Review on Sensodyne Pronamel Gentle Teeth Whitening Enamel Toothpaste for Sensitive Teeth - 4 Ounces (Pack of 3) - Rehardening and Strengthening Enamel Benefits by Melissa Gonzalez

I love this toothpaste but the cap design has become useless. Over time, the paste will build up in the grooves and clogs, making it difficult to close and latch. On top of that, someone thought it would be a great idea to reduce the thickness of the plastic tube itself, so the whole package curled up when empty, making it difficult to make a purchase on it. Real pain. UPDATE: Not keen on wasting money, I suffered from using all three tubes. I won't be buying it again because I don't know if it's Alpine Breeze (very chemical and not quite minty but kind of a synthetic counterpart that burns) but on all three occasions when I was at the end of the tube, I did developed sick mouth ulcers and had to throw it away. Not a big fan.
