Review on Colgate Total Pro Shield Mouthwash Peppermint by Patricia Muller

This mouthwash contains an ingredient (CPC (cetylpyridinium chloride)) which is known to stain some people's teeth brown. That happened to me. I've been using mouthwash twice a day (as directed in the instructions) for a few months now as I've been unable to see the dentist in the last few months of the pandemic. My normally very white teeth are now heavily discolored. They look like I cleaned them with chewing tobacco. At first I thought the brown color was from drinking coffee, but after studying the CPC I realized it was because of it. It will cost me a lot of time and money to change something. I strongly advise people to stay away from this product.
