I have one small sore in my mouth, it's located below my lip at mid tooth level, it's clear with black dot in the center, it's not painful, and I've had it for 8 days and I'm beginning to wonder if it's something serious or just something viral.
I don't smoke, but do drink 3 nights a week, with excellent health, and no history of mouth sores, or family cancer. I'm married to same woman for decades, and we are not sexually active outside our relationship.
