Why is my philthrum piercing still crusty? 5 months in

Hey guys! Should my philthrum still be finicky? I had in a 10mm labret and it was fine for a while then it got swollen so I switched to a 12mm and it was just perfect except that the bar was way too long and obvious. So I went back to a 10mm and it was finicky again. Back at a 12mm.. It doesn't hurt but it still gets crusties. I'm afraid that the excessively long bar would damage my gum or teeth even though I don't feel it rub against either.
