It has been 4 days since I developed some pain on my gum between 2 of my tooth (canine and lateral incisor). It is not extremely painful, only if my lip rubs against it or if I touch it.
There's a really tiny ulcer-looking sore (like a dot) on that area. It's literally at on the edge of the gum where the teeth meets. Today, I found a tiny ulcer on the right side of my tongue
Is this a possible sign of an STD like syphilis? I had oral sex 10 days ago
