I can't understand how one can do this.. I know I couldn't. I have enough pain when I bite it. Maybe I'm just a big pansy.
Anyways yeah, even though the mouth is the fastest healing part of the body. Still gotta keep it clean, wouldn't wanna lose that tongue. The person that did it should offered advice on what to use to keep it clean and an anti-bacterial. But it sounds like if they didn't, all the advice is right here
