Bitewing X-ray

A Bitewing X-ray is a small intraoral radiograph that shows the upper and lower teeth in one area of the mouth on a single image. It is especially useful for detecting interproximal (between-teeth) decay, assessing the fit and margins of fillings and crowns, and monitoring the height of the alveolar bone to screen for early signs of gum disease.

The procedure is quick and simple: the patient bites on a tab or holder that positions the sensor or film while the X-ray is taken. Radiation exposure is low, and dentists use bitewing images routinely to spot problems early so that conservative treatments such as fillings or periodontal care can be planned if necessary.
