Bitewing X-rays

Bitewing X-rays are one of the most common X-rays taken in dental offices and are used to detect cavities by showing decay in between teeth and under restorations, show bone loss when severe gum disease or a dental infection is present, and locate worn out fillings. This view is taken at a perpendicular angle to the side of your teeth to visualize the crowns of the posterior teeth (bicuspids and molars) and the height of the alveolar bone in relation to the demarcation lines on the teeth which separate tooth crown from tooth root, which are called cementoenamel junctions.

During a bitewing X-ray, a small piece of X-ray film is placed inside your mouth and carefully positioned. When you bite down on the side tab of the packet, the film becomes properly aligned to get an even picture of your upper and lower teeth at the same time.

Your dentist may recommend bitewing X-rays as part of your routine dental checkup, typically once a year or as needed, to help maintain oral health.
