Is oral trush ( on tongue ) dangerous? can it make my tongue swollen, and deadly? i know its a silly question. but i'm just wondering.

Thrush not a threat: Thrush can look horrible but it is relatively harmless and with some good antifungal treatment should melt way in a couple days. Looking for the cause of the thrush would be important since u don't want it to come back. Hope u can see your regular doc to get some treatment for that. Note alot of times patients think they have thrush when it's not-- try rinsing with water frequently.
