Sometimes We Need X-ray Vision

In today’s dental world it’s pretty common to have X-rays taken. Some dentists recommend X-rays every year so they can check for changes. There are two main types of X-rays; Intraoral and Extraoral. Your local dentist westborough may have taken one or both types of X-rays at one of your appointments. X-rays are an affordable way to ensure your teeth and mouth are the healthiest they can be. 

Intraoral X-rays

This type of X-ray is the most commonly used at your local dental office. They provide extensive details on the teeth roots, the bone structure surrounding the teeth, condition of teeth that have not yet developed, health of the jaw bone and they also show cavities. 

Three Types of Intraoral X-rays;

  • Bite-wing X-rays – These types of X-rays shows pictures of the upper and lower teeth in segregated areas of the mouth. On these X-rays you can see each tooth from the crown to the bone. These X-rays can detect differences in bone density potentially caused by gum disease. They can show decay between teeth. 
  • Periapical X-rays – This type of X-ray gives the dentist a look at the entire tooth. From the crown to the point where the tooth is attached to the jaw. The dentist can also see teeth in one area of the mouth on either the upper or lower jaw. Periapical X-rays show the root and bone structure and can identify anything abnormal. 
  • Occlusal X-rays- These X-rays are larger than Bite-wing X-rays or Periapical X-rays. They show the placement of each tooth in the upper or lower jaw with a shot of the all of the teeth. 

Extraoral X-rays

The main objective in this type of X-ray is showing the jaw and skull. These X-rays are used to detect abnormalities between the teeth and the jaws. Conditions like joint disorders can be detected. These types of X-rays are not as common at your local dental clinic as Intraoral X-rays. 

Types of Extraoral X-rays;

  • Panoramic – Shows all teeth in upper and lower mouth on one X-ray.
  • Tomograms – Shows only a layer of the mouth. 
  • Cephalometric – Shows one side of the head.
  • Sialography – Shows the salivary glands.
  • Computed Tomography – This is essentially a CT scan that shows the interior of a body in three-dimension.  

Your dentist will choose the type of X-ray that works best for your dental situation.
