That’s essentially HiSmile. It’s a whitening system that’s been advertised like crazy all over the internet and with the “help” of these celebrities, it’s no wonder it’s taken the world by storm! And of course, being the curious dentist that I am, I wanted to see what this is all about! I also can’t recommend it from a professional point of view because I can’t verify the ingredients. Apart from them listing the ingredients, we have no idea about where they sourced or where it’s manufactured. As previously mentioned, they also don’t state the concentration of the “key ingredients”.

The kit is supplied with a shade guide but it doesn’t actually represent reality. I’ve never seen red teeth in my life. Nor in my almost ten years as a dentist! Have you?

But because of all of the hype for this product, I thought I’d put it to the test in my HiSmile review!

Many people that are looking to brighten up their smile wonder, “Is teeth whitening safe?”. No one wants to damage their tooth enamel when they’re just trying to look their best. Dental restorations may be safely treated with all Hismile products. Veneers, crowns, fillings, bridges, bonds, and implants fall under this category. But bear in mind that, unlike your natural teeth, restorations cannot be color-corrected. Essentially, the ingredients that are in the HiSmile gel have little, to no whitening effect if you understand what these chemicals are and how they work. The concentration of each active ingredient, how the chemical needs to be formulated and the stability of the entire formulation all affect how well teeth whitening agents will work. Another key ingredient in HiSmile is hydroxyapatite – also known as calcium phosphate – which is the main component of tooth enamel. While not widely available, it's found in some toothpastes to help strengthen teeth.

According to the American Dental Association, sensitivity will appear within a few days of starting treatment. I saw results after two treatments. Results vary depending on your level of tooth discoloration.Hismile’s whitening kit comes with six refills (enough for six full treatments). GLO Science products do not cause sensitivity in the majority of customers. Even if you experience sensitivity, it will likely be very mild and temporary.Each treatment session takes 32 minutes (8-minute intervals). Keep in mind that this product does not actually erase stains — instead, it brightens the look of yellow teeth temporarily. For this reason, Hismile recommends combining the V34 Color Corrector with their PAP+ teeth whitening system for best results. FAQ How long does V34 Colour Corrector Last?Those two were much more delicious tasting. Then again, I’ve yet to encounter a teeth whitening product that tastes like food! Teeth whitening strips, toothpaste, and products like HiSmile owe their popularity to a discovery made by dentists that ended up launching a new cosmetic dentistry market in the late 1980s. Personally, I’ve been using it about once every three weeks, usually in line with a special occasion. You could absolutely use it more often without causing damage, but keep in mind you’ll go through the pods faster, so best to find a sweet spot that works with your budget. For daily maintenance, the brand offers a PAP+ toothpaste and mouthwash as well.

I think it’s really neat that the whitening pen can still be stored in an upright vertical position. Although it is meant to be carried with you on the go if you wanted it to be. The ideal time to use the V34 Color Corrector serum is after bleaching. Hismile advises taking it after a complete PAP+ whitening procedure to get even better results.
