I've been using the sensodyne pronamel toothpaste ( daily protection) for a week and I can bodly say it is effective for me I have sensitive teeth which makes it hard for me to enjoy glass of cold water in the morning or gubble down a cup of strawberries without them being too sweet for my teeth.. I'm so glad I took part on the pronamel because now that my teeth are protected from enamel erosion I get to enjoy healthy fruits all day long with no pain no sweet tooth irritation. I highly recommend sensodyne pronamel for everyone.
