So far, I have found nothing that helps this sticky thick saliva. Culture shows it is no longer thrush, just normal mouth bacteria...but it is anything but normal. I believe Covid attacked my mucosa and salivary glands (that's just my thoughts). I have been diagnosed with long Covid and am going to a Covid Recovery Clinic next month. I get choked on this stuff at night, I scrape my tongue several times a day, use Listerine, Perxoyl, and brush 3 times a day, salt water rinse, stay hydrated and still have this. Some days are better than others, but, it is never gone. I realize this is nothing compared to others. It's not painful, just aggravating. I'm hopeful there will be a solution for us all. Prayers....
