Dental X-Rays: How Do They Work?

Dental X-rays or radiographs are an important part of any dental care treatment plan.

These X-rays have been around as long as those infamous grinding drills we used to endure with tears streaming from our eyes. Dental X-rays are diagnostic as well as preventative. Dentists are able to diagnose potential dental problems before they become a major issue.

Dental X-rays were a wonderful breakthrough helping dentists to pinpoint countless cavities and provide the appropriate treatment.

How do dental X-rays work?

When an X-ray passes through the mouth, teeth and bones absorb the rays far more than the surrounding gums and soft tissues.

As a result, teeth appeared lighter on the X-ray image while any cavity, decay or infection shows up as darker spots.

Are dental X-rays harmful?

They certainly used to be, even if it was only slightly harmful. The machines used for dental X-rays do involve radiation but the amount of exposure is extremely small. However, small doses over time can add up to cell damage which is why experts recommend the usage of X-rays should be limited and taken only when necessary. Talk to your dentist about how often you or your children need X-rays and why.

Why are dental X-rays not as harmful now?

Digital technology has been the main reason for this factor. Several changes over the years have reduced the dental X-rays radiation exposure over the years:

• Lower X-ray dose that limits the rays to an area less than three inches in diameter
• Better film with fastest speed film that limit the amount of radiation needed to obtain a good picture
• Use of digital X-rays that reduces radiation by as much as 80%
• Making use of lead-lined full-body apron that covers you from the neck to the knees
• Limited use of X-rays.

Digital X-rays are 80 percent lower in radiation levels than the old x-rays. Digital X-rays are now the go-to form of X-ray for you and for dentists and they’re the next best thing to completely safe, while quickly highlighting decay or any other major issues in your mouth.

Dental X-rays digital vs traditional

Whereas traditional X-rays used harsh plates that cut into our gums, digital X-rays are taken with a small sensor. This small probe is moved around the mouth with ease and can take any number of images very quickly. These images are then instantly available on a computer monitor – therefore, no more waiting for those old X-rays to develop.

What’s more, they’re high-resolution digital images ensuring every last little abnormality in our mouths is spotted and dealt with.
