Prior to trialing the range I was not aware of the effects of acid on my enamel. Now that I have used Pronamel there is no turning back! I love that I can now safely indulge in my favorite healthy foods without being afraid of the effects of the acidity on my enamel. My favorite of the 3 variants is the Gentle Whitening as I always look for toothpaste to enhance the whiteness of my teeth. I will definitely recommend Pronamel to everyone I know as it is effective and will definitely continue to be a part of my daily regime.
