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.

  • No response and can't track

    • Faroe Island,

    I saw HiSmile's products everywhere and thought that I would try it out. Everyone got good results and everything so it should work.

    I purchased it on the 14th of this month and got an email saying that the packed was being shipped and I could track it with a link in the email. Only to be thrown back onto my final order side to see a box where it said: "Direct Link tracking number: N/A." And there is no way for me to track my order.

    I thought that maybe something was wrong and emailed HiSmile about my problem tracking my order. I got an email back saying they had gotten my email and would be in touch soon.

    It has now been four days, and nothing has happened. I emailed them again today hoping for a response.

    Does anyone know anything about this?

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

    Disgusting treatment of customers

    My delivery hadn't progressed for a week, so I emailed them. They told me I should call Australia Post. Australia Post tells me that HiSmile has only issued a manifest but didn't actually give them a physical parcel to send. So I email HiSmile asking them to follow up. They tell me to wait.

    So I wait. The delivery progressed as soon as I mentioned the issue to them. Then I email them asking for a resolution to my complaint, and why should I pay for delivery when they haven't delivered it on time, and I've had to spend time resolving their issue?

    They responded to tell me that I should visit nearby post offices to find my parcel. The delivery details clearly say it's in transit so why tell me to visit the post office? I have chronic health issues which make it difficult for me to leave the house and their treatment of me is plain cruel. They've not once offered to follow up on the whereabouts of my parcel or offered to treat me with any respect. It's one big cruel joke to them.

    I've paid for an item I haven't received, I've had to follow-up on the delivery that has never arrived, and they clearly get a rise out of torturing those with chronic health problems. Apparently, that's fun.

    I would be happy to share their email correspondence with the media. Not a good look.

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

    No refund as I haven't taken photos before treatment

    The treatment didn't work for me. I asked for a refund and it was denied as I have not taken pictures before starting the treatment. I am sorry, but I didn't know it was NOT going to work? They should mention it on the box or instructions. PLEASE BE AWARE before buying the product. I am very disappointed.

    Shipping fluke

    HiSmile seemed like a reputable company at first glance. Then, I ordered my package and was completely disappointed. I bought $9.99 shipping so it would arrive in 2-4 days, but they don't tell you it's on their terms. Still waiting for my package. I emailed and they told me to allow another 48 hours and they will not refund me for my shipping charge. That's not good, and I would not order from them again.

    Unsure

    • Aug 16, 2017
    • Verified Reviewer

    I bought the kit and I've used two gels within seven days by following instructions. I went to buy more, and they're $30 for a box of three. Pretty pricey when you think about it, considering the kit is $80, and if you were to buy the gels every week, that's like $170 a month. After one week I haven't seen any difference, plus I paid express and didn't get it within the promised two days, and they didn't reply until the day I received it saying "it's been delivered." Pretty unhappy.

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

      Hi Kellie,

      Thanks for sharing your feedback.

      As I am sure you can understand, that results may vary from person to person depending on the severity of the pre-existing stains and the individual's natural inability to whiten past a certain shade.

      If you wouldn't mind sending through an email to help@hismileteeth.com our customer care team will be more than happy to further assist you in regards to your parcel arriving after the timeframe.

      We look forward to hearing from you.

    Didn't work

    I bought this product for my friend and myself. It arrived late, then we tried it and it didn't work. I thought maybe I did it wrong, so I tried again. Again it didn't work. Avoid this product.

      I'm not sure if I would buy it again. I bought the kit which isn't cheap, it's $80. It arrived late after paying express postage. I've used the gels within six days by following the instructions. I went to buy the gels again and they're 3 for $30. I just don't know if it is worth it, plus I can't see a difference at all.

    Unfortunately, HiSmile did not work for me. After completely using the kit in six days, I did not see any difference in my teeth's color. Could be that my teeth are stained more permanently than most, as I've tried other whitening methods and saw limited results. HiSmile did offer me a refund, but I have to pay for $22 shipping so, not that happy.

    This is the third application, and there is no difference. Should I worry about that? So many people are saying they noticed the difference from the first use, but actually, I didn't.

    I'm worried about that.

    Teeth whiter than my legs!

    This is a great product, and I am very impressed. I had bought my sister one for her birthday, and it has done wonders. Even after the first go!

    I might treat myself to one for my upcoming birthday.

    What a great product!

    I have searched for a long time for a product that will whiten my teeth safely and fast. The solution? HISMILE! I got the teeth whitening kit from my sister (christmas present) and decided to buy it again and to the teeth whitening pen and it was such a great deal.

    First of all, the price is super cheap especially for the whitening pen (well for me)!

    Second of all, they really do whitening your teeth in such a short time, it is magic.

    Third of all, they don't make my teeth more sensitive and that is a big plus for me. In general, they are the best

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