About HiSmile

By HighYa Research Team
Updated on: Mar 28, 2018

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, the company 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 eight shades whiter within six applications.

Add to this HiSmile’s 100 percent 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. First, we’ll talk about the price of their different products.

HiSmile Products, Pricing, and Refund Policy

Overall, HiSmile currently offers five different natural, vegan products, which come with a 30-day money-back guarantee (from the date of purchase), if customers don’t achieve teeth that are at least two shades whiter.

According to the company, here’s what you’ll have to do to request one:

  1. Take a clear photo of your teeth before using.
  2. Use exactly as instructed.
  3. Take a clear photo after you've completed all whitening applications.
  4. Send your before and after photos to the company, along with a photo of the used products.
  5. Once approved, your refund will be processed.

Peroxide Free Teeth Whitening Kit

HiSmile’s kit includes 3 x Teeth Whitening Gel syringes, 1 x Mouth Tray and LED Light, a Teeth Whitening Shade Guide, and a step-by-step Instruction Manual. Here’s how it works:

  1. Apply 1/4 of the gel to the face of the top of the mouthguard, and 1/4 of the gel to the face of the bottom of the mouth guard.
  2. Then, place the guard in your mouth and turn the LED light on. After 10 minutes, the light will turn itself off and beep.
  3. Afterward, rinse your mouth and mouthguard.

The kit will give you six applications (two applications per syringe). The company recommends using the gel every day (consecutively) for the first six applications, followed by one weekly application to maintain results.

HiSmile’s Whitening Kit is priced at $79.99 AUD, $59.99 USD, £49.99, €54.99.

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

Day & Night Toothpaste

The Day formula contains something called a Micro-Shield wax that promises to prevent stains from occurring, while the night toothpaste is said to use “charcoal and other natural ingredients to remove stains and detoxify the mouth.” Features a pleasant peppermint flavor.

Pricing: $19.99 AUD, $15.99 USD, £11.99, €13.99 (available on subscription for 30 percent off).

Teeth Whitening Gel Syringes

These use a blend of sodium bicarbonate and sodium chlorite to provide whitening, along with light activators like pomegranate, aloe vera, and chamomile, to help whiten up to eight shades in 10 minutes, without sensitivity. For use with HiSmile’s LED Light & Mouth Tray.

Three gel pens are priced at $29.99 AUD, $23.99 USD, £18.99, €21.99 (available on subscription for 30 percent off).

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 $29.99 AUD, $23.99 USD, £18.99, €21.99 (available on subscription for 30 percent off).

Coconut Whitening Mouthwash

Features sodium bicarbonate as its key whitening ingredient, along with coconut to extract toxins from your teeth and gums. Application only takes about two minutes.

Five coconut tubes and an instruction manual will cost you $29.99 AUD, $23.99 USD, £18.99, €21.99 (available on subscription for 30 percent off).

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, 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 as $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.

The sodium bicarbonate (more commonly known as baking soda) in products like HiSmile, 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.

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-based 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.

What are HiSmile’s customers saying about their results?

A Look at HiSmile Customer Reviews

Since writing our original article, more than 80 HighYa readers provided their feedback about HiSmile, giving the company an average rating of 3.3 stars. Common compliments referenced ease of use, effective results, and solid customer support, while complaints often related to no results. In most instances, a company representative responded directly to this feedback.

TheBlondePerfectionist.com noted that HiSmile was "incredibly easy" to use and that they experienced results by the second application. Ultimately, they were "blown away" by 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 of professional whitening treatments in the past, as well as numerous at-home treatments, and concluded that her teeth simply couldn't get any whiter.

The Bottom Line: 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 potentially achieve similar results using a DIY baking soda paste, which can be made for just a couple of 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.

  • This does not work

    I followed each step carefully and was sent a guide on how to use it by the company themselves. This did not work and in fact, made my teeth look more yellow than before. I thought this would work. I applied everything correctly and used this at night after brushing my teeth. I avoided bad foods yet despite this, it did not help.

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

    Just reading these reviews are scary! It’s bad for your enamel and you shouldn’t keep using or lose all of your enamel? I had some sensitivity after the 3rd use and they did not appear any whiter after the 6th use. I regret purchasing this product and I’m waiting for a reply back from them and I’ll post there response!

    It is not working at all! Stay away, it is a scam. No sensitivity - yes, but it's is not whitening your teeth. Total waste of money and time!

    Stay away, stay away, stay away.

  • Doesn't work. Bad customer service.

    I bought this with good expectations but after a full use of its six days, my teeth looked exactly the same. After each use, I did not notice even a slight change, which was disappointing.

    I emailed customer service dept about two weeks ago explaining my dissatisfaction and I never heard back from them even though there is supposed to be money back guaranteed.

    A certain scam and please don't be fooled. It doesnt work.

  • No result

    • By Lisa S.,

    • Verified Reviewer

    The videos and reviews show that it makes your teeth shade lighter, and after multiple uses as directed, with the day and night toothpaste, I did not notice any difference at all.

    Crest white strips did way more for me than this.

    Do not recommend - advertisements seem skewed.

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

  • Not impressed

    • By Lily B.,
    • Brisbane, Australia,

    • Verified Reviewer

    I ordered this after seeing all the ads that made it seem that HiSmile seriously whitened your teeth. When I ordered a while back, they claimed it would whiten my teeth by 8 shades. Today, I went back and their claim has gone down to 2 shades. I’ve ordered twice in hopes that my teeth would reach the maximum white they could. However, after two purchases (12 sessions) my teeth are maybe 1 shade lighter (if I’m really pushing it). Not impressed. I am going to head to the dentist from now on. I blew 120 bucks on the stupid thing.

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

      Each individuals lifestyle choices may inhibit the overall outcome of the whitening process, and we recommend limiting the intake of staining food and drinks to assist in optimal results.

      We look forward to speaking soon.

    An amazing experience! My teeth got whiter in just six days! I loved it and the results are really fast and safe. I really recommend this product to everyone that wants whiter teeth fast. The product is so simple to use, and the directions are very clear. You can really see a difference from the first use! I loved it!

  • A clear difference

    I have very sensitive teeth so using Crest Whitestrips never went well for me, but after using HiSmile, I realize I never need those strips again. My teeth were clearly brighter just after two applications, and I started receiving compliments from everyone and many people asking what product I am using. I will be purchasing more syringes soon!

    I have been using HiSmile for 5 and 1/2 days now. I have compared my teeth from the chart (5) until now and there is absolutely no difference. I feel as though this has been somewhat of a scam and it’s rather upsetting.

    HiSmile has done literally nothing. ,I’m on day 6 today and there has actually been no difference whatsoever.

    This whitened better than my dentist could. I had no problems with HiSmile. I saw major improvements after the first use. I just finished my 6th day, and WOW, it really works, thanks HiSmile.

    Living with depression, I let myself go, gained weight, got yellow teeth, and quit exercising, but this just gave me a boost of morale to change things around.
