Types of Dental X-rays, Their Importance, and Problems They Detect

Oct 06, 2021

Dental X-rays are those images of your teeth used by your dentist to evaluate your oral health. Low levels of radiation are used with x-rays to get images of the interior of your teeth and gums. They help the dentist to detect problems that are not visible with the bare eyes. These are problems like tooth decay, cavities, and impacted teeth. This article will discuss the importance of performing dental x-rays, their types, and the problems that they detect. Read on.

Importance of Dental X-rays

Dental x-rays help the dentist to treat your oral problem before it becomes more severe. This benefits you by saving money and discomfort in your mouth, especially when eating. It helps your dentist get a clear view of your oral health. Children are supposed to visit their dentist more regularly for dental x-rays. This will help the dentist to monitor the growth of their teeth. The dentist will pull the baby teeth where necessary to give room for the adult teeth to grow. By visiting our Ballard Family Dental dentist, you will get highly qualified x-rays on your mouth and get the best oral treatment services.

Problems Detected by Dental X-rays

Dental X-rays show problems in adults as well as in children. If you have any dental problems, visit a dentist near you to get a dental x-ray.

In adults, they detect problems like:

  • Dental abscesses. This is an infection found at the root of a tooth. An untreated cavity or an injury causes it.
  • It reveals an early decay at the surface of a filling
  • Exposing changes in the root canal that are caused by an infection.
  • It detects dental bone loss. This occurs when the bone that supports your teeth reduces because of an oral infection, causing teeth to become loose.

In children, it is used to:

  • Check if primary teeth will be lost early to give room for permanent teeth to grow
  • Show if there is enough space to fit all the teeth
  • Detect decay.

Types of Dental X-ray

There are many types of dental x-rays. However, there are five major dental x-ray types. These are:

  • Bitewing X-rays:

A digital x-ray is positioned in the mouth by a dentist during a checkup. They give details of a specific area in the mouth, that is, the upper and the lower area of the teeth. During the dental appointment, your dentist might take one or more bitewing samples. Each bitewing shows a tooth from its crown to the level of the supporting bone. They reveal any occurring decay between the teeth. Your dentist will detect bone thickness changes usually caused by gum disease. The dental expert will ask you to bite a little box wrapped in plastic.

  • Full mouth survey X-rays:

It has a series of individual images and a combination of bitewing and periapical x-rays. Our dentist in Ballard, Seattle, will use these images as a baseline on the health of your mouth. A full mouth x-ray is taken when you’re on your first appointment and also when your dentist suspects you have a jaw tumor.

  • Periapical X-ray:

They give an image of the whole teeth, from the chewing surface to the root where the tooth attaches into the jaw. Each periapical x-ray is used to detect any abnormalities of the root and surrounding bone structure. Your dentist will place a film with a ring attached to it near your mouth. Your dentist will then request you to bite the device firmly to keep it in place and provide a clear x-ray image.

  • Panoramic X-rays:

It is a two-dimensional dental x-ray that takes images of the entire mouth area. This x-ray gives the details of the position of teeth and the bones.

  • Occlusal X-rays:

They are used to show both the floor and the roof of the mouth and track a tooth that has not yet broken through the jaw or the gums. They can also be used in finding a foreign object.

Are Dental X-rays Safe?

According to our dentist in Cordova, dental x-rays are safe. The amount of radiation that a patient is exposed to is usually in low amounts. They are safe for both adults and children. A dental x-ray is also beneficial for diagnostic purposes.
