Small cavities on the surface of teeth that can be seen with the naked eye during dental treatment may be part of it. Severe cases of cavities often go deep into the teeth. 'Tooth X-ray' is designed to be small so that it can be taken inside the oral cavity instead of from the outside, and it is designed to facilitate more precise examination and not cause wounds in the oral cavity with soft edges.
The tooth X-ray is designed to be round so as not to damage the gums inside the teeth, and some parts need to be fixed by pressing by hand, so the area that is pressed by the hand is lined with an intaglio angle so that it can be closely attached to the gums. It is designed in a shape and size suitable for this because it will be used to take pictures of the inside of teeth in various ways, not a one-time use product.
