Smartsmile Professional Teeth Whitening Kit Review: Everything you need to know


 I have always been curious to try out teeth whitening gels. I have only been using whitening strips so far like I explained in my review of  Crest 3D White Luxe Whitestrips Professional Effects
and I thought it was time I pick up something new. Teeth whitening is as delicate as it gets and one mistake could ruin your teeth and that includes using too much whitening products frequently.
So to avoid having to test many products, I braced myself to find the ultimate best teeth whitening gel so I wouldn't have to waste my money on something that doesn't work and therefore have to buy another product.

As it is my norm, I like doing intensive research before buying a whitening kit from Amazon or anywhere else. The research also helps greatly with my reviews because apart from my personal experience, I get to know what other people have experienced with the products and share the tips here.
So after some amount of research I found Smartsmile Professional Teeth Whitening Kit . It had really good reviews on Amazon and many people rated it 5 stars. In fact at the time of writing this review, the product had 532 reviews and more that a third of those gave it a five star. 
Most customers also admit that they start seeing changes after only the first treatment. I contacted a few friends of mine who have used this product and they confirmed that it was incredible. I didn't want to raise my hopes too high though. I had neglected whitening my teeth for a couple of months and the stains were beginning to build up again. Mind you, I cannot promise I stopped taking coffee. 
I ordered  Smartsmile Professional Teeth Whitening Kit and got it after 48 hours. 
I am going to show you how I used it and whether it worked for me or not. Read on.

The package


The kit contains the following stuff:
  • Two 2x 10ML whitening gel syringes for 20 treatments
  • LED light (Later versions do not come with this and you will have to order it separately. It is not a must but it helps speed up the whitening process)
  • Two whitening thermo-forming mouth trays
  • Two vitamin E swabs (May not be present in some kits)
  • Whitening-shade guide
  • Instruction booklet


I usually check for ingredients before using any whitening products. I want to make sure that the product has the essential whitening ingredients and non of which I am allergic to or will make my teeth too sensitive.
 Smartsmile Professional Teeth Whitening Kit gel has the following ingredients.
  • Propylene Glycol
  • Kosher Glycerine
  •  Carbamide Peroxide
  • Hydrogen Peroxide. 
Hydrogen peroxide and carbamide peroxide are important whitening ingredients and any teeth whitening product you buy must have either both or one of them.
 Smartsmile Professional Teeth Whitening Kit gel has 35% Carbamide peroxide which I was skeptical about because I sensed that much might make my teeth too sensitive, though I hadn't come across many such cases in my research. The high percentage can however be advantageous since it will tremendously increase the whitening effectiveness so long as you are not sensitive or allergic it. 

How it works  

  • The 35% carbamide peroxide guarantees some level of effectiveness. So this gel will most probably work for many people. 
  • The gel also comes in two syringes which guarantees you enough supply for multiple treatments. Most people admit seeing results after the first or second application so you will be spotting a sparkling smile before you are done with the gel. And you have 20 treatments!
  •  It is advisable not to use to much gel in one treatment.
  • LED light that comes with the kit will speed up the whitening process
  • Vitamin E swabs protect lips and moisturize them

How to use 

The kit comes with a detailed instruction manual which is very easy to follow so you are unlikely to encounter any major problems apart from perhaps, your own clumsiness. The procedure is super easy.
To start using:
  • Apply one treatment of the gel to the trays and insert to your teeth. There are two trays for the upper and lower teeth. The trays are designed in such a way that they can fit in a range of mouth sizes. Submerge the trays in warm water before fitting to your teeth.
  • Leave the trays on for 5 to 15 minutes.
  • Repeat everyday

Not my teeth.

I must admit the gel lived up to it's promise. All the praise was not a fuss after all. My teeth were a lot whole whiter just after the third treatment even though I didn't strictly apply everyday.

Pros and Cons of Smartsmile Professional Teeth Whitening Kit


  • The Instruction manual is super easy to follow.
    Unlike most whiteners the gel has a mint taste which is okay 
  • The 35% carbamide peroxide didn't even make my teeth sensitive. It did a great job of accelerating the whitening process instead.
  • The Ingredients are mostly natural
  • You start seeing results just after the first treatment
  • Coupled with the insanely cheap price, this awesome whitening kit is a must have. 


The problems you will encounter will be most likely front your end. Like not following instructions properly, fitting the trays incorrectly or using many treatments in a single day.
I personally didn't have any major problems though I understand some people might be sensitive to the carbamide peroxide.
The trays will fill your mouth of course and there is bound to be a build up of saliva. That's of course normal. But as for the effectiveness, there is really not much to complain about.

Bottom line

The Amazon hype about Smartsmile Professional Teeth Whitening Kit is not just some fluff. If you have issue with sensitivity and can't use other products like whitening strips, then this is the best option for you.
So do I recommend this product? Definitely. Get yours now and you won't be disappointed.
