I had a infected tooth extracted last year and then started getting mucas in my throat. Thought I was sick or had a sinus infection. They gave me antibiotics. It didn’t go away and is getting worse. Went to the ENT and they took a scan and I have a connection problem between where the tooth came out and the sinus. Basically a hole now. When I do the sinus rinse ii can feel the water in my ear now and when I blow my nose. The dr that took my tooth out said he can do surgery and put bone back in between. This scares me too.
try chewing gum - saliva flow increase - solved issue for me
