Digital Radiography (Digital X-Rays)
Digital radiography, or digital X-ray, is the latest technology used in dentistry to take X-rays. Instead of traditional X-ray film, this method uses an electronic sensor that captures and stores images directly on a computer. These images can be viewed instantly and enlarged, making it easier for dentists to detect problems.

Why Are Dental X-Rays Important?
Dental X-rays are preventive and diagnostic tools that reveal issues not visible during a standard dental exam. They help dentists detect hidden dental conditions and create accurate treatment plans. Without X-rays, many problems may go unnoticed.
Dental X-rays may reveal:
- Abscesses or cysts
- Bone loss
- Cancerous and non-cancerous tumors
- Decay between teeth
- Developmental abnormalities
- Poor tooth and root positions
- Problems inside a tooth or below the gum line
Detecting and treating dental issues early can save time, money, unnecessary discomfort — and even your teeth!
Are Dental X-Rays Safe?
We are all exposed to natural radiation in our environment daily. Digital X-rays produce a much lower level of radiation than traditional X-rays. They are not only safer for patients, but also faster and more comfortable to take. Since they are captured electronically, there is no need for chemical development, which helps protect the environment.
Although considered very safe, dentists still take precautions to limit radiation exposure. These include:
- Taking only necessary X-rays
- Using protective lead apron shields
How Often Should Dental X-Rays Be Taken?
The frequency of dental X-rays depends on your individual needs, including dental and medical history, oral exam results, symptoms, age, and risk of disease.
- Full mouth series: Recommended for new patients; usually valid for 3–5 years.
- Bite-wing X-rays: Taken at check-up visits; usually once or twice a year to detect new problems.
