Prevent Oral Ailments with Dental Radiography

We often associate X-rays with broken bones, and because of this we think of them as being part of diagnostic rather than preventative medicine. In dentistry, however, it’s different. Dental X-rays play an invaluable role in detecting problems before they become major and are an important tool that we use to judge the progress of ailments.

You’re familiar with the lead vest and being asked to bite down on various shaped pieces of plastic. If you’ve ever wondered what these methods are, here is a rundown of each type of dental X-ray and what each accomplishes:

Intraoral

Bite-wing 

Dental Radiography - intraoral - bite-wing

  • Gives us a view of in between the back teeth – molars and bicuspids
  • Assess the health of bone surrounding the teeth
  • Used to see cavities

Periapical

  • Gives a detailed picture of an entire tooth from root to crown and the surrounding bone
  • Used to check for infection (abscess)

Occlusal

  • Used frequently in children to view tooth development and placement
  • Bird’s eye view showing all of the lower or upper teeth and jaw

 

Extraoral

Panoramic

Dental radiography - extraoral - panoramic x-ray

  • Taken from outside the mouth, they show the teeth, jawbones, and skull
  • One image that shows the entire mouth
  • This is accomplished by a special machine that moves in a full rotation around your head
  • A ‘landscape’ image which shows more anatomical structures than other X-ray techniques

Cephalometric

  • An image of the entire side of the head
  • Used frequently by orthodontists to assess the position of teeth relative to the skull

CBCT (Cone Beam)

  • 3-D image that can be used to evaluate hard and soft tissue prior to treatment

 

Various X-ray techniques are important for catching many dental ailments before they get worse, such as cavities or gum disease. We recommend having bite-wing x-rays once a year for general maintenance. If more complicated treatment is needed, then different x-rays may be needed.  If it’s time for you to have new X-rays, give us a call at 207-781-5900 to make an appointment.

How Frequently Do You Need Dental X-Rays?

When we think of dental tools, the first things that come to mind are molds, drills, and scrapers. But the often-overlooked dental X-ray is one of the most important tools in the dentist’s arsenal for maintaining oral health. Since dental X-rays are used to diagnose problems, they are often the first line of defense for dentists to assess what ailments a new patient may have. But dental X-rays are not just for new patients.

Adults with healthy teeth should be getting X-rays of their teeth every 2 to 3 years. Children, however, should have X-rays taken every year since their teeth are constantly growing, which causes rapid changes. As with most everything else, the sooner a problem is detected the easier, and cheaper, it will be to correct and dental X-rays play a huge part in fixing oral health problems. When is the last time you had X-rays of your teeth taken? Call our office today at 207-781-5900 to make your appointment.
