Within an hour after using Listerine Zero, each time a "white film" coating developed in my mouth. This coating left my mouth dry. I removed the coating with my tongue and either spit it out or wiped it on a towel. After each use, I thoroughly rinsed my mouth and everything appeared to be ok; but within an hour later the white film developed. I used the entire 1.5 litre bottle in hopes that the problem was not the mouthwash.
While having a conversation, it was sometimes embarrassing to have to "discard" this film from my mouth.
The "less intense" idea is great and I like it; unfortunately the product just doesn't work for me.
No, I would not recommend this product
