Digital Radiography (digital x-ray) is the latest technology used to take dental x-rays.
This technique uses an electronic sensor (instead of x-ray film) that captures and stores the digital image on a computer. This image can be instantly viewed and enlarged helping the dentist detect problems easier. Digital x-rays reduce radiation 80-90% compared to the already low exposure of traditional dental x-rays.
Dental x-rays are essential, preventative, diagnostic tools that provide valuable information not visible during a regular dental exam. Dentists use this information to safely and accurately detect hidden dental abnormalities and complete an accurate treatment plan. Without x-rays, problem areas may go undetected.
There are two main types of dental X-rays:
Intraoral (meaning the X-ray film is inside the mouth) and Extraoral (meaning the X-ray film is outside the mouth).
• Intraoral X-rays are the most common type of dental X-ray taken. These X-rays provide a lot of detail and allow your dentist to find cavities, check the health of the tooth, root and bone surrounding the tooth, check the status of developing teeth, and monitor the general health of your teeth and jawbone.
• Extraoral X-rays show teeth, but their main focus is the jaw and skull. These X-rays do not provide the detail found with intraoral X-rays and therefore are not used for detecting cavities or for identifying problems with individual teeth.
Instead, extraoral X-rays are used to look for impacted teeth, monitor growth and development of the jaws in relation to the teeth, and to identify potential problems between teeth and jaws and the temporomandibular joint or other bones of the face.
Dental x-rays may reveal:
- Abscesses or cysts
- Bone loss
- Cancerous and non-cancerous tumors
- Decay between the teeth
- Developmental abnormalities
- Poor tooth and root positions
- Problems inside a tooth or below the gum line
Detecting and treating dental problems at an early stage may save you time, money, unnecessary discomfort, and your teeth!
Are Dental x-rays safe?
We are all exposed to natural radiation in our environment. Digital x-rays produce a significantly lower level of radiation compared to traditional dental x-rays.
Not only are digital x-rays better for the health and safety of the patient, they are faster and more comfortable to take, which reduces your time in the dental practice. Also, since the digital image is captured electronically, there is no need to develop the x-rays, thus eliminating the disposal of harmful waste and chemicals into the environment.
Even though digital x-rays produce a low level of radiation and are considered very safe, dentists still take necessary precautions to limit the patient’s exposure to radiation. These precautions include only taking those x-rays that are necessary.
