I have had chronic headaches for about 8 yrs following a car accident and have received all the conventional type treatments for migraine (triptans, narcotics, seizure meds, etc) and I have also seen an unconventional chiropractor who practices a form called nucca. I still havent found significant relief and i did question my dentist about TMJ when I first started having the headaches and she didnt feel there was a correlation. However, i recently found a website run by a dentist who limits his practice to treating headache pain and states that he has advanced diagnostics, including xrays and a doppler in which he can accurately determine if TMJ is contributory to the pain or perhaps the main cause. However, i dont want to be taken and I know that the internet is full of people claiming that they have found the 'cure' for a particular ailment. Are you aware if there is some legitimate data behind diagnosing TMJ dysfunction via xrays and doppler. My prior dentist really just palpated the area while I clenched my teeth. I dont know how that can be accurate of anything though?
