HiSmile Teeth Whitening Review


What is HiSmile Teeth Whitening Kit?

Tooth discoloration is the most common problem of all dental issues. The causes of tooth discoloration include poor dental hygiene, tobacco use, disease, medications, genetics, aging, trauma, environment, and lifestyle factors like smoking and drinking beverages like coffee, wines, and tea, etc. Because of such diverse reasons, almost all of us may likely develop tooth discoloration to an extent. After developing tooth discoloration, we grew increasingly sensitive to our smile. To get rid of this unnecessary sensitivity, we must seek professional help for getting back our bright smile. But professional help is very costly- it costs you around 200 to 300 pounds in the UK!

HiSmile teeth whitening kit is a cheaper alternative to costly professional teeth whitening treatment- you can save up to 60% with HiSmile teeth whitening kit. HiSmile teeth whitening kit is an at-home teeth whitening solution designed to wash out stains and give you whiter and brighter teeth without any pain. The kit consists of a fixed-shape mouth tray, blue light LED device with a timer, 3 x 3ml syringes of whitening gel, user’s instructions, and a color chart to match the shade of your teeth and to measure your whitening progress.

Who Needs It?

HiSmile teeth whitening kit is suitable for every age group but you must have not any profound dental problem. In case, you are suffering from a major dental disease, you must consult your dentist before starting this at-home whitening treatment. HiSmile teeth whitening kit can treat any tooth discoloration. It is helpful in whitening

  • Yellow teeth due to loss of enamel layer
  • Brown teeth due to the use of tobacco and dark beverages like tea or coffee
  • Purple teeth due to consumption of beverages like red wine
  • Black teeth due to tooth decay

How Does It Work?

If you have any of the above tooth discolorations then go get your HiSmile whitening kit. HiSmile is a blue-light LED device that has small LEDs evenly distributing light across your teeth. When you get your package, open it, and follow the following simple steps to start your at-home whitening treatment.

  • First of all, unbox your package and fill the fixed-shape tray with the provided whitening solution (3 X 3ml syringes).
  • Then wear the mouth tray and power on the LED light. The LED light has an in-built timer of ten minutes.
  • Keep wearing it till the LED light is off (for ten minutes a day). When the light gets off, then remove the mouth tray.
  • Repeat the process for six consecutive days and feel the difference with the provided shade chart.

HiSmile claims that after wearing the mouth tray just for only one time, you will feel a considerable whitening effect. When you wear the mouth tray and power on the LED light, the whitening solution in the tray is activated and it starts its bleaching action and breaks away the stain molecules of your teeth.

In contrast to other whitening solutions that contain hydrogen peroxide as a whitening agent, the HiSmile whitening solution contains Phthalimidoperoxycaproic Acid (PAP) and Potassium Nitrate Hydroxyapatite as whitening agents. PAP whitens teeth through the process of oxidation which enhances the efficacy of the treatment. In addition to whitening teeth, Potassium Nitrate Hydroxyapatite mineralizes and strengthens teeth and protects teeth and gums from sensitivity.   

What is the Cost of the Treatment?

The HiSmile teeth whitening kit is a cheap, affordable, and effective at-home whitening treatment. The whole kit will cost you around 55 pounds. You can get whitening solution refills for just 20 pounds.

HiSmile offers a monthly subscription service that sets you up with monthly deliveries of your Hi Smile essentials, shipped to you automatically every month. With the subscription service, you will get a 15% discount.

  • Fast Treatment: This at-home whitening treatment spans over only 6 days and also the daily treatment process lasts only for ten minutes.
  • Cheap Solution: The HiSmile kit is not only quick but it is also cheaper. For example, the average cost of professional whitening treatment ranges from 200 to 300 pounds while the cost of the kit is only 55 pounds.

The unique and improved whitening solution formula of this kit not only whitens your teeth quickly but it also promotes teeth and gums’ health.

Likewise any other product, the HiSmile teeth whitening kit also has some downsides. The major downside of the HiSmile whitening kit is that this at-home kit is not as effective as a professional whitening treatment. This is quite understandable as the whitening solutions administered by a professional dentist contain higher concentrations of the whitening agent as compared to over-the-counter whitening products like the HiSmile kit. Also, at-home whitening treatment is slow-paced. For instance, you can whiten your teeth professionally in just one office visit but with the HiSmile teeth whitening kit, you have to wait for six days to get back your glittering smile.

HiSmile teeth whitening kit is one of the best at-home teeth whitening solutions. This is the reason why people are increasingly using it and are satisfied with its treatment. On the trust pilot, HiSmile has a 4.5 rating. Following are a few of the patient testimonials praising the effectiveness, reliability, and safety of the HiSmile kit.

“It is easy to use and has a simple step-to-step guide. I was sceptical too it as always with these kinds of commercialized products, but it is easy to use and has a simple step-to-step guide. Clean package and everything; already seeing results after 4 uses.”


“Absolutely amazing love this product I could see my teeth getting whiter every day love it.”

Bryce Barley

“Very good product. After using it for 2 days I already noticed a my teeth was looking better, after the 6 days of use my teeth was a lighter shade. Definitely a 5 star product, will be buying the gels to continue the whitening effect.”

Dan Mason

“Can really see a difference within 3 uses, my teeth are definitely whiter, I don’t smoke or drink any dark drinks so this helps too. Have ordered refills. Can’t wait to see the end result. Only thing I would say is that it would be better to have a mouldable gum shield to use. I would suggest applying the gel directly onto the teeth.”

Sacha Williams

“I have only had the product for a day now, so it is far to early to determine whether or not I feel this is a legitimate and effective whitening plan.. which is why I stuck with a 4 star rating for now. Ordering was easy, its not overly pricey, and it all arrived rather quickly. If it does end up working well, this product/company is an easy 5 Star rating for me personally.”
