A bitewing exposure is a special x-ray of the teeth.

Bitewing Exposure

Bitewing Exposure

With a bitewing exposure a small piece of x-ray film is held in the mouth by means of a special device onto which the patient bites.

It enables an exposure to be taken of the side-teeth of the upper and lower jaws and of the crown area all at the same time and in addition there is no masking of teeth by other teeth. The main purpose of bitewing exposures is to locate caries in the contact areas of the teeth and beneath fillings. Caries can usually be seen in a bitewing exposure as long as they are still in the enamel. Furthermore you get a view of the periodontal situation, of the overlying crown and/or filling edges and of any accretions.
