I got my tongue pierced a few days ago and theres white stuff coming out of it and it kinda hurts around the piercing hole i used mouthwash to clean it help?

Of course it's going to hurt! It's most likely swollen and trying to heal.

You need to be more specific with your cleaning habits.

You should be cleaning your mouth every time you put any kind of food or drink into it by rinsing with the (gold) Listerine halved with water.

If you get a white ring around the piercing, that's when you should get it looked at.

But it just sounds like you have to clean it better and more frequently....
