LISTERINE LISTERINE WHITENING QCK DIS STRP - 56ct

It seems these strips are being discontinued. Too bad because they are the best I've used. Not messy like the other brand. Fresher, cleaner feeling after use than the other brand. They dissolve in place and don't slip around and require repositioning like the other major brand.

I don't know if this box was sit in the sun or what...I had to go thru 4 strips to get a usable ONE. It meled and embedded to the packaging..I never had this problem before when I buy it from CVS...My store was out of it..why I bought this from online.

I was looking for a way to whiten my teeth and was willing to spend a bit but these are relatively inexpensive. The directions tell you to whiten two times daily until all of the strips run out. I'll start by saying they are relatively easy to put on (as long as you don't put the wrong side against your teeth, then you have to throw the strip out because it gets all sticky). Now I don't have sensitive gums, I don't have a problem with food or hot or cold bothering my teeth. But I never got through an entire week of wearing these (you're supposed to wear them for two). Probably around day 4 or 5 when I put the strips on my gums were on fire. After you put the strip on and it gets a little wet you can scrape it off of your gums so it's just touching your teeth, but this didn't seem to help. I've tried finishing the box several times since I started, but still never able to get through all of the strips. All in all I think they are cheap and easy to use, but they burn like hell.
