tooth pain diagnosis?

Asked by toothpain (5) January 1st, 2007

I have been experiencing pain near my upper tooth (number 13+14, near the back). Even though the tooth and gum area is the epicenter of the pain, I can feel it in my head and sinuses as well. The pain is limited to the left side of the face and my vision becomes blurry in my left eye. I have been to the dentist office four times since my first tooth ache and they haven't been able to solve the problem. They identified weak enamel and covered it with fillings. All the X-rays show no other weak spots, cracks, or problem areas. They now suggest I see a root canal specialist. Has anyone experienced anything like this? Are there any tests I should request or pointed questions I should ask my dentist or doctor?
