Is my tongue piercing infected?

OK. So the indent is just part of the piercing. Nothing to worry about. The white discharge is more likely than not just your body trying to put a scab on it till it heals. Also nothing to worry about. If you feel even a little worried and want to do something, try rinsing your mouth with sea salt/water mix. It should help get rid of it faster. The swelling is just going to go away on its own. After the two week period and its still there, well you should go to your doctor or piercer depending on the thing thats still there. If it has been reducing and it still there just remember that some people take longer to heal than others.
