Last week i recieved upper dentures. Been wearing them all week as the doctor told me to. Bleeding has stopped and the dentures fit fairly well. The problem is that there is a clear viscous gel-like substance in my upper mouth that has a bad odor. What could be causing this and how can I help the situation? I have tried to brush my mouth gently with toothpaste and rinse with mouth wash . helps temporarly but comes back. Last time I check my tongue was covered with this and turned my tongue almost white. I brushed again and the tongue is now back to normal and I removed as much as i could by brushing my mouth again.
