The white stuff is not puss it is lymph it is part of the healing process, I had mine done 6 days ago, and I have some white lymph around the bar, but just use mouthwash watered down (1 part mouthwash to 2 parts water) and also clean the tongue bar and around the bar with a soft brissled tooth brush ( a babys toothbrush works wonders) I just dip the tooth brush in the watered down mouthwash and just wash around it :) the pierced told me I can change the bar within 10days and the swellen will be down within 4 days (which it was) I also worried about the whitish "puss" but I was assured that it is perfectly normal and part of the healing process :D
Hope this was helpfull..
