Educational Information on Dental X-rays

Intraoral are those which are taken inside the mouth whereas the extraoral x-rays are taken outside of the mouth. However, the intraoral x-rays are believed to be the most significant ones as they provide specifics regarding the tooth, the bone as the supporting tissues as well. They not only help the dentist in finding the cavities but also enable him to have a look at the tooth roots, to check the health of the bone area surrounding the teeth and to analyze the status of the developing teeth. 

How to Prepare for the Dental X-rays

Then, the X-ray machine is positioned on the side of the head to click the images of one’s mouth.

In some states, there also exist strict protocols for protecting the public’s safety. It is for these reasons, the procedure of dental x-rays is considered highly safe. Rather than taking multiple images, dentists prefer to take a single shot to decrease the exposure. Also, there are leaded coverings which can protect the various body parts from radiation.
