A dentist may take X-rays of the mouth, jaw or specific teeth to look for specific problems, or to check on the general health of teeth.
Once the xray is take, the dentist will then be able to look at the X-rays on a screen straight after the images are taken.
There are two types of intraoral X-rays that we take.
Each of these X-rays shows different aspects of teeth.
- Bite-wing X-rays show details of the upper and lower teeth in one area of the mouth. Each bite-wing shows a tooth from its crown to about the level of the supporting bone. Bite-wing X-rays are used to detect decay between teeth and changes in bone density caused by gum disease. They are also useful in determining the proper fit of a crown (or cast restoration) and the soundness (marginal integrity) of fillings.
- Periapical X-rays show the whole tooth - from the crown to beyond the end of the root to where the tooth is anchored in the jaw. Each periapical X-ray shows this full tooth dimension and includes all the teeth in one portion of either the upper or lower jaw. Periapical X-rays are used to detect any abnormalities of the root structure and surrounding bone structure.
- Extraoral X-Rays
- Panoramic X-rays (Panorex) show the entire mouth area - all the teeth in both the upper and lower jaws - on a single X-ray. This type of X-ray is useful for detecting the position of fully emerged as well as emerging teeth, can identify impacted teeth, and aid in the diagnosis of tumours.
