Can you tell me what occurs if you forget to take out a piercing for a dental xray?

Distorted image: Some types of dental x-ray machines like a panorex takes a large film of the lower half of the face, teeth and jaws. This film will swing around the head exposing one side than the other. A metal object like a piercing, even an earring, can cause a shadow or distortion on film that can mask or hide important details. You can be misdiagnosed because of it.
