Are Dental X-Rays Safe?

 We all have had the experience of having an x-ray done at least once in our lifetime. X-ray is the diagnostic tool that is usually used to diagnose an underlying condition in our bodies. The same goes with dental x-ray. Whenever you want to visit a dentist, and you search for clove dental near me or any other clinic, the dentist might suggest an X-Ray to check the condition of your mouth. Dental X-rays, also known as radiographs, are images of your teeth that help in precise diagnosis and treatment planning. But many of us have many misconceptions and myths regarding dental X-rays like they emit harmful rays, exposure to dental X-rays is very high, or too many dental X-rays may cause brain tumours. But as per many scientists and professionals, dental X-rays are one of the safest and most reliable imaging techniques used in today's scenarios. The radiation emitted during a dental radiograph is far less than what we experience in our daily lives. Let us know more about it in detail. 



How do dental X-rays work

Dental X-rays are used to diagnose the condition of the tooth present below the gum line. They are short outbursts of electromagnetic radiation that capture bodily tissues' images. Different X-rays are used for different conditions depending on different physiological factors. The most commonly used dental X-rays are the bitewing type of radiograph. A dentist or a dental hygienist are trained professionals and use all the safety measures while taking an x-ray. Protective lead aprons are worn, rearrange exposure settings, manage short exposure times, etc. All who have been under this situation will know that they are quick, painless, and non-invasive.  



Amount of radiation in a dental Xray

Dental X-rays also use radiation for detection, but they are perfectly safe as the exposure levels are significantly low. According to the U.S Nuclear Regulatory Commission(NRC), a person exposes themselves to 620 millirems of radiation every year, in which half of the radiation is from natural sources. 

The normal amount of radiation from a single dental digital x-ray is about 0.1 millirems. This radiation exposure is less than half the amount of radiation an individual receives throughout the year from different environmental sources. Like natural radiation from soil which is 35 millirems per year, or smoking cigarettes that are 1,300 millirems per year or from aircraft that is 2-4 millirems. Even drinking water and use of natural gasses also expose you to a certain amount of radiation. Dental X-rays and techniques are designed in such a way to expose an individual to minimum radiation. The radiation exposure received from a dental x-ray is less than half the amount of radiation an individual receives throughout the year.



Who needs a dental X-ray?

Dental radiographs are a key tool for precise diagnosis and proper treatment planning. A tooth covered with different layers. Each layer has its importance. And dental x-rays help us to diagnose the condition of each layer. They are used to diagnose the root cause of the pain. They help us to diagnose

  •  Decay between the teeth.

  •  Any changes in the tooth root.

  •  If the infection has reached the root canals. 

  • Any changes in the bone holding the tooth.

  • Checking for bone loss. 

  • Any tumours or growths if developed. 

  • Infections of bone or gums etc. 

These conditions should be diagnosed as soon as possible when suspected. Dental x-rays help as a major helping tool in its diagnosis. If there is any delay in its diagnosis, it may lead to worse conditions and complications. But pregnant women are an exception to this. In pregnancy, any x-ray is contraindicated. 



Regular dental checkups are a must, and getting a dental x-ray done is safe. Initially, when the x-rays were developed, professionals were less experienced and lacked proper knowledge. But with the advancement in technology, they are proved to be safe and harmless. Don't be afraid, and get your dental checkup done now.
