Is it bad if your tongue is yellow after getting it pierced?

Its infected... you have to keep moveing it constantly and clean it to avoid this. if its already happened take it out and go see a doctor asap, or say bybye tastebuds. Yellow coloring in the tongue can be an indication that you are overusing mouthwash. Make sure you are using non-alcoholic mouthwash to avoid chemical burning of the tongue, and only rinse after each meal. Yellow DISCHARGE coming from the piercing can be a sign of infection, but not usually a yellow film on the tongue.
