Hi,
I read about the risk of cancer linked to Listerine and alcohol based mouthwashes in the free Metro paper in the UK. It was a surprise to me, and when I got home I got rid of my listerine.
It seems that it is old news though.
It is strange though, no one ever mentioned it at the hospital.
I have found some alcohol free mouthwashes now, and they taste just as nice. But who knows what they will say about those in a few years?
