This works great. I could tell after the first use, my teeth were a shade lighter. Read more

Im almost done with the first pen, using about 2x a day for 1.5-2 weeks. It took about a week or so to see any difference so you need to be patient and consistent with the product. My canines have always been significantly yellower than the rest of my teeth and my bottom front teeth were a problem area as well. Now my teeth are a couple shades whiter (most noticeable in the yellowest areas). Im not sure how white your teeth can become with this product but it does work on yellowed areas. It is slightly annoying to use since I have to hold my lips away from my teeth while the gel dries but other than that its easy to use and apply. I'm definitely not a fan of the flavor, very strong peroxide taste with a tinge of peppermint. I suggest spitting, not swallowing, after the application dries. Read more

I've tried other whitening products in the past that took months to work. I've used this a total of 5 times and my teeth are already dramatically whiter!! I think my favorite part is it is extremely easy to use. Also, not have to keep it on for very long is definitely a huge plus! It is the most convenient way to whiten your teeth. Read more

Here is my honest review after using this product for two months. When I first got the product, there was a "coupon" inside for 2 free, additional whitening pens. In the company's defense, there was no quid-pro-quo, meaning that they did not require a positive review to claim the free offer. But, I was wary because anytime I have encountered these "free" offers before, the product has turned out to be a dud. Because other teeth whitening systems have caused me discomfort, I used the gel pens once/day, in the morning, after brushing and flossing. I followed all the product's directions to the letter. Here are the pros and cons. PRO'S: 1)I have sensitive teeth and gums, and other whitening products have caused discomfort. The iSmile pens are gentle. The gel does cause a little burning if you accidentally get it on your gums or lips, but overall, it did not cause sore teeth or gums; 2) The pens are extremely easy to use. You just brush on the whitener after cleaning your teeth and wait 60 seconds for the whitening gel to dry 3) They do subtly whiten. I did not have extremely stained teeth, and after two months of use, I would say my teeth are one shade brighter. CON'S: 1) The iSmile pens don't whiten all that well. One shade brighter after two months of use? That is not miraculous by any means. And it is not the "several shades whiter" as promised by the packaging; 2) The iSmile pens are supposed to have a peppermint flavor to mask the taste of the hydrogen peroxide. The peppermint flavor is basically non-existent and you will still get than unpleasant peroxide taste. In conclusion, these are just "ok." Maybe if you used them several times a day or applied the gel at bedtime, you would get better results. But, I was hesitant to do that with sensitive teeth and gums. If you are looking for subtle, easy whitening, these do work. But I am going to try a different product in the future. Read more

It’s very early on, but I can tell how this product is whitening my teeth already! I’ll be posting and update in a couple of weeks!! The flavor is very tolerable, almost non existing, and it’s so easy to use. Read more

The pen is easy to use with very good results and did not irritate my gums. The flavor is so/so but it wouldn't keep me from purchasing again which I plan to do. I saw results after the first use and was pleased. Read more

No difference at all .. used both pens ... had some gum sensitivity... Read more
