White coat on my tongue and doesn't go away?!

White coat on my tongue and doesn't go away?

I always have a white coat on my tongue and when I try to scrape it with a tongue scraper, it doesn't come off. Some come off but it's always there like it's doesn't come off all the way. There are always still remnants left. What to do?

I had the same thing and it turned out to be thrush ;and i thought only babies had got this..I am on a discus inhaler for asthma and if you don;t rinse your mouth after you take it it causes thrush.Antibiotics cause it also...Go to your doctor so you can go to the pharmacy and get something for it.If it;s not this your doctor can find out what it is and get you well soon... don;t delay and call Monday...good luck.
