Digital X-rays are a useful diagnostic tool when helping your dentist detect damage and disease not visible during a regular dental exam. How often X-rays should be taken depends on your present oral health, your age, your risk for disease, and any signs and symptoms of oral disease. For example, children may require X-rays more often than adults because their teeth and jaws are still developing and their teeth are more likely to be affected by tooth decay than those of adults.
If you are a new patient, the dentist may recommend X-rays to determine the present status of your oral health and have a baseline to help identify changes that may occur later. A new set of X-rays may be needed to help your dentist detect any new cavities, determine the status of your gum health or evaluate the growth and development of your teeth. If a previous dentist has any radiographs of you, your new dentist may ask you for copies of them. Ask both dentists to help you with forwarding your X-rays.
Digital radiography itself is similar to traditional X-rays with the exception that dental assistant inserts a digital sensor instead of traditional film into the patient’s mouth to capture image of his teeth. The sensor sends an image to the computer, to which it is connected. After seconds, image is projected on a screen for a doctor to view. Afterwards it is recorded and saved in your medical history file.
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 office. 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, and using lead apron shields to protect the body.
