What is the difference between crest whitening strip and Listerine Whitening str!
Question: wot is it
Answers: wot is it
The main difference is that the Listerine strips are dissolving - every component of the strip, from the film itself, to the "medicine" on it is designed to convert to oxygen upon making contact with your saliva. This makes it safe to swallow and will not harm your insides.
The packaging implies that they dissolve in 5 or 10 minutes, sometimes it can take longer in certain parts - like if you have uneven teeth, some will get stuck and either need to be brushed or rinsed away. The other answerer mentioned that they can sting - and yes, if they come into contact with your gums, especially if they are not 100% clean, you'll notice a slight sting, and if you look closely, you'll also see some bubbling action, similar to putting hydrogen peroxide on a cut.
I never used them for the entire 2 weeks recommended, only one week, as I was concerned about the safety of my teeth. I did notice results, however, and I personally think that the listerine strips provide a more natural shade of white than the crest strips.
Really nothing except listeren is always stronger, my dentist said that its bad on ur teeth anythong that stings ur mouth when u use it is bad for u
