Hi.
I am new here, so bear with me.
I had a filling done on my second to last molar on the top right, about 7 years ago. Dentist said the filling was deep and I had a hairline fracture as a result. He said someday we should cap it. Fast forward to two years ago. I've since moved, had kids, etc. go to the dentist who determines the tooth in front of that molar needs a root canal. Which I do, but don't cap as I cannot afford it.
Meanwhile I've stopped really chewing on the right side because I always have a sharp pain, whether from tooth that is cracked or the root canal one, I don't know.

Last year I start getting facial pain, like sinus, and am spacey and foggy headed. Go to ER. They do a CT, and send me to an ENT. ENT says I have a cyst in my right max sinus and some septum issues. We opt for surgery. Had that May 1st. Facial pain is mostly gone, but still seriously fatigued and foggy.

Follow up with GP who does an MRI. They see white matter scattered spots, indicating auto immune or post infectious. Do blood tests for auto immune, all negative. Now they are referring me to a neuro.

I'm freaked out! Still foggy, still can't chew on right side. Started process to cap those two teeth, but now I'm hesitating. Would it be crazy to think maybe it's all due to these two teeth?? And if so, what do I do??? My dentist says he doesn't see any infection, I asked months ago. So I doubt he's gonna help me!

And seriously google really scares a person.

Thanks for reading.
