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.

    The peroxide free teeth whitening kit worked a treat! I noticed an amazing difference after only my 3rd application and have been using HiSmile daily. My absolute biggest love for HiSmile is because of the fact that I have experienced no pain or sensitivity issues at all. I've had a smile on my face for the past few weeks and am so happy with my purchase, will definitely continue using HiSmile!

    I decided to purchase the peroxide free whitening pen through HiSmile. After testing many products I was eager to try a product from their peroxide free range. The pen definitely lived up to my expectation, and was so easy to use. I was also extremely surprised, and impressed, by their fast delivery time and excellent customer service.

    All in all, I was happy with the product and the overall experience.

  • Excellent Customer Service

    I recently purchased a teeth whitening kit and gels from HiSmile. I was unaware of customs charges when ordering and was met with these when the product arrived, I couldn't pay the pricey charges so had to turn away the product. On emailing HiSmile they were extremely apologetic (even though it was my fault for not checking on the website about charges) and I was offered a refund straight away. I was amazed by how friendly and helpful the customer service team were and I have never been given a more hassle free refund. Overall amazing service.

    Hi there.

    First off, a big shout out to HiSmile and it's out of this world products! I have been using HiSmile products for a few weeks now, and am completely addicted and in love with how white my teeth now are.

    Despite some of these bad reviews, give HiSmile a go because it does vary from person to person, and the state your teeth are already in. But I am definitely satisfied!

    Thanks HiSmile, and to future HiSmilers, happy HiSmiling.

    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!
