Digital x-rays?

It has been at least 18 months since I had been in for a cleaning.  So maybe this isn't news to everyone, but my dentist used a digital x-ray machine today.

Digital x-rays have half the exposure but they make it up by taking twice as many shots. Which means it is really the same.

Digital X-ray and Sensor

No waiting for the film to be processed.  They put a small device/sensor in your mouth. (It is wrapped in a plastic disposable sleeve.) They line up the camera and snap the picture.  Then they glance at the computer to make sure it turned out the way they want it to.

Pretty cool, huh? It makes you think, "What's next? "

I changed my diet about 18 months ago. This is the first time that I've been to the dentist without needing to have a cavity filled or without getting warned about receding gums.  It appears  (in an unscientific study of 1) that my diet change has been good for my teeth!
