No the sore spot it is on the opposite side of my mouth than the fistula. I had one other root canaled tooth which is on the same side as the sore spot, but that tooth is farther back than the sore spot. Like I said, I cannot see it when I look in the mirror (no white or red lesions). Everything looks normal. I have to press pretty hard for it to hurt. I only noticed it because my daughter squeezed my face. Otherwise, I probably wouldn't know it was there. The bump is very very small. In fact, I had to question whether it was even a lump, but I'm pretty sure it is. Regardless, it hurts when i touch it.
