Tongue piercing

Even though my parents don't approve of it. I already got a tongue piercing. Don't tell me about waiting I am 22. I don't need their permission but I am not going to let them find out. yes I live with them but I also live near my college. So on to my question. ~•~•~•I got my tongue pierced 2 days. If anyone has any advice or tips for that would be greatly appreciated. It doesn't even hurt. Managed to eat pizza. And I have white stuff around the bottom ball. Not sure if I should be worried about that.
