Inflammation above the left central incisor, in the gum.

Hi,

I've had a root canal for almost 6 years now. It all started when I chipped my tooth after falling off my bicycle in which my left central incisor wass chipped. Nothing was not noticed untill a few days later, when my lip started to swell up, it was found that the part of the tooth that was chipped was pentrated in to my lip. Of course I didn't feel any of this of the day of the accident due to shock. A month later I got an abscess above the tooth that was chipped, it caused severe pain. I went to the doctors, he admitted me to a professional at a dental hospital. He told me that nerves in that tooth are dead, did a root canal. Then starting draining the infection out, after this was complete the pain was gone, but the abscess was still there, so I started to see him weekly and he continued to drain it. It started to dissapear, in which he gave it month. When i went to see him the abscess was gone, he said come back in 2 months, I went back and he said it was all clear. About four years back I got inflammation above the tooth, it went all red. No pain is felt though. I've started to feel unexplained anxiety, in which my heart has started beating fast, and recently a shortness of breath, could any of that be related to sepsis or bacteremia? I went to a dentist on tuesday and he said I have a chronic infection of some sort. I was slightly confused, in which he said that root canal was not completed properly which has caused a chronic infection which can defect the teeth around it. I was in complete shock, this has been going on for years. He has appointed me to a specialist who is yet to have gone in contact with me, supossivley contacting me via post.

I've added a small graphic showing where about the inflammation is on my gum. It's the dark red area with the white dot on it.

Help, do I have bacteremia or sepsis?
Are my teeth in trouble?
Has anyone experienced this before?
Is is fatal?

My dentist did not explain much as he was really busy that day.
