I went to the dentist and they gave me sensodyne toothpaste for my tooth sensitivity, right after I started using it my face and lips became swollen with reddening of my cheeks (beat red). After 2 days I began to get sores in my mouth making it very hard to eat. Could this be a complication from beginning sensodyne, I had no other changes in my diet medication or other changes, deodorant laundry detergent, perfume or the like. Went to dentist and they had no clue as to the cause. They prescribed first mouthwash blm. Do you think this is caused by the sense dyne which I stopped using but the symptoms are only slightly resolving?
