About HiSmile

You want a whiter smile, but your teeth and gums are too sensitive for hydrogen peroxide.

The good news is that HiSmile manufactures a line of peroxide-free teeth whitening products that use sodium bicarbonate instead, which can provide a pain-free alternative. No more irritation to your gums or mouth.

Despite its gentleness, HiSmile claims their teeth whitening systems can deliver noticeable results in as little as 10 minutes by removing extrinsic (i.e. surface) stains, and can make your teeth up to 6 shades whiter within 6 applications.

Add to this HiSmile’s 100% clinically proven results and patented mouth guard, and you’ve got a safe, easy, and effective way to whiten your teeth in the comfort of your own home.

But before you hand over any money, there are some things you need to know about HiSmile. First, we’ll talk about the price of their different products.

HiSmile Products, Pricing, & Refund Policy

Overall, HiSmile offers 4 different products:

Peroxide Free Teeth Whitening Kit

HiSmile’s Teeth Whitening Kit contains everything you’ll need to start whitening your smile. This includes:

  • 3 whitening gel syringes
  • 1 LED light
  • 1 mouth guard
  • 1 teeth whitening shade guide
  • 1 step-by-step instruction manual

With the gel already loaded, all you need to do is dispense ¼ of a syringe into each side of the mouth tray (enough to coat your teeth, but not your gums). Then, insert the tray into the LED light, place the tray in your mouth, and keep it in place for 10 minutes (the light will turn off once this occurs).

With this kit, you’ll have 6-9 applications available.

HiSmile’s Whitening Kit is priced at $79.99 AUD (about $57 USD).

If you’ve ordered HiSmile’s Whitening Kit previously and only need individual pieces, these are available for purchase as well:

Peroxide Free Teeth Whitening Gels

This includes 3 syringes pre-filled with peroxide-free whitening gel (enough for 6-9 applications).

A one-time purchase is priced at $39.99 AUD (about $29 USD), or you can subscribe for monthly recurring shipments, which will drop your price to $25.99 AUD ($19 USD) per month.

Peroxide Free Teeth Whitening Pen

HiSmile’s Teeth Whitening Pen can be used for touch-ups when you’re on the go, and is also great for hard-to-reach areas. Contains the same peroxide-free formula found in the syringes.

Priced at $34.99 AUD (about $25 USD).

LED Light & Mouth Guard

HiSmile's patented LED Light and Mouth Guard combo contains the strongest LED light on the market, along with a double-sided mouth guard to prevent spillover. The mouth guard is reusable, and batteries are included.

Priced at $59.99 AUD (about $43 USD).

How Do HiSmile’s Prices Compare To Other At-Home Whitening Kits?

Compared to some of the other teeth whitening products we’ve reviewed here at HighYa, including Whitening Coach, Action Pro White, and many others, HiSmile’s kit is about half the price.

However, the ASOTV whitening kit Dial-a-Smile comes in less than HiSmile, while other tray-based bleaching systems can be purchased locally for as little at $11.

Granted, all of these use hydrogen peroxide, while HiSmile uses sodium bicarbonate. But whether we’re talking about tooth sensitivity or whitening results, is there any difference between these two ingredients?

Hydrogen Peroxide vs. Sodium Bicarbonate

Most at-home teeth whitening kits use carbamide peroxide, which breaks down into hydrogen peroxide. In turn, this creates an oxidation reaction that dissolves stains and lifts them away.

Sodium bicarbonate (more commonly known as baking soda), on the other hand, basically acts as a mild abrasive to scrub away stains from the surface of your teeth.

Comparing their effectiveness, carbamide/hydrogen peroxide is generally more effective at removing stains, especially those that may be older and located deeper within your teeth. However, it can cause some tooth and gum sensitivity, although this usually subsides quickly after treatment.

Overall, after undergoing exhaustive clinical testing, peroxide is considered very safe by the ADA for use in at-home whitening products. In general, it does not cause “un-repairable damage to tooth enamel” or receding gums, as claimed by HiSmile.

Interestingly, since it’s an abrasive (however mild), extended use of sodium bicarbonate can lead to irreparable enamel damage. Sure, you might not experience any immediate tooth or gum sensitivity, but over the long term, using a baking soda-bases whitening system can be much more harmful to your teeth than a peroxide-based one.

In all, this means that peroxide-based whitening systems will likely provide you with better, safer whitening results than ones like HiSmile—if you don’t suffer from tooth or gum sensitivity.

But that’s our take. What are HiSmile’s customers saying about their results?

Customers Aren’t Speaking Out About HiSmile

Considering the company’s popularity and very active Instagram page (including dozens of endorsements and before and after pictures), there wasn’t a whole lot of HiSmile feedback at the time of our research—and nothing outside of independent blogs (the company is Australian, and isn’t listed with the BBB).

TheBlondePerfectionist.com noted that HiSmile was “incredibly easy” to use and that they experienced results by the second application. Ultimately, they were “blown away” with how effective it was.

Similarly, InsincerelyHer.com noted that HiSmile worked fast and gave them “super white” teeth in weeks.

PetiteAnchors didn’t see much of a difference with HiSmile, and claimed that “it made no actual difference to my teeth colouring.” Granted, the author noted that she had undergone a couple professional whitening treatments in the past, as well as numerous at-home treatments, and concluded that her teeth simply couldn’t get any whiter.

Now, let’s wrap everything up as neatly as the box HiSmile comes in.

Is HiSmile a Pain-Free Way To Whiten Your Teeth?

Can HiSmile provide you with a whiter smile, without sensitivity? With its baking soda-based whitening gel, it’s certainly possible.

Will it provide you with similar (or better) results than other peroxide-based at-home whitening kits? Again, it’s possible, although hydrogen peroxide is generally more effective at removing stains underneath your enamel, which could provide more shades of whitening.

Will HiSmile’s LED light provide any better or faster whitening results? Almost certainly not.

Given all of this, will HiSmile provide a solid value for the money? If tooth and gum sensitivity is your number one concern (and you’ve already tried a peroxide-based kit), then baking soda-based products might be your only option.

The catch here is that you could reasonably achieve similar results using a DIY baking soda paste, which can be made for just a couple dollars. Or, you can purchase a tube of baking soda toothpaste from several different national companies for not much more.

Despite these concerns, the before and after pictures features on HiSmile’s Instagram page indicate that the company has hundreds of satisfied customers. Although due to the abrasive nature of the baking soda in HiSmile’s gel, we’re hoping they don’t continue using the product for too long, or they might permanently damage their enamel.

  • Best whitening product

    This is the only whitening product I've ever used that hasn't made my teeth hurt afterward, and it has given me noticeable results. I'm more than impressed with HiSmile and the confidence it has given me.

  • Fast postage and great product!

    I'm absolutely thrilled with the customer service I received and how quickly I received my items! Owning an online business myself, I know how busy this time of the year is, not to mention postage times. I ordered from HiSmile on Wednesday and received my package today (Friday).

    I'm in disbelief of how quickly it arrived!

    I've just had my first teeth whitening session and can already notice results! I can't wait to continue with the application and see what a difference it makes for my smile.

    Thanks so much guys, one super happy customer right here! ❤️

    Bottom Line: Yes, I would recommend this to a friend

  • Not happy yet.

    • Indiana,
    • Jan 14, 2017

    I just, and I do mean JUST, completed my first 10 minutes of HiSmile teeth whitening. I took before and after photos as well, and I shared them on Instagram.

    I see videos everywhere of people doing their first before and after, and they get 1-2 shades lighter their first time.

    I do know everyone's teeth are different. My teeth are sensitive, and I was between a 3 and 4 on their color scale that comes in the kit. After doing my first time, I was not in pain, which was AWESOME for someone with sensitive teeth.

    BUT, my teeth afterward not only did not move shades (they claim it'll do a shade a usage in their "6 shades in 6 days") but now my teeth also have SPLOTCHES of whiter color, and they look horrible! I'm willing to give it time, but I'm not happy yet.

    I was given this kit for Christmas and hope my mom didn't waste money on this kit for me (if it doesn't work).

    Bottom Line: No, I would not recommend this to a friend

  • Amazing

    This product is amazingly true, definitely not fake. I've been using this product for a while, as well as the teeth whitening pen. It is great, and I have been suggesting this product to all my family and friends, and I do so to whoever is reading this. Thanks HiSmile, I'm much, much more confident with my smile.

  • Gentle and easy to use

    • Sydney, Australia,
    • Jan 12, 2017

    I have very sensitive teeth, but this didn't irritate my gums at all. It gently whitened them, so don't expect drastic results overnight, but the use of it every day really did get rid of some of those horrible dark stains! I'll definitely keep using their products.

    Best experience

    I drink a lot of coffee so my teeth needed something really good but not something to make my teeth sensitive. I heard about HiSmile and beside the fact that I don't have sensitive teeth, I love how my teeth got white again! I highly recommend HiSmile.

    Love my new smile

    I've always been afraid to smile due to yellow staining on my teeth and thought there's nothing to lose, may as well give HiSmile a go.

    I bought my HiSmile kit with an easy process online and speedy delivery! After I had completed my six days of teeth whitening with the LED light and mouth guard, I went from a "5" to a "3" on the guide that came with the kit.

    I am no longer afraid to smile and show off my pearly whites. I highly recommend it, and have already told everyone I know!

    Fantastic results

    HiSmile is such an amazing product and a good price, compared to how much you pay the dentist. I absolutely love that it doesn't effect your enamel, which makes it such a perfect part of your daily routine.

    I'm absolutely in love with it, thank you!
