Sensodyne Pronamel Active Enamel Shield Whitening Toothpaste is designed to actively reinforce and protect weakened enamel while delivering effective whitening results. Its proven formula helps defend against cavities and enamel wear by remineralizing enamel, offering twice as strong resistance against dietary acids from day one and providing 24-hour cavity protection against sugar acids. Sensodyne Pronamel whitening toothpaste effectively and gently removes stains to reveal whiter teeth, while its enhanced foaming action with a fresh mint flavor leaves your mouth feeling clean and refreshed. Twice daily brushing with Sensodyne Pronamel toothpaste locks in minerals to protect against acid wear, shields against cavities, and helps restore the natural whiteness of your teeth. This fluoride toothpaste actively repairs acid-weakened enamel areas, making your teeth stronger and better protected. Sodium fluoride (0.3152% w/w, 1450 ppm) further supports enamel protection by rebuilding microdamage and preventing future acid erosion.
