Like brushing and flossing, getting regular dental X-rays is an integral part of your overall oral health  Dental X-rays  are images of your teeth that your dentist uses to evaluate your oral health. These X-rays are used with very low levels of radiation to capture images of the interior of your teeth and gums. This can help your dentist to identify problems, like cavities, tooth decay, and impacted teeth and treat you accordingly.Dental X-rays are typically performed yearly but can be more often if your dentist is tracking the progress of a dental problem or treatment.
