X-Rays

Dental x-rays are pictures of the teeth, bones, and surrounding soft tissues to screen for and help identify problems with the teeth, mouth, and jaw. X-ray pictures can show cavities, hidden dental structures (such as wisdom teeth), and bone loss that cannot be seen during a visual examination. Dental x-rays may also be done as follow-up after dental treatments. Many diseases of the teeth and surrounding tissues cannot be seen when your dentist examines your mouth. An x-ray examination may reveal:

• small areas of decay between the teeth or below existing restorations (fillings)
• infections in the bone
• periodontal (gum) disease
• abscesses or cysts
• developmental abnormalities
• some types of tumors

Finding and treating dental problems at an early stage can save time, money and unnecessary discomfort. It can detect damage to oral structures not visible during a regular exam. If you have a hidden tumor, radiographs may even help save your life.

Types of X-Rays

Periapical (PA): Periapical x-rays show the entire tooth, from the exposed crown to the end of the root and the bones that support the tooth. These x-rays are used to detect dental problems below the gum line or in the jaw, including the presence of impacted teeth.

Bitewing: Bitewing x-rays use the least amount of radiation and show the upper and lower back teeth in a single view. They are used to detect decay between the teeth and to show how well the upper and lower teeth line up. They also show bone loss that usually indicates the presence of severe gum disease or a dental infection.

Panoramic: Panoramic x-rays provide a broad view of the jaws, teeth, sinuses, nasal area, and temporomandibular (jaw) joints. These x-rays do not show the detail needed to detect cavities. These x-rays reveal problems such as impacted teeth, bone abnormalities, cysts, solid growths (tumors), infections, and fractures.
