Are Dental X-Rays Safe?
January 8, 2015
Dental x-rays are used by a Summerville SC dentist dentist to help them find problems with their patients teeth, including bening masses, bone loss, cavities, or problems with teeth that have not yet grown in, in the case of children.
The x-ray works just like a traditional bone x-ray, penetrating the gum and showing the jawbone and the teeth. Teeth appear lighter on the x-ray immage than anything else in the area because less radiation can pass through them to reach the film. Low areas of bone density, and areas that are infected or that have caries or cavities appear darker because the x-rays can easily penetrate these areas since they are less dense. Fillings, crowns, caps and other pieces of dental work are usually easy to identify; being either much lighter or much darker than the nearby tooth.
Most dentists will only recommend dental x-rays in cases where there is a clear medical benefit to using them, because of the radiation that the patient will be exposed to. In the main, dental x-rays are safe – the amount of radiation that a person is exposed to in an x-ray is just 0.150mSv, which is about the same as the amount that you would be exposed to if you took a cross-country flight in an airplane. The radiation is, admittedly, concentrated into one small burst but it is unlikely to be harmful. As long as a patient is only getting a couple of x-rays per year, the cumulative effect of the exposure to radiation should be minimal. The potential benefit to be had from early detection of, and treatment of, any dental problems that the dentist is investigating is huge, and for this reason it is a good idea to accept an x-ray if the dentist suggests that one may be necessary.
