Routine dental X-rays are not backed by evidence

And why is dental insurance in the USA picking up the bill? I haven’t directly paid my dentist for these annual exams in quite a long time.

The X-rays I can probably avoid the next time, but I feel the cleanings do really help. I used to have bad plaque build up on my incisors but keeping up with the cleanings and improving flossing technique keeps it at bay.
