Over time, acids in your diet can weaken your tooth enamel through a process called demineralization. New Pronamel Intensive Enamel Repair Extra Fresh toothpaste is an advanced formula in enamel care that inhibits demineralization and improves a process called remineralization, actively repairing acid-weakened enamel and protecting it from future erosion. How it works is simple! Pronamel Intensive Enamel Repair toothpaste for enamel helps minerals penetrate deep into the enamel surface, naturally rebuilding strength in areas of erosion for strong, healthy teeth. Plus, it gives you fresh breath, so you can feel confident about your smile every day. Pronamel toothpaste is specially formulated to help protect enamel against the effects of acid erosion from everyday acidic foods and drinks such as wine, fruit, or soda.
