    Crest White Vivid --potentially damaging to enamel

    The Los Angeles Times reported on a study of 26 whitening toothpastes published in the Journal of Clinical Dentistry:

    Crest White Vivid ranked 17th in terms of cleaning but was the fourth-most abrasive. Anything with an RDA (relative dentin abrasion) score above 100 is generally considered highly abrasive, and anything above 150 is considered potentially damaging to enamel. Crest White Vivid scored above 200.

    This should explain why the PG cheerleaders are walking around with no teeth.
