Small X-Ray - Emergency Dentist London

Dental radiographs, are pictures of the teeth, bones, and surrounding. A radiographic image is formed by a controlled burst of X-ray radiation which penetrates oral structures at different levels, depending on varying anatomical densities, before striking the film or sensor.

Teeth appear lighter because less radiation penetrates them to reach the film. Dental caries, infections and other changes in the bone density, and the periodontal ligament, appear darker because X-rays readily penetrate these less dense structures. Dental restorations (fillings, crowns) may appear lighter or darker, depending on the density of the material.

A small x-ray can be used to determine how deep the caries in your teeth is, This way it can be decided if it will be necessary to perfor a root canal treatment or if the case can be solved with a filling at the first stage.
