What Causes Redness In Eyes Along With Inflammation Of Lips?

Hi.
I've got this crappy taste in my mouth. My lips are burning, my eyes are red and feel like there's sand in them, My hair is breaking off in large quantities. I think it's my rotting molars. Now , I've kept up with my teeth but recently I had to have a molar root canal ed. It was only then did I realize that when I got it fixed that I felt great. I had so much energy. Then it must have cracked again because I was getting that super crappy taste in my mouth. Not to mention toxic breath! I have an appointment to get it repaired but have noticed all these symptoms coming back that i have had for I woulds say 15 years. I've been on puffers and some kick ass antibiotics thinking there was something else happening. I have so much fatigue. I feel like my muscles are fatigued, if that makes sense. Can these teeth do permanent damage. Is there a test to tell me I'm being poisoned by my own teeth? Help!
