An x-ray (also called a radiograph) is a type of light energy that bypasses soft tissue and soaks up the light of dense tissue. So a dental x-ray could pass through your cheeks and gums, but absorb your teeth, taking a sort of picture of them. X-ray machines do use radiation, but it is so light that it is not a danger to you.

The benefits can be immeasurably helpful in diagnosis, prevention, and preparation for dental procedures. X-rays help Dr. Chi find cavities, examine tooth roots, check the progress of periodontal disease, see how teeth are growing, prepare patients for restorative procedures, and perform other valuable jobs.

Ultimately, it depends on the needs of the patient, but here are some common examples:

• Periapical: Shows a comprehensive view of a single tooth, from jawbone to root to crown.
• Bitewing: Provides a side view of the bite, including the upper and lower arches and how they connect
• Panoramic: Offers an extensive view of the whole mouth area, including the teeth, jaw, nasal area, sinuses, and jaw joints.
• Occlusal: Allows the observation of teeth that are still below the gum line
