Dentists consider x-rays one of the most helpful tools in helping patients maintain good oral health. X-rays help dentists diagnose common disorders such as cavities, periodontal disease and infections, and some of the more uncommon problems, such as cysts, abscesses and tumors.
X-rays can also allow your dentist to determine whether a child's permanent teeth are erupting properly. In general, children need x-rays more often than adults because their mouths grow and change rapidly, and they are more susceptible to tooth decay than adults
An advance in x-ray technology is digital x-rays which uses sensors that feed the images to a computer.The digital x-ray system is more sensitive than the traditional dental x-ray film systems, so exposure to x-rays is cut by as much as 90 percent.
You are exposed to many sources of radiation every day, from the sun, your home appliances etc. Radiation can damage the body's tissues and cells and can lead to the development of cancer, but fortunately, the radiation to which you are exposed during the taking of digital x-rays is extremely small.
Without the ability to see inside a tooth and beneath the gums, some disease would go undetected and more teeth would be lost because needed treatment wasn't started in time. If dental problems are found and treated early, dental care is more comfortable and affordable. Digital x-rays are not without risk, but the risk is minuscule compared with the huge diagnostic benefit of keeping your natural teeth healthy and disease free.
