Dental X-rays are a valuable tool for dentists to detect and diagnose a wide range of dental problems. One of the things that dentists can see on X-rays is calculus, which is a hard, calcified deposit that forms on the teeth. Calculus is composed of plaque, bacteria, and minerals, and it can cause a number of problems, including gum disease, tooth decay, and bad breath.
Calculus is visible on X-rays because it is denser than the surrounding bone and tissue. This allows dentists to see the extent of the calculus buildup and determine the best course of treatment. In some cases, calculus can be removed with a simple cleaning, while in other cases, more extensive treatment may be necessary.
