A General Dentistry Explains the Uses for X-rays

X-rays are used not only in medical offices but in general dentistry offices as well. This type of assessment is often performed at least once a year at dental checkups, and more often for some patients. While it may seem like a simple step at your biannual appointment, it can be critical for maintaining healthy teeth and gums.

Important uses of dental X-rays

Dental professionals can use a variety of methods to detect and diagnose dental issues:

• Visual examinations
• Discussion of symptoms
• Assessment of affected tissues with dental tools

However, some problems may not be detectable by the naked eye. Others do not demonstrate symptoms above the surface until they have progressed and become serious. X-rays help dentists get a good look at the underlying tissues to properly monitor dental health.

Checking for proper growth and development

X-rays help dentists see that a child's teeth and bones are growing as expected. When abnormalities are detected, dentists can begin treatments at an early age to help prevent speech and digestive issues, as well as facial deformities.

Monitoring existing conditions

People with minor decay, gum disease, or bone loss may receive X-rays more often to monitor these conditions. In some situations, treatment may not be necessary unless the issues show signs of progressing.

Detecting serious dental problems early

While oral cancer is not highly common, it often goes undetected until troublesome symptoms arise. This can limit treatment options or lead to a less favorable outcome for the patient. X-rays can help dentists see the signs of serious issues long before symptoms arise, including tumors and growths, bone deterioration, and some types of infection and decay.

Recognition of X-ray radiation and safety

X-rays expose patients to minor amounts of radiation to obtain detailed images below the surface. While it is important to limit radiation exposure whenever possible, the amount received during a dental X-ray is so small and infrequent that it is not a concern for most normal, healthy patients. In fact, you can be exposed to more radiation when flying in an airplane or from eating certain foods on a regular basis. Refusing to get an X-ray could be more harmful long-term for many people.

General dentistry X-rays are used for patients of all ages, including young children. However, most dentists limit their use in those who are low-risk for certain complications, especially kids. They may be necessary more often for those who have a history of decay or need monitoring for dental issues. In general, dental X-rays are not performed on pregnant women or those who are undergoing certain types of medical treatment.
