Some dentists recommend removing wisdom teeth if they don't fully emerge. If wisdom teeth don't have enough room to come in properly, they may crowd or damage nearby teeth. Because this area is hard to see and clean, wisdom teeth that partially emerge create a passageway that can become a magnet for bacteria that cause gum disease and oral infection. Sometimes this can result in infection or can cause a cyst that can damage other teeth roots or bone support. If they aren't able to emerge normally, wisdom teeth become trapped (impacted) within your jaw. Remain completely hidden within the gums.Erupting wisdom teeth can grow at various angles in the jaw, sometimes even horizontally. They are often used to plan the sizing, placement and configuration of dental implants.Many times, however, wisdom teeth don't have room to grow properly and can cause problems. Cone beam scans are not a typical part of prevention or treatment, and therefore aren’t done on all patients. This scan information is then sent to a computer where special software helps generate a 3-D model of your teeth and jaws. Just like the panoramic, the patient stands or sits still while the sensor rotates around. It’s easiest to think of cone beam CT (computed tomography) as a 3-D version of a panoramic x-ray. For this reason, they are often used in diagnosing dental abscesses, which can be caused by infections or decay on the tooth root and are therefore not visible from the outside. Unlike bitewing x-rays, periapical x-rays look at the entire tooth, from crown to root. Periapical x-rays take a close look at just a few teeth at a time. Panoramic x-rays are used in orthodontic treatment planning, such as braces, and when planning extractions, including wisdom teeth removal. There are usually braces for your head and face that help keep you very still while the scanner revolves around you. The x-ray scanner itself then rotates from one side of your head to the other, creating a continuous image. Instead of being done in the dental chair, panoramic x-rays use a special machine that the patient stands in. They show the entire tooth, crown and root, plus the jawbone. Panoramic x-rays show your entire mouth in a single image, both top and bottom jaws (or arches, in dentist-speak). Bitewing x-rays can also be used to monitor wisdom teeth and help plan wisdom teeth removal. Most patients get bitewing x-rays about once a year, but patients who are prone to tooth decay may get them more often. These x-rays show just a few teeth at a time and are used primarily for detecting potential tooth decay between teeth that isn’t visible to the naked eye. They are called bitewing because the patient bites down on a wing-shaped sensor or film while the x-ray machine takes the image. These are the type of x-rays patients are the most familiar with. In the last 122 years, dental x-rays have been continuously improved to be safer, gentler, & more accurate. The first dental x-ray was taken just 14 days after the discovery was announced. He called them x-rays because he didn’t know what they were, hence the “x”, and the name stuck. A German scientist named Wilhelm Conrad Roentgen discovered x-rays in 1895. There are several different types of dental x-rays, and it’s a good idea to know what each one is for so you’ll understand why we take so many!ĭental x-rays have been in use for a long time. They allow us to see potential threats to you dental health (like cavities) & plan treatment more accurately. Dental radiographs, commonly known as dental x-rays, are one of the dentist’s most powerful preventive & diagnostic tools.
