What areas are intended to be shown by a bitewing x-ray?

Bitewing x-rays are specifically designed to capture the interproximal areas of the teeth, which are the spaces between adjacent teeth. This type of radiograph is particularly useful for detecting dental caries (cavities) that may not be visible during a clinical examination. The film is positioned in a way that allows both the upper and lower teeth to be imaged simultaneously, making it easier for dental professionals to assess the health of the interproximal surfaces.

By focusing on the interproximal region, bitewing x-rays help identify decay early, monitor existing restorations, and aid in overall treatment planning. This makes them an essential component of routine dental examinations, especially for patients who may be at higher risk for dental caries.
