Hi, about 3 days ago I noticed that I was having pain in my bottom gum. When I look at it, there is what looks like a small hole there in just that one spot. It looks to be a little swollen there too. I also recently got my tongue pierced before I noticed the pain. I was wondering if that may have anything to do with it. The pain is bearable, it's just irritating because I've always had healthy teeth, never had a cavity, nothing. Is this something I can take care of at home or should I make a dentist appointment? Thanks !
