I also have Sjögren's and I use the zylimelts. They help overnight. My mouth is very sensitive to most foods. Even water is painful at times. I don't see any sores in my mouth but any fruit with acid is painful to eat and any food that is crunchy or dry is painful. I can't use some of the mouthwash alternatives because they burn too much. Even the Biotene without alcohol burns. I might check into having some allergy tests done. I don't know what to do!
