Sensodyne Fresh Gel Toothpaste is a toothpaste that comes in a cool blue gel for people who prefer gels. Like other Sensodyne toothpaste products, when used every day, Sensodyne Cool Gel toothpaste relieves sensitive teeth by building a protective barrier that blocks the sensitivity caused by hot, cold, sweet and other contact triggers and keeps it from coming back. Sensodyne Cool Gel toothpaste has a cool refreshing taste that leaves your mouth feeling fresh and clean.
