X-rays, also called radiographs, give your dentist the ability to see between and inside your teeth. He can also view the tip of your roots and bone underneath your gums – places not normally visible to the naked eye. Although they are used as part of a routine examination to rule out dental disease, X-rays also aid your dentist in diagnosing any specific or isolated dental problems you might be experiencing.
Radiographs are used to check for cavities and evaluate the extent of decay. And because some X-rays show the root of the tooth, according to the Academy of General Dentistry (AGD), the presence of any cysts, abscesses and other masses can be diagnosed. Congenitally missing or impacted teeth such as wisdom teeth are often identified this way, and the presence and extent of bone loss due to periodontal disease is easily seen through dental X-rays as well.
