Dental x-rays are important for detecting potential dental problems, gum disease, and osteoporosis. There are two types of dental radiographs: bite wing and periapical. Routine dental x-rays are recommended for children to detect cavities and impacted teeth. X-rays require low-level radiation exposure but are considered safe and only done at routine intervals or when a problem is suspected.
Dental x-rays are an important part of routine dental care for both adults and children. Not only do dental x-rays reveal potential problems with the oncoming teeth, they can also reveal potential problems caused by hidden plaque. In addition to detecting common problems with your teeth, dental x-rays can help detect gum disease and even osteoporosis.
There are two different types of dental radiographs: bite wing and periapical. The bite wing radiograph is taken when the teeth bite together and shows the crown portions of the upper and lower teeth. The periapical is a more selective radiograph done to show one or two specific teeth from the crown to the root.
In children, routine dental x-rays are recommended because they show the location, number and size of teeth and because they can detect the presence of cavities before they can be seen on the surface of the teeth. Without dental x-rays, a dentist must rely only on a visual examination of the teeth. Sometimes cavities begin to form from plaque lodged between teeth where a dentist cannot see. With the help of dental x-rays, hidden cavities can be detected and treated early so that there is less damage to the tooth.
Routine dental x-rays also detect impacted teeth, which can be a problem from infancy to early adulthood. If you have an injury, dental x-rays help determine the type and extent of the injury. Recent research also indicates that dental X-rays could serve as an alternative method of screening for osteoporosis in the elderly.
Dental x-rays, like all other x-rays, require low-level radiation exposure, but are still considered safe and are only done at routine intervals or when a problem is suspected. Talk to your dentist if you have any questions or concerns about dental x-rays. Typically, you don’t need a special appointment for x-rays as they can be done as part of routine cleanings and exams.
