Please help get this infection out of my mouth

I never thought in a million years I would have to do this..especially asking for myself.  I have several disabilities and life is unaffordable at times. I have been on disability for 3 years now but was in excruciating pain not working for 6. I have a infection in my tooth canal that won't go away. It started off as a cyst that my dentist operated through my gums since my tooth itself is fine. This kind of operation disability won't cover. Sadly after that one the infection came back. I went to the hospital to get a CT scan..bone scan. My dentist refused to do another operation for he felt it was stemming from my nose. After several visits to the ER...4 doctors..two other dentist...they felt it just had to be cleaned out again. Just after new years I had the operation again. Both operations cost 1200$. My dentist cut open my gums again to clean it out. Recovery is hard since I have fibromyalgia, neuropathy and osteoarthritis and just a simple cleaning hurts so much. It a major dental surgery. About 3 weeks ago I started to get pain again. I was seriously praying hard it wasn't the infection that was coming back or never left. It definitely is. Now no dentist can get this out. It also looks like it spread to another canal. This is all internally for my teeth are fine. So I know have to go to a endodontis. I have a appointment today that will cost 295$ plus tax..I assume for the consultation and x ray. I can't afford this at all. This is also just the beginning. I will have a better idea of how much this will cost me by the end of the day and I will change the $ amount to fit the estimation. It's my two teeth in the front. No dentist wants to pull them for there's nothing wrong with them. I also can't afford to replace them. I would seriously be traumatized if I have to. There's only so much I can take. So here I am asking kindly if anyone can help me out. Even if it's just 5$. Anything helps for I am in the negatives in my account already and seriously don't know how I'm going to cope and do this alone. Disability won't help me with special dentist work...which isn't fare at all for this is not cosmetic in any way. Please help me get this persistent infection out of my mouth after 2 failed attempts. I have had this for almost a year now. I have taken endless antibiotics and nothing is killing this infection. I just want this horror to end. I have no issues in showing the bills and estimates to what's to come. I get the first one later today. To who ever helps me I thank you from the bottom of my heart and one day I will pay it forward for I have been doing this in my own way for years now. Update...so now sadly I have to pull these two teeth out. The infection is eating away at my bone and I have cracks in the teeth that no matter what can't be cleaned out. This is why it keeps persisting. I have been crying since I saw the maxillofacial surgeon yesterday. Several dentist and the endodontis told me I could save them but sadly I didn't have the money so now they must be pulled. It will cost 1450 to pull them and clean the infection from the hole in my jaw and about $1300- 1500 to get some partial dentures. The teeth are in the front and very visual. I have been using laughing and smiling as a coping mechanism for my excruciating pain I normally endure daily and now I can't even do that. So I keep praying my GoFundMe will grow and you all can help me smile again.
