Crest is the #1 dentist-recommended toothpaste brand in the United States — backed by over 60 years of clinical research and dental professional trust. Available at Beauty Riche with same-day shipping.The Activated Foam technology creates an activated foam on contact that penetrates below the gum line — reaching the bacteria in the early pocket spaces between teeth and gums that conventional brushing and toothpaste cannot effectively address.

Stannous Fluoride (the active form) provides both cavity protection and gum health antibacterial activity.
