Dental X-Ray's

Dental X-Ray'sDental x-rays are taken by our dental professionals to aid the detection of tooth decay, gum disease, infections and other dental diseases. Most of these problems are difficult or even impossible to detect without the help of an x-ray. X-rays are a safe and powerful tool used to ensure your oral health. The x-rays pass through the area being examined to a sensor or sheet of film where the high energy rays project the image.

Intraoral X-rays

These are the most common of all dental x-rays taken as they provide a great deal of detail allowing your Toronto dentist to find cavities, evaluate the state of your tooth's roots and surrounding bone structure, monitor developing teeth and better determine the general health of your teeth and jawbone.
Some types of Intraoral X-rays are:

Bitewing X-rays

These x-rays are used to show the details of the upper and lower teeth in a specific area of the mouth. Bitewings are used  to detect any potential decay that may occur in between teeth as well as possible changes in bone density that may result from gum disease. These x-rays may also be used to check on the state of existing restorations.

Periapical X-rays

Reveal the tooth's structure in its entirety from crown to the very ends of the roots anchored in the jawbone. Periapical x-rays are used to detect possible abnormalities in the tooth's roots or surrounding bone structure.

Occlusal X-rays

Reveal the entire arch of teeth in either the upper or lower jaw. Dentists use these x-rays to monitor tooth development and placement.

Extraoral X-rays

These x-rays show teeth, but are primarily focused on the jaw and skull relationship. Your Polar Dental professional will use extraoral xrays to identify teeth that may be impacted, monitor the development and growth of the jaw in relation to the teeth, or to detect TMJ disorders.

Some types of Extraoral Xrays are:

Panoramic X-rays: Reveal the full set of teeth in both the upper and lower jaws within a single x-ray. These x-rays are useful in identifying the positioning of all fully emerged teeth as well as any potential impacted teeth. Panoramic x-rays have also been used in the successful identification and diagnosis of tumors.
Cephalometric X-ray: Commonly taken along with the panoramic x-ray, these x-rays reveal the entire side of the skull. Your Toronto dentist will use this x-ray to examine the teeth in relation to the jaw and how it is reflected in your profile. Cephalometric x-rays are often used in orthodontic cases to help your dentist develop the best possible treatment plan for you.

The Importance of Dental X-rays

Dental x-rays reveal dental problems that may have been otherwise overlooked. For example, x-rays are imperative to the early detection of oral health problems. If an oral health issue is treated early enough, more serious health problems can be prevented that would have required more extensive treatment. Dental x-rays help in the early detection of oral health problems such as the following listed below:
  • Detection of tooth decay in between teeth 
  • Diagnosing gum disease
  • Detection of developmental abnormalities in the tooth structure, positioning and bone tissue
  • Dental x-rays reveal oral health issues below the gum line so that your hygienist may identify potential problems and clean more thoroughly to prevent further complications
  • Detect unseen oral health problems that may have developed without any pain or symptoms
  • Detecting and treating infection before painful swelling occurs
  • Cysts and growths may also be detected before damage is caused to the jawbone

Dental X-ray Safety

Dental x-rays produce low radiation exposure and represent far smaller risk that letting undetected dental problems take their course. X-rays are safe for children and in fact are even more important in detecting decay before it reaches the nerve which is closer to the surface in children, as well as diagnosing gum disease, viewing results from injury, planning orthodontic treatment and detecting potential problems below the gum line. 

Pregnant women are advised not to undergo x-rays as the results to the fetus are not yet clear. If absolutely necessary, a pregnant woman should wear a doubled lead apron to minimize exposure to radiation.
