Good Afternoon! My Name Is Sabrina, I'm 18 Years Old

Good afternoon!
My name is Sabrina, I'm 18 years old and I'm from Romania. I'm writing because I'm desperate and I don't know what else to do.
Everything started in September 2015, when I woke up with strong teeth pain. It was located at all the four upper incisors and I was unable to eat, even on my molars, because my incisors would hurt. After 2 days of agonizing pain, I decided to go to a dentist that told me that I had bruxism, so he made me a teeth protector (I don't know how else to say it in English). Even though I wore it every single night, until this day, the pain didn't disappear, but it only got worse. So I went back to the dentist and he told me to get an x-ray. When I came with the result, he told me that everything was fine and that I should keep wearing the teeth protector until the pain disappears.
Unconvinced of his diagnosis because I lost 3 kg and I could barely eat soup with a straw, my parents scheduled meetings with 8 dentists in the following months, all telling me that they haven't seen such a thing in their entire career.
The next step was to visit a neurologist that recommended me a head MRI, thinking that my problem was related to my trigeminal nerve. After staying 2 hours in the MRI tube and thinking that I have something serious, the doctors told me that everything was fine and that I only had some traces of melanin loss.
Desperate with the pain only getting worse, I spoke with an orthodontist that agreed to look at my teeth. He claimed that there was no need of braces, even though my front teeth aren't really straight.
Then, something new happened: my teeth didn't hurt simultaneously. For example: one day I would feel strong pain in the left incisor and the next day, the pain would move in the front incisor. I also observed that even a gentle touch in the palate would cause unbearable pain to my teeth.
Weeks later, when I looked in the mirror, I realized that whenever a tooth hurt more, the gum above it would have a red pronounced trace, so I went to a periodontist...nothing was wrong.
So I gave up. One year had passed from my last visit to a dentist. The only doctor that told me something was a osteopath, that suspects a palate fracture. I don't know where else to go or what to do.
I can't use my front teeth, I can't bite even from a banana, they hurt every single moment of the day and the symptoms haven't changed.
PLEASE HELP!
