Why have I been advised to have small X-rays if I already have an orthopantomography?
Ortopantolography is very valuable as an overall picture of all the anatomical structures of your mouth.
However, a quality intraoral X-ray allows you to reveal maximum detail of your teeth and the periodontium (ligament and bone) with optimal density and contrast.
