As mentioned previously, bitewing radiography allows accessibility to surfaces that may not be seen in the clinical visual–tactile examination, and it allows the depth of lesions to be assessed. Other advantages are that it is not invasive and does not damage tooth structure like an incorrectly used dental probe might. Radiographs can also be filed and reexamined at a later date to compare with a more recent image to detect whether a lesion is progressing or not.2
