Dental X-rays are a diagnostic tool that your dentist uses to detect damage that’s not visible during a regular dental exam. Digital dental x-rays use digital sensors connected to a computer instead of traditional film. Once the image is taken, it’s transmitted to the computer where the dentist can instantly see it. This means you spend a lot less time sitting in the chair, waiting for the results of an x-ray. Also, digital radiography emits 90% less radiation than conventional x-rays.
Intraoral X-rays are the most common type of dental X-ray your dentist uses. These X-rays allow your dentist to find cavities between your teeth, check the health of your jaw and monitor the general health of your teeth and jawbone. When you come in for your first appointment, the dentist will most likely take an x-ray to determine the present state of your oral health and discover any existing conditions. After that, x-rays will be taken as needed depending on the oral health concerns that you have. Children may require x-rays more often since their teeth and jaws are still developing, and to check for childhood cavities.
