How are X-rays used in dentistry?

X-rays are used in dentistry to diagnose and treat dental problems.

X-rays, also known as radiographs, are a type of electromagnetic radiation that can penetrate through soft tissue and bone. In dentistry, X-rays are used to detect dental problems such as cavities, gum disease, and impacted teeth. They can also be used to monitor the development of teeth and jawbones in children.

To take an X-ray, a dentist will place a small film or digital sensor inside the patient's mouth and direct the X-ray machine towards the area of interest. The X-rays will pass through the patient's teeth and bones and create an image on the film or sensor. This image can then be analysed by the dentist to identify any dental problems.

X-rays are an important tool in dentistry because they can detect dental problems that may not be visible during a routine dental exam. They can also help dentists plan treatments such as fillings, root canals, and orthodontic procedures. However, X-rays do expose patients to a small amount of radiation, so dentists will only take X-rays when necessary and will use protective measures such as lead aprons and thyroid collars to minimise radiation exposure.

Overall, X-rays are a valuable tool in dentistry that help dentists diagnose and treat dental problems.
