Unfortunately, I recently tried the new Crest Pro-Health Night rinse, to find it did not agree with me. It createst a most unusual sensation on my tongue, the tip felt like a canker, and left an irritating film. I'm a big fan of Crest tooth-pastes in general, and also enjoy Oral-B products. This rinse prompted me to request a refund, as I could not use this product. I did however enjoy the Pro-Health Tooth paste.
