One of the technologies that has been long used in the industry and is still being used is dental x-rays. Even with the new and advanced technologies of today, people still wonder if x-rays are safe. This is because people have been aware that radiation is a danger to humans for nearly a century. Too much exposure to radiation can cause a myriad of health issues, including damaging the tissues and cells in the body and eventually causing cancer.
However, the dosage of radiation to which you are exposed when a dentist takes an x-ray of your mouth is very minimal, much lower than it was in the mid-20th century. Scientists and researchers have come a long way since then. The low radiation levels emitted by these x-rays are so limited there is virtually no chance of damage to the person. Additionally, the x-ray devices used today take the pictures at a much higher speed, there is a shorter exposure time, and the devices are made to be safer than they were before.
In addition to the short exposure time, you are also only exposed to x-rays once a year at the dentist. Your dentist needs to take bite-wing x-rays every year, and a full-mouth x-ray every three years.
Dental hygienists use full-body, lead-lined aprons to keep their bodies protected from radiation exposure. There are also additional measures being taken to keep people even safer. For instance, a leaded collar prevents those with thyroid issues from being exposed to radiation. These collars are also used for pregnant women, children and women of child-bearing age.
To top it all off, the federal government requires that all x-ray machines be checked for accuracy and safety at least every two years. If there is a chance of any trouble, the machine must be checked more often.
If you are still unsure about dental x-rays, ask your dentist for more information. If he has requested x-rays, you should ask any questions before the x-rays are taken so that you are secure and comfortable while the process is going on. The more relaxed you are, the smoother the procedure will go.
