How long will it take to see results?

You’ll see a noticeable difference in the colour of your teeth after the first application. For best results, we recommend repeating the treatment over 6 consecutive days and up to 14 days to achieve the ultimate whitening result. Note, results may vary between individuals, depending on the type of stains on the teeth and the structure of the teeth. If you have any questions, please contact our team

Will using Smilie’s teeth whitening formula cause sensitivity?

The 6 per cent hydrogen peroxide formula is a gel which also contains desensitisers and soothers. This means it reduces sensitivity and works to strengthen enamel – as well as leaving teeth bright and white, making it ideal for those who have sensitive teeth yet still want professional results.

Can Smilie be used with veneers, caps, implants, bridges, or bonded teeth?

Smilie is safe to be used with veneers, caps, implants, bonding or bridges. However, as our whitening formula works to oxidise stains from natural teeth it will not whiten your restorations. You may find using Smilie helpful at keeping your surrounding natural teeth the same shade as the ones that have had dental work. If you have any concerns, please reach out to our team

How do I care for my Smilie LED Device?

To keep the mouthguard clean, rinse in warm water and air dry. Note, the device is 100% waterproof.

Can I use Smilie if i have a fixed retainer?

Yes, our whitening process should not interfere with this at all. The bonded retainer should not cause a problem as the whitening is performed on the front side of the tooth and won’t have any impact on the retainer or the glue.

Are Smilie’s products vegan and cruelty-free?

All Smilie products are 100% vegan and cruelty-free.

Is it safe to whiten my teeth if pregnant or breastfeeding?

We advise that pregnant women wait until after delivery and breastfeeding before starting teeth whitening. We always recommend consulting with your doctor or midwife prior to using Smilie products regarding any health concerns you may have.

There are so many teeth-whitening kits on the market, what makes Smilie the best?

We're happy you asked! With so many teeth whitening options on the market, it can be difficult to determine which ones deliver the safest and most effective results. Smilie is an Australian-owned business, backed by Doctor Daniel Tankard (member of the Australian Dental Association), who has over 15 years experience in the dental industry. Smilie is the combination of research and testing to ensure we can deliver the very latest and advanced in at-home teeth whitening technology.

How does the teeth whitening process work?

Tooth enamel is porous which allows it to pick up stains over time. Hydrogen peroxide, the active ingredient in our Smilie gel sets off an oxidation (chemical) reaction which releases free oxygen radicals. These free radicals attach to the discoloured organic molecules in your teeth to produce smaller stained molecules which have a whitening effect on your teeth. The Smilie LED light device does not whiten your teeth but speeds up the whitening process by activating the hydrogen peroxide in the Smilie whitening gel. This process is extremely safe and effective.

Is the device waterproof?

Yes, the LED device is waterproof so you can feel confident using it in the shower!
