I decided to try something new over a month ago and bought the Sensodyne Repair & Protect. After about a week of use the inside of my mouth got really sore and I developed what I believe were ulcers on my tongue.
The worst thing was getting dry cracked skin on the corners of my mouth. I didn't notice the connection between the toothpaste and my symptoms until a week after that, so I used the product for about 2 weeks total. Anyway, it's been a month since I stopped using the toothpaste and I STILL look like I've got two portwine birthmarks on the side of my mouth the size of dimes almost. In the past month I could barely open my mouth because of the dryness and cracking.
This whole experience has been horrible. I don't think I'll be using Sensodyne toothepaste ever again.
