Doctors and dentists study the use of x-rays and know how to set limits for their safety. At times, dentists take x-rays in order to diagnose a particular problem.
Improvements in technology mean that today’s digital x-rays release much less radiation and are allot safer in comparison to x-ray technology in the past.
You can expect to have an x-ray taken if you haven’t seen the dentist in a while and also if you visit the dentist with a painful tooth.
