Bitewings help detect cavities between teeth and bone loss. In short: review; place; position, then complete the remaining steps below.
Step by step
Review when the patient last had X-rays and confirm the dentist’s order.
Place a lead apron with thyroid collar if your office policy requires it.
Position the sensor in the holder behind the premolars or molars.
Ask the patient to bite gently on the tab or holder.
Align the cone with the sensor so the beam is perpendicular and passes between the contacts.
Expose, check the image for overlap and cone cuts, and retake only if necessary.
