They provide a picture of your teeth
The check-up x-rays allow your dentist to examine your teeth underneath the gum. Without this picture, the dentist can only see a third of your teeth. If there are any underlying conditions in the root and middle part of your teeth, only an x-ray can show this. The conditions that the x-ray will point out include cavities, impacted teeth, and tooth decay. They are able to show abscesses and any other problem that is beneath your gum. From the image, the dentist can know which treatment plan to follow that will provide the solution to your dental issue.
They come in various types
The various types of x-rays will give a different image of your teeth. Each type serves a different function and it helps to diagnose different conditions. Some such as bitewing seeks for interdental cavities by looking at how the crowns line up. Others offer a full picture of the teeth while others help in identifying problems that go beyond the teeth to cover the jaw and palate. The type you get will depend on what the dentist wants to find out about your teeth.
They are low risk
The x-rays use a low emission of radiation making them safe to use. Thanks to new technology, they have become safer and the results come in after a short while. You, therefore, do not have to worry about the health risks involved in getting such an intimate x-ray shot off your mouth. The risk becomes even lower when the dentist protects other parts of the body from the radiation. You will have peace of mind as you get the procedure done. In any case, the exposure is minimal as it does not take a long time to get it done.
They need not be frequent
The frequency of the x-rays will depend on their necessity. However, for adults that do not have any issues with the teeth, once a year is enough. Growing children and those on a treatment plan require more frequent x-rays. Children’s teeth are growing and it is important to check whether they are growing right. The x-rays will help to do this. If you are under a treatment plan, occasional x-rays will point out the effectiveness of the treatment.
