What can I do to get help from the VA?

In jan of 2005 I was in shindand Afghanistan when I got injured, blunt force trama to the left side of my face knocked me off a water tower that just about killed me,... To those soldiers that took charge and got me to the doc. I can never tell you enough, Thank you. I have never been one to say I'm a hero, I believe we are normal people trying to do our best in an very unique situation as a firefighter I've had several soldiers thank me for what I did, it humbled me when I was the one on the stretcher, looking up and seeing your faces in that scary situation, I was glad you were there. Anyways, my teeth were to put it mildly were in a great need of attention. The military concentrated on getting walking normally again and correcting a few other issues. I was told the va would take care of the dental. But it's been 10+ years and I am quite upset with the process! they have turned me down every year for an injury I incurred in the line of duty. I really don't know what else to do. Please help me I do not know what else to do and I can not afford the civilian doctors.
