My dentist gave me a trial size after a cleaning, so I used it everyday for a week before bed. Every morning I woke up with a white film all over my teeth, gums, and inner cheek. I thought perhaps it was maybe an old sample, and later bought the full-sized Zero at the store. But, when the white film continued, but thought that maybe it was just me, or that something was wrong with my mouth. Well into maybe three weeks of usage, I finally convinced myself that it ISN'T just me. Reading the other reviews, it's interesting to see that this is an overwhelmingly common issue. Although I did not like the burning feeling of the alcohol in other products, I will gladly switch back now that I know there is something chemically wrong with this one. I wish I could get my money back, or be allowed to switch to another Listerine product, I'm so disappointed in this product.
No, I would not recommend this product
