It is my opinion that the new digital x-rays are safer, because the x-rays taken by your dentist will have less radiation.
Probably, meaning less chance of head and neck cancer. Not to mention, the digital x-rays of your teeth and gums can be blown up very large on a computer screen, helping the hygienist and dental staff to better diagnose your cavities and other problems.
So basically one could argue that the digital x-rays could reduce your chance of getting cancer and reduce your chance of needing crowns, root canals, and filling through early detection. Just something to think about, and just my personal opinion. Click here for more information
