Frequently Asked Questions

You asked, we answered! We’ve put together some of the most commonly asked questions about our ultraLED^™ teeth whitening. If you can't find the answers you're looking for below, head over to the Smileflex Help Centre for even more information.

: Yes! The mouth tray is flexible and will fit all mouth sizes.
: Yes but keep in mind, artificial dental work will not whiten. They are colour matched at the time they are created and do not have pores. The colour of your dental work cannot be changed (unless it is replaced).
: All teeth whitening work by absorbing into pores on the tooth surface. The active whitening agent in our dental grade formula is Hydrogen Peroxide (H₂O₂), a naturally occurring compound which breaks down readily into water (H₂O) and a single oxygen molecule (O). This single oxygen molecule is a strong oxidising and disinfecting agent, and is what gives Hydrogen Peroxide such effective whitening properties.
: Teeth whitening is only achieved with either Hydrogen Peroxide (HP) or Carbamide Peroxide (CP). HP and CP produce the same results, however HP whitens 3x faster and requires 3x less strength to that of CP to achieve the same results. This is because of the time needed for the CP to break down into HP first.

While formulas such as PAP and PAP+, are merely a temporary teeth "lightening" effect by dehydrating teeth rather than whitening and removing tooth stains. In the dental industry we call this "rebound" and people using those products find once their dehydrated teeth return to health 3–4 weeks later, their original tooth stains reappear (as they were never removed).

With all factors considered, it's why Smileflex chooses Hydrogen Peroxide as its active whitening agent to achieve the best and longest lasting professional results.
: Yes! Our product has proven to be highly effective at removing stains from teeth including coffee, tea, wine, tobacco, tetracycline, and various other tooth stains.

Rob S.

Smileflex's LED kit was such an ease to use and I noticed my teeth were brighter within just a few days. Highly recommend this brand.

Nishu S.

My teeth have been pretty yellow for sometime now. I was excited to treat myself and give the smileflex led kit a go. For someone that has smoked their whole life I am stoked to have a far less embarrassing smile now!

Paru B.

My teeth are much whiter and have stayed white. Unlike some products I've used from other online brands where my teeth have appeared white for only a few hours before returning back to their original colour.

James G.

Fantastic results! The LED light really seems to enhance the whitening. I recently had a clean at the dentist and then did the LED treatments. My teeth look amazing now.

Elizabeth S.

Great product! The LED light makes a big difference with the speed and effectiveness of the whitening. This is definitely a kit I'll continue to use in the future when needed.

Kabui G.

I have no hesitations recommending this kit. It has done an excellent job at whitening my teeth and improving the appearance of my smile.

Alex T.

My smile looks so much brighter! I love the LED system of this kit.

Rania C.

My teeth are visibly whiter. The process was simple and pain free. I'm loving my results.

Hugo D.

This is a fantastic whitening product. My teeth are several shades whiter so I couldn't be happier

Paul M.

Very impressed with the whitening power of this kit.

Raquel S.

The LED mouth piece makes the whole process so much more comfort than what I've dealt with in the past. There's no annoying bulky battery hanging from my mouth so you barely know you're using it. My teeth are looking a hell of a lot better than before! I'm super impressed and would recommend this kit to anyone.

Nelson D.

Love the convenience of using this kit at home. My teeth are starting to shine whiter more and more. Can't wait to keep seeing the results as i use the kit for a few more days.

Analise W.

Perfect for my sensitive teeth as I had no issues at all. Great results and no pain! That's everything I was hoping for!

Dianne R.

So impressed with this LED whitening kit! I saw good results after just a few sessions. I was more than impressed by the end of my full treatment.

Radu O.

I am hapy with the colour of my teeth now.

Josephine G.

This kit has whitened my teeth without any tooth discomfort. It's a joy having a mouthpiece without a bulky battery pack hanging out my mouth. All round it's an impressive product.

Jono F.

The shipping was super efficient. I had my led kit in 2 days and its working great so far.

Matthew P.

I decided to skip the dentist and give this LED kit a try. It was way cheaper and I'm really satisfied with the results that I got.

Yolanda H.

I have several weddings coming up & this LED kit has got my smile sparkling! Ready for wedding season woohoo!

Rafaela l.

I would usually reframe from showing my teeth when smiling for photos and so on. I'm so pleased to say that the self conscious worry has now gone. Super happy with my results. I didn't realise how easy of a solution it would be.

Andi R.

I'm a poor uni student that drinks way too many cups of instant coffee! Thankfully the smileflex LED kit is inexpensive and has done a stellar job at getting rid of my horrible coffee stained teeth!

Aaron L.

So far so good. My teeth are noticeably whiter and sensitive free.

Eden M.

I'm a massive Smileflex fan having bought several night guards over the years. I added the LED kit to my last order and have been enjoying incredible results. Everything from Smileflex has been brilliant. The one thing that's really stood out to me is the quality and attention to detail with everything. I love what they are doing.

Danica R.

Thank you for bringing my smile back to life! I work in retail and I've received so many compliments from customers. I literally should be asking for a commission for how many people I have recommended the whitening kit to.!

Rocco C.

My partner has used the custom whitening kit from smileflex for a number of years now. Rarely needing to top up as it seems the gel really does remove stains and whiten your teeth. After contacting customer support and confirming the formula in both custom and led kits are the same I decided to get myself the LED kit and this seems to work just as well. I think the ease of use of the custom kit is greater with the trays specially crafted for your own teeth however the LED kit is a brilliant cheaper alternative and both my wife and I are both extremely happy with our results.

Kathy M.

I have my wedding coming up in November so I wanted to try this kit a little in advance just in case it didn't work. I've finished my treatment and I am actually astounded by the results! For the price I really wasn't expecting such great results. I'll be getting my soon to be hubby on to this kit as well before our big day!

Davy M.

This whitening kit is top tier

Remy G.

I couldn't recommend this whitening kit anymore highly! The kit is easy to use and my teeth are noticeably whiter after the specified treatment time. I love how fast it works. Plus, the customer service was exceptional answering a few questions I had. I'm very happy with my purchase.

Gail H.

I've found this whitening kit to be very effective. Delivery was quick, the packaging is beautiful and now so are my teeth! My only regret is not buying this sooner.

Akari Y.

I haven't got a bad word to say about smileflex. I've gotten retainers and night guards through them over the years and every little detail has been spot on. Same with their led kit. My teeth are sparkling brighter than ever. So so pleased.

Stephanie S.

I'm someone that has struggled self-consciously for so long and one reason being was my teeth being so discoloured from many years of neglect. I tried a purple gel from another online brand that's advertised like crazy on social media which looked amazing when applied however as soon as I washed my mouth out with water to discard the excess gel, my teeth just looked back to their original stained colour. I came across Smileflex through social media as well, so I was a little wary to spend more money with the worry of it being wasted again. To my pleasant surprise though, the results have been nothing less than astonishing. I did wait a number of weeks before writing this review as I wanted to make sure the results weren't temporary. It's been a good 4 weeks since I finished the treatment process and results are still looking wonderful. (with tears in my eyes) Thank you so much!!!

Anna J.

The whitening kit is fabulous. My teeth are noticeably whiter after the two weeks. I'll be stoked if the results last for a long time like they claim.

Mimi C.

Definitely Recommend this kit. It has been effective at whitening my teeth and it was easy to use.

Chris F.

Best whitening kit I've used. It's so much better than having the annoying disc shaped battery pack hanging out of my mouth like all the other brands have. Has an inbuilt timer as well so you know when to finish each treatment.

Leah J.

I've always been skeptical about these LED whitening kits however after reading through the detailed information on the smileflex website I felt comfortable giving this kit a go while it was on sale. And wow! Worth every penny! It's simple to use and has delivered outstanding results.

Jamie M.

Highly recommend. Easy connection to my phone. 25 minutes goes pretty quickly when getting lost on TikTok

Maddison P.

I was skeptical but this teeth whitening kit exceeded my expectations. The results are stunning and with plenty of whitening gel left over ill be able to continue topping up for some time now. Good value.

Janelle O.

My girlfriend has the custom kit from smileflex and loves her results so thought I'd give the LED kit a go while it was on sale. The pen is easy to apply and it's working great so far! 2 happy smiling gals! x

Joan C.

Ordered over the weekend. Arrived on the Tuesday. Started whitening that night. Results by the weekend already impressive!

Katy S.

I drink 4+ cups of coffee a day so this whitening kit was much needed! I'm thrilled to find a product that works and is affordable. I also picked up a few extra pens while they were on sale as I know I'll be needing them further down the track with my coffee addiction

Em G.

Love this kit. Not needing to charge the device is a win!

Mel N.

Packaging is so cute! I've used the LED device for a week now. Loving the convenience and results so far

Lyle B.

I've been using the LED whitening kit for just over a week and I'm very impressed. It's so easy to use with power straight from my phone. I've already noticed a significant improvement in the colour of my teeth. Plus the process is pain free unlike other whitening methods I've tried in the past.

Chelsea W.

Fantastic! Simple to use and definitely works well. Highly recommend!

Yvonne C.

I think I got my first compliment from my husband in 10 years!

Taylah F.

Really happy with the results from using the LED kit over the past week. Its easier to use than I expected, and unlike other whitening products I've tried before it didn't cause any discomfort. Plus, the delivery was super quick!

Amelia W.

Couldn't be happier My new go to for teeth whitening.

Sian T.

Such an easy kit to use and fantastic results already after only 4 days!
