Check with mirror: Look at your tongue with a mirror to see if you can detect any irregularities. If you see a growth or white film , then you should see an oral medicine expert such as a dentist , oral surgeon or dermatologist ...

Possibel: It can be thrush or black hairy tongue. It can also be inflamed, raised tastebuds. If it does not resolve in 7 days see a dentist.
