'The acids in your diet can weaken tooth enamel in the tempo, exposing a dull yellow layer and making it more susceptible to further damage. While any fluoride-containing toothpaste helps prevent this erosion, Intensive Enamel Repair, Pronamel's most advanced enamel care formulation, has been shown to actively help repair acid-weakened enamel and protect teeth from future acid erosion, effectively removing stains to help restore teeth to their natural whiteness. It works by locking in repairing minerals that are deeply absorbed into the superficial struttura layer of the enamel to help repair microdamage and rebuild enamel strength, leaving teeth stronger and more protected.'
