your mouth and gently close your lips around the device. Press the button to switch it on and whiten for 16–30 minutes. When finished, remove the mouthpiece, spit out any excess saliva, and rinse your mouth with water. Rinse the device with water (or gentle hand soap for a deeper clean), dry, and place back into the holder for storage.

For best results, use once daily for 7 days. After your initial treatment, maintain your smile with a quick touch-up every two weeks or as needed.

The Smilie Boost Whitening Kit is designed with the same professional-grade ingredients dentists use, but at a lower and safer concentration - so you get effective whitening without harshness. What truly sets it apart is the added Potassium Nitrate, a proven ingredient that helps calm and protect sensitive teeth while you whiten. This means you don’t just get a brighter smile - you get it comfortably, without the pain that many other whitening kits can cause.

Use your Smilie kit once a day for 16–30 minutes over a period of 7–21 days, depending on your whitening goals. If you experience sensitivity, simply pause for 1–3 days and then continue your treatments

While every smile is unique, Smilie products are formulated with sensitivity in mind. The majority of our customers whiten comfortably without experiencing sensitivity
