I am not a big fan of Crest's Pro-Health product line. I started using it after a dental cleaning and it created spots on my teeth. I think it's great that it is alcohol-free and therefore is less harsh than other mouthwashes. However, I just do not trust anything Pro-Health after my experience.

It lturned my teeth blue.

This product caused me to have a severe burning sensation on my tongue, as if I had eaten something too hot and burned myself.

After using for several weeks I noticed that I was getting brown stains on and in between my teeth. Worse than that, I began to lose my sense of taste and the inside of my lips and cheeks became insensitive. Terrible product.
