I have mandibular tori. How to get a painless x-ray?

Hi doctor,

I have relatively large mandibular tori, which are nearly touching. They have always been rather sensitive, like when I am eating chips, a sharp piece pokes them. I just went to the dentist and got those new digital bitewing x-rays, which hurt my tori as there is less room in my mouth. I have a large dark red bruise along my lingual frenulum and redness or soreness on both tori. Neither the x-ray technician nor the dentist seemed to care that I was in pain. I was told that tori are regular and that they did that kind of x-ray for all patients. So, my question for you is this what I am supposed to deal with for the rest of my life when I go to the dentist? Are there dentists who spare their tori patients from having to go through this? I am perfectly happy to get the old fashioned type of x-rays.
