No other symptoms. Everything else is totally normal. Breathing, eating, drinking, urinaring, defecating, she doesn't seem off in anyway. I'm 99.9% sure her gums were a healthy pink color. Recently when I was out of town she stayed at my parents and got fleas which she never gets so she had been biting and itching a lot so maybe it's the friction from biting so much? Where her canine teeth overlap has always been a small black area but only where the tooth would overlap the gum but right now it's all over.

Friend, some dogs could have normal brown or black pigment in their gums; that would be normal for that dog. When we see discoloration this could be secondary to either a localized problem as in the case of certain type of tumors like melanoma. Or, even part of a systemic disease. Can chronic friction or irritation cause darkening? I have never seen this in the gums. But, in any case of chronic friction of the skin or membrane you can have inflammatory cells (macrophages) release melanin which is a chemical that will cause hyperpigmentation (darkening). So, could this have been caused by the chronic friction scratching as a result of fleas? Theoretically, I guess we can say yes. But, I have never seen that in clinical practice. For this reason, I would recommend a hands on examination with family veterinarian including a blood test to make sure everything is ok systemically.
