Why do we need to take x-rays? Is taking an x-ray safe?
It may be a concern for you that too many x-rays are taken so you end up glowing in the dark. In dentistry, the most common radiographs are of very low radiation dose. Some dentists don't even bother to leave the room when they're taken.
The point of radiographs is to be able to see what we cannot see with normal vision. We can see through objects like bone and gums.
What are x-rays?
An x-ray, is a kind of high energy radiation, called electromagnetic waves. The x-ray beams can go through the body and makes it possible to create pictures showing the internal body structures. The picture can either be printed on special film or viewed on a computer. We take dental x-rays to check teeth and mouth.
Is there radiation exposure?
There is radiation exposure, in fact, we are actually exposed to radiation everyday. There is natural radiation that comes from different things – it will from the food we taking, the air we breathing, even from the ground. Every single dental x-ray we receive as well as other medical image tests will adds an additional dose to our exposure to radiation.
This additional dose level varies depending on the medical examination we receive. Dental x-ray usually have very small radiation dose while exams involving higher extensive use of x-rays will have greater radiation doses, an example such as CT scans.
While we adding the dose of our exposure to radiation does this mean that we are increasing our risks of radiation?
The radiation dose involved in x-ray tests are too low to cause any influence or immediate unpredictable effects. Technically it would increase the risk. But it is a very low risk. Just like how technically jumping gets you closer to the stars in the sky.
