Sent this letter this morning to the makers of Sensodyne (GSK): Hi, I think it’s important to know this product is defective. For the past month, a team of doctors and my dentist have been trying to determine why I had a mouth full of ulcers, bubbling blisters on my mouth and lips. Sound disgusting right? After going back and forth to the doctor and being prescribed cortisone, antibiotics and prednisone, changing my blood pressure meds.. I did some searching on my own online. I exhausted everything. Someone mentioned, could it be my toothpaste? Certainly no, I had used Sensodyne for years... heck it’s for sensitive teeth! But I realized I used a different type.. Repair and Protect. After reading online, I had no idea how different this formula was. My DENTIST recommends this product! After reading pages of online reviews, I learned I’m not the only one!!! This product is like an acid that was eating away at my mouth inside and out. How is this product on the market??! What say you, executives at Sensodyne?! After 3 days of discontinuing use, my mouth is healing. My lips have shed 3 layers of skin. I’m finally looking normal. I’m so disappointed and will NEVER use your products again. Sincerely, Emily Constantine
