I've grown up with Crest toothpaste and contribute beautiful, healthy teeth (even at 48, only 4 cavities, and Mother of 2) partly to Crest products. Never before have I felt compelled to write a review about a product, but Crest Extra White Plus Scope Outlast is the best toothpaste! My teeth feel so clean -- like they do after a professional cleaning. So glad I'm been a faithful Crest user and so glad you developed this toothpaste! Thank you!
