Whitening Tooth Strips - SwissWhite Smilepen Power Whitening Strips
I have been using these whitening strips for the second day now. As mentioned here, the results are visible after the first application. Before this, I used whitening strips from another brand and I was extremely satisfied with the results.
However, I will deduct one star for the whitening gel. After removing the strip, it is not easy to wash off the gel right away. You need to brush your teeth, which is not very convenient if you don't have toothpaste nearby. Rinsing with water is not effective. The other brand was much more comfortable and didn't have this unpleasant gel sensation. But these strips do their job. Here are the results after 1st and 2nd day of using these strips for whitening.
