Sensodyne Pronamel Intensive Enamel Repair extra fresh toothpaste is proven to drive minerals deep into the enamel surface to actively repair acid-weakened areas of the enamel, leaving stronger, better-protected teeth. Acids in modern diets can weaken your enamel surface. Over time, this can lead to your enamel thinning, allowing the yellow dull dentine layer underneath to show through. Once your enamel surface is weakened it needs extra care for the future. With twice-daily brushing, Sensodyne Pronamel Intensive Enamel Repair toothpaste helps to actively repair acid-weakened enamel and lock in minerals to protect against the effects of acid wear, protecting against cavities and keeping your gums healthy. Suitable for sensitive teeth.
