Dental calculus, commonly known as tartar, is a hardened deposit that forms on the teeth. It is composed of minerals, bacteria, and food debris. Minor calculus can be difficult to see with the naked eye, but it can be detected on x-rays. This is because calculus is denser than the surrounding tooth structure, and it appears as a white or opaque area on an x-ray. By identifying minor calculus on x-rays, dentists can diagnose and treat gum disease early on, before it becomes more serious.
X-rays are a valuable tool for dentists because they allow them to see inside the teeth and gums. This information can be used to diagnose a variety of dental problems, including tooth decay, gum disease, and abscesses. X-rays can also be used to monitor the progress of dental treatment and to evaluate the results of surgery.
