As a Listerine user, I have not been unmindful of potentially adverse effects from using this product--specifically oral cancer. I have asked health professions, including my dentist, about this and have been assured the product is safe. My mind is open to being changed, but for now, I continue to use it with confidence.
It is worth nothing that Listerine is not a new product; it has been around for more than a century. I am inclined to think that if it increased the risk of oral (or other types of) cancer a great many people would have been impacted long before I came along and Listerine would have been identified as the causative agent.
Rinsing with Listerine is the first or second thing I do every morning.
