I tend to write long reviews, so here’s a quick list of positives and negatives of the whitening pen. This may also answer some questions you have about using the whitening pen:
Positives:
-Actually whitened my teeth!
-No bad taste
-No irritation/pain
-Easy to apply
-Nice packaging
Negatives:
-Did not last as long as the box said it would (lasted 1.5 weeks instead of the 30 usages the box promised)
-You have completely to dry off your teeth and then paint on the solution on each individual tooth (I personally didn’t mind this. It just took a little while to do)
-If you paint over wet teeth, it will ruin the brush
-The solution easily clumps up in areas on teeth after it dries (this didn’t bother me much, but thought it was worth mentioning)
Okay so here’s my more in depth review:
I’ve tried just about every whitening toothpaste on the market, charcoal, baking soda, and more, with no results. I heard about this pen and thought I’d give it a try. I was a bit nervous because I can have sensitive gums, but I felt no irritation whatsoever! The pen lasted exactly a week and a half before I used it all up (so it did not last the 30x stated on the box!). In that time, I can honestly say my teeth look whiter! I was pleasantly surprised. Believe me, the yellow on my teeth was stubborn! I may purchase the pen again to whiten my teeth even more.
However, I noticed a few things about the pen that might be considered negatives to some people. First of all, you have to COMPLETELY dry your teeth before “painting” on the whitening solution with the pen. Otherwise, the solution gets all clumpy and dries up on the brush, which will ruin it. Also, be aware that the pen paints this solution on your teeth and sort of leaves a thin film/coating over your teeth overnight. The solution doesn’t have a taste or anything, but you will definitely want to brush your teeth in the morning to get it all off. Also, be aware that the solution will clump up in places on your teeth when it dries.
I was not aware that that was how the pen works when I bought it, but looking back, I noticed that most of the negative reviews focused around the white clumpyness of the solution on your teeth. This honestly didn’t bother me much, though it was a little bit of a hassle to dry off my teeth and get an even coating on each tooth.
Additionally, you will only be able to whiten your front teeth, as it is to hard to dry off and paint the teeth at the back of the mouth.
Overall, I am pleasantly surprised and impressed by this whitening tool. I’ve tried so many different things and this is the first that has worked! If you are okay with the few “negatives” than definitely purchase this product! I would purchase this again!
As a note, I tried to take before and after pictures but because of bad lighting, they didn’t turn out. But I did see a huge improvement in my teeth’s whitening!

Works! I'm impressed
I am a first time user of teeth whitening, so I wanted to track the progress. The first picture is the before, taken after brushing my teeth and flossing. The 2nd photo is the after leaving the whitening treatment on my teeth for about 4-5 hours. Even after just that amount of time I can see a noticeable difference! I'm excited to continue using this and see what else it can do for me. I'm a coffee drinker so my teeth get yellow, no matter how often I brush or floss.I followed instructions to dry teeth with a paper towel and did one row at a time while keeping my mouth open the whole time, worked for me! The solution left a light film on my teeth but it didn't bother me at all.Overall I'm happy! And hope to see progression with more continued use.

I like this product because it’s very easy to use and unlike other traditional teeth whitening strips, you can just apply this and go to sleep. Then you just wipe the residue off in the morning. Thus, it’s easier to find time to use this product.
However I still have this product a 3 because I find that it is not as effective as some of the teeth whitening strips. And, you may need to use the product a bit longer to see the effects.
As you can see in the photo, it is small and easy to keep out on your bathroom counter. It also comes with a little stand which is helpful because you need to keep it stored standing up to keep the brush fresh/prevent the product from getting damaged.

I should have taken a photo from the beginning. But even after the 3rd and 4th treatments, you see a difference. Reviews say it runs out sooner than anticipated. If it does, I don't mind because it did a mighty fine job in the 4 so far!
The coating leaves a texture on it. I like it. This product is way more convenient than the strips. I'm sure you're not supposed to eat or drink while wearing the treatment. I drank water. Didn't rub off!
Honestly, I was skeptical at first. Glad I decidedly to purchase anyway. Besides the results, the best part about the product is my gums aren't raw. The strips cover your teeth and your gyms. I couldn't do treatments two days in a row. This pen has you put the coating on just the teeth.
Toothday is the day you should buy this!

After 1 week, there is no noticeable difference. The duration may be on a case-by-case basis. But if I personally need longer than a week before any changes start taking place. Then this product has fallen short of its advert claim of "Remove 15 years of stains in 1 week".
