I need some help because this swollen gum on the right side on the back of my mouth is irritating me everytime I eat or talk. It's been there for about a week. It's just pushing against my cheek and it gets bigger everytime it gets touched or when I eat. It's just on that one spot and there is a very dark, sort of black or dark red, area on it that appears to be on the inside of the swollen gum. The gums on this area is loose a bit and when I can pull it slightly away from my teeth and it bleeds from the opening, so I avoided that.
I read on some sites that some toothpaste can give allergic reactions to make the gums swollen, and I don't know if that's the case, but I have been using a new toothpaste. It's in chinese so I don't know what it is, but I'll ask my parents later or something. Even so, why doesn't the toothpaste make all the gums in my mouth swollen. Another possibility is that it's my wisdom tooth coming out, but still over a layer of gum.
I'm just too confused, and will make a dentist appointment after your suggestions to see how important it would for me to go because I'm quite busy this week.
