I have been reading alot about new digital dental xrays, they seem to have less radiation exposure than the old film xrays. Should I be looking for a dentist with this technology? I seem to have many dental problems since my first surgery one involves my now very narrow larynx due to my neck dissection which makes me a difficult intabation and every procedure I have now seems to break a tooth which then requires another xray. Am I getting paranoid or is this a valid concern? Any opinions?
