Whiter teeth in no time

It is both cute and convenient to carry around if you want to take some strips with you on a possible trip. They work quickly, so if you are going somewhere special and want whiter teeth in no time, this is the product. Just put them on for 15-20 minutes, and they will already be much whiter!


Affordable, quick, and easy to use

Almost obsessive I start trying whitening toothpaste. However, I did not see immediate results. I also asked my dental hygienist to polish my tooth longer, but that did not do the trick either. I pinned my hope on Smile lab. I immediately saw the difference, especially after using all strips.

The staining is gone

My teeth stain pretty fast because I drink a lot of coffee. When I use the Advanced Teeth Whitening Strips the staining is gone in only 2 sessions. When I follow the entire treatment my teeth are a couple of shades lighter. I keep the result up with Flash strips once in a while in between my two full whitening treatments every year.
