I have a white/yellow patch on the back of my tongue. I dont have a sore throat or anything, just a coated tongue. I am scared because when searching for white tongue on the internet, thrush comes up as a possible HIV symptom????? If i scrape my tongue with my front teeth, some of the stuff scrapes off. Please help how do I know if i have coated tongue or thrush???
First buy a tongue scraper and try it for a few days, that stuff you are seeing is probably just bacteria filled ick. Thrush is common in babies but can occur in anyone but is usually present in other areas than just the tongue, such as the cheek area. A general dentist can probably help you, if not he may refer you to a Periodontist who deals with diseases of the gums and soft tissue. If it were an infection, he would be the one to see.
