How do dental X-rays work?

xraysX-rays pass through your mouth during a dental exam, more X-rays are absorbed by the denser parts (such as teeth and bone) than by soft tissues (such as cheeks and gums) before striking the film. This creates an image on the radiograph. Teeth appear lighter because fewer X-rays penetrate to reach the film. Tooth decay, infections and signs of gum disease, including changes in the bone and ligaments holding teeth in place, appear darker because of more X-ray penetration. Dental restorations (fillings, crowns) may appear lighter or darker, depending on the type of material used for the restoration. The interpretation of these X-rays allows the dentist to safely and accurately detect hidden abnormalities.

How often should X-rays be taken?

How often X-rays (radiographs) should be taken depends on the patient´s individual health needs. It is important to recognize that just as each patient is different form the next, so should the scheduling of X-ray exams be individualized for each patient. We will review your history, examine your mouth and then decide whether you need radiographs and what type. If you are a new patient, Dr. Krause may recommend radiographs to determine the present status of the hidden areas of your mouth and to help analyze changes that may occur later. If you have had recent radiographs at your previous dentist, she may ask you to have the radiographs forwarded.

The schedule for needing radiographs at recall visits varies according to your age, risk for disease and signs and symptoms. Recent films may be needed to detect new cavities, or to determine the status of gum disease or for evaluation of growth and development. Children may need X-rays more often than adults. This is because their teeth and jaws are still developing and because their teeth are more likely to be affected by tooth decay than those of adults.

diagnodentDIAGNOdent – Laser Caries Detection Aid

More and more patients place value on healthy and attractive teeth. In order to maintain them, the earliest possible care is essential.

DIAGNOdent aids in the detections of caries. Even very small lesions are detected at the earliest stage, enabling you to protect and preserve the tooth substance.

intraoralcameraThe intraoral camera is a revolutionary diagnostic dental tool allowing us to more identify potential problems within the mouth early on. The tiny intraoral camera can be inserted into a patient´s mouth, taking pictures of the teeth and displaying the images on a computer screen.

Using the intraoral camera saves time and makes problems easily visible to both patient and doctor. Patients can view the areas we will be working on, making procedures more understandable. The accompanying software also provides clear and accurate data so that the best treatment options can be selected. To learn more about the intraoral camera, please contact our office today.


The VELscope is a handheld scope used to detect abnormalities. The scope can detect infections, inflammation, pre-cancerous cells and oral cancer. By using this type of technology, these abnormalities can be detected sooner, and early detection is key! The VELscope works by using tissue fluorescence visualization, or by illuminating the cells of the mouth. Our office utilizes the VELscope in our comprehensive exams making sure our patients receive the best possible care.
