SmileDirectClub Pro Strength Teeth Whitening Kit, 8 Pack Gel Pens

I absolute LOVE this product. I am almost done the treatment and have not had any sensitivity whatsoever. My teeth have always been very sensitive and other tooth whiteners have really harmed my enamel. The whitening is obvious to me, and given that one treatment only takes 5 minutes is a plus! Highly recommend!

You will see the difference after your first use. Just follow the instructions and be sure to BRUSH YOUR TEETH regularly, i.e... (2-3) times daily. At least brush before you use it. I've gound that after time expires and I remove the tray, I keep the formula in my mouths and swiss it around in my mouth I do so for my rear teeth because it works for me. Some people have smaller mouths/smaller teeth, and your tray may be just right or even feel too big. I'm a big man. I also place pieces of paper towels along my gumline when applying the formula in order to keep my rear teeth from getting wet with saliva while applying AND like i stated before the tray is a bit short, thus the light does not reach my rear teeth due to the interior of the mouth covering the outside of my teeth when I close my mouth. Works For Me! The first time I used it, I was happy with the results, but I missed doses a lot of times... so i gave it a second chance and followed the directions totally, and the results have been magnificent. All my teeth are whitened for that open mouth big laugh like when we see folks get caught on camera and we're looking at their back teeth to confirm if all of them are as white as the front teeth. lolol

I love these whitening pens! I recieved a free blue light and whitening pens when I got my teeth straightened through Smile Direct and I absolutely fell in love with how easy and quick they are to use. It's great that I can keep my smile bright and white without having to visit the dentist.

My teeth look brighter but still not Hollywood white. I do like the convience of these however and they travel easily. I have the whitener device as well.

It DOES whiten your teeth, the question is how much? It whitened mine several shades, but they are not "white" yet. And that is after the first 8 day treatment.

The instructions says that you need to put the gel on the 6 teeth at the top and 6 teeth at the bottom.. and there is sufficient amount of gel for only the front of the 12 teeth. The problem is that if you have a big smile, it looks bad because you can see the difference between the whitened and stained teeth. Also the back of the teeth is still stained. The light to use with the gel is made for the front of the teeth. I'll not buy this product again.. I'll go with the strips which covers more teeth, whitens the front and back of the teeth and is a little cheaper.

The product works great. I have noticed that the pens provided with the retainers hold much much more of the whitening gel than the extra set purchased after. In a world promoting recycling and a low plastic footprint it is not encouraging to see that the plastic packaging outweighs the content/product by far all while there is already a more environmentally friendly whitning pen that holds more of the gel available and somewhat in use.

This is my first application of the product. While I can see a difference, my teeth are not as white as the models they use in their advertisements. Perhaps it will take a 2nd application to get there when I do it again in 6 months.

Multiple pictures clearly display it comes with 2 boxes. I only received 1 with the pens. No applicator or lights guard. How am I supposed to apply this????

So disappointed. Yet another product saying it would whiten 9 shades whiter. Have used x 1 week. Followed directions. No change. I'll keep using. Doubtful for the results advertised.
