Review on Crest Diamond Anticavity Fluoride Whitening by Alex Hensen

Excellent mouthwash. The sensations are smooth without much "burning". Only used it for a week in combination with whitening strips and whitening toothpaste. I can't tell if the mouthwash turns white or not, but it always feels clean after use. My only reason for 4 stars is this. I'm used to rinse aid with a measuring cup as a cap. The cap on them does not perform this function. I'll admit I might be missing something, but the way the cap is designed I wouldn't use it to measure. It was okay to take a little sip though. *Of course not swallow*
