Before you get the dental treatment, the dentist may ask you to sit in front of the dental x-ray sensor and take an x-ray of your teeth. Like the dental unit, the dental x-ray also is one of the most important pieces of dental equipment. But, most people worry about the safety of the dental x-ray. To ease your anxiety, this post would cover the frequently asked questions about dental x-ray.
Generally speaking, like endoscope system, x rays are capable of directly showing you if you have any decay under the enamel, any possible infections in the root, or any bone loss around the tooth.
Although dental x rays can show the infection of the root or root, it is not able to show decay that may not be seen directly in the mouth. In children, the x-ray is able to show any teeth that haven't come through yet, and show dentists whether there is enough space for the teeth to come through.

The dental x-ray is an advanced technology for diagnosing problems in patients' teeth and jaws. As a form of high-energy electromagnetic radiation, x-rays are capable of penetrating the body to form an image on film or screen.
During the process, the dense structures such as silver fillings or metal restoration, etc would block most of the light energy from the x-ray, which makes the dense structure appear white in the image. As for the structures that contain air, they will be black in the image, and teeth, tissue, and fluid will appear as shades of gray.
The normal dental x-ray typically has a wavelength ranging from 10 picometers to 10 nanometers. In other words, it corresponds to frequencies in the range 30 petahertz to 30 exahertz (30×1015 Hz to 30×1018 Hz) and energies in the range 145 eV to 124 keV. But it also depends on the types of dental x ray which includes One has intra oral camera, the other one has extraoral camera.
The American Dental Association recommends that the healthy adult who has no frequent or apparent dental problems just needs to take an x-rays exam every 2-3 years. Those who always suffer from dental problems, need X-rays taken once or twice a year.
Based on a new study, those who are repeatedly exposed to the X-rays may increase their risk of thyroid cancer and tumors in the tissue that covers the brain and spinal cord.
Because the dentist may take hundreds of x-rays every week, they have to limit the received amount of radiation by moving away from the x-ray beam, so as to reduce the potential health risks. However, the risk to patients from one or two routine x-rays is little.
Although the amount of radiation offered by the X-ray is very low, and American Dental Association and the American Pregnancy Association indicated that the amount of radiation in X-ray is not enough to cause any harm to a pregnant woman or her baby, you still need to illustrate your body situation to let your dentist know whether you are pregnant before you get the dental treatment. The dentist would take the extra care and will probably not use x-rays unless they really have to, especially during the first three months.
All in all, in medical, dental x-ray and portable x-ray play an important role in surgical. A reliable and advanced dental x-ray helps a lot with dentists. It helps dentists see in between patients' teeth or under the edge of their fillings. Finding and treating dental problems at an early stage can save patients both time and money.
