Dental X-Rays (Radiographs)
X-rays help your dentist see the jaw bone, the roots of the teeth, or teeth that have not yet erupted, as well as the contact areas between the teeth. In some cases, x-rays can reveal a condition at an early stage, when it is easier to treat.
Some Conditions X-Rays Can Help Detect:
• small areas of decay in the teeth or below fillings
• bone diseases
• abscesses or cysts
• signs of periodontal (gum) disease
• developmental and other defects
• some types of tumors
• positions of tooth roots and jaw bones
• signs of trauma
This X-ray shows decay between the teeth (interproximal decay). Sometimes occlusal decay can also be seen on a bitewing film.
(around the tooth’s root) This X-ray shows the crown of an impacted molar.
(upper or lower jaw) This X-ray shows an unerupted tooth.
CBCT (cone-beam computed tomography)
CBCT images can show more detail than X-rays.
Complete-mouth series of bitewing and periapical X-rays shows all of the teeth, roots and related areas of the jaws.
This X-ray shows developing permanent teeth that have not yet erupted.
