HiSmile Reviews


HiSmile is a teeth-whitening company that claims it uses sodium bicarbonate as an alternative for hydrogen peroxide that will keep your teeth white all day long. It is perfect for people with gums and teeth that are sensitive to hydrogen peroxide, making HiSmile a discomfort-free alternative.

The company claims that the product will make your teeth 8 times whiter in less than ten minutes. It acts by removing surface stains. With the mouth guard which is patented and positively proven clinical results, HiSmile products offer you to the comfort of safely and effectively whitening your teeth without venturing out of your home.

The promotion of this company has been fueled by the modern use of social media and celebrity endorsements.

How does HiSmile works?

According to the company, HiSmile uses a whitening gel that has been formulated to clean your teeth stains while not damaging your tooth enamel.  The company offers five products, some of which comes with a return policy of 30 days. Primarily, the company sells a teeth whitening kit; each component of the box are sold separately as well.

Peroxide Free Kit for Teeth Whitening

Inside the kit, we will find a patented Rubber Mouth Tray and LED Light (1), syringes with gel for teeth whitening (3), instruction manual, and a shade guide. The whole kit is priced at $79.99 AUD ($56.40 US).

Combined with the use of the LED light breaking down the whitening agents of the effective formula, the whole procedure guarantees positive results within ten minutes; your teeth will be 8 times whiter with just six applications.


  1. First, apply about 1/4th of the whitening gel content on the mouth guard’s top face, and another 1/4th on the bottom face.
  2. Insert the guard into your mouth. Now turn on the switch for LED light. In ten minutes, the LED will switch off automatically.
  3. Rinse and wash your mouth. Make sure to clean the mouth guard.

The manufacturer recommends you to use the gel for six consecutive applications, after which you can use it weekly to maintain the results.

If you already have the kit and looking for single pieces, you can find them available for buying too:

  1. Day and Night Toothpaste

This toothpaste has two formulas with the day part featuring an effective Micro-Shield that protects your teeth from stains. The Night formula removes stains and detoxifies the mouth. It comes in a peppermint flavor as well.

  1. Gel Syringes for Teeth Whitening

This gel blends sodium chloride and sodium bicarbonate together with light activators such as aloe vera, pomegranate and also chamomile. This helps you whiten your teeth up to nearly eight times within 10 minutes. These gel pens are to be used exclusively with the mouth guard.

  1. Teeth Whitening Pen(Peroxide Free)

These whitening pens are for when you are on the move. They clean difficult to access spots. It also contains a similar formula that is free of peroxide as the syringes.

  1. Coconut Whitening Mouthwash

It contains sodium bicarbonate as the primary ingredient in addition to coconut. This mouthwash extracts the toxins present in your gums and teeth. It takes only about a couple of minutes to apply and rinse.

Once you have achieved the desired effect, the company states that you will need to use the product next somewhere between one-three months. The customers can maintain the results using the HiSmile Whitening Pen.

HiSmile Ingredients

According to many HiSmile reviews, most of the HiSmile products consist of five ingredients. The two whitening ingredients are sodium hydrochloride and sodium bicarbonate (or baking soda). The rest of the light activating ingredients are aloe vera, pomegranate, and chamomile. Baking soda is used as an agent in the formula because of its abrasive nature that cleans the stains from your teeth without disrupting your enamel.

Any HiSmile Side Effects?

Several HiSmile reviews state that using sodium bicarbonate extensively can cause enamel damage that can be irreparable. You may not experience such at the start, but over a long span of time, using sodium bicarbonate-based whitening gels are more harmful than gels based on peroxide.

Our Verdict on HiSmile You can opt for HiSmile products if your gums and teeth are sensitive to peroxide-based products. The sodium bicarbonate in HiSmile products has minimal diverse effects. Several HiSmile reviews state that in its gel form, the sodium bicarbonate won’t damage your teeth but will still remove stains like smoke tar and coffee.

But, you also need to keep in mind that prolongs usage of sodium bicarbonate products can lead to permanent damage to the gums. So, HiSmile products are recommended for people with sensitivity to peroxide-based products. But if you want a product that does not produce any sensitivity even on prolonged use, we strongly recommend the Active Wow Charcoal Whitening product. It has premium ingredients obtained from the purest sources and is very good for gum health.
