Why does a dentist need a dental X-ray to examine my teeth?
Dental X-rays are often used to detect dental disease and other pathology that may not be visible from a dental exam. This could include decay or tooth abscesses that occur beneath fillings, or in the root canal as a result of an infection.
Dental X-rays are also used to help dentists identify bone changes that occur due to infections. This allows the dentist to prepare for wisdom tooth extractions, root canal treatment, dental implants, dentures, and other dental procedures.
Are dental X-rays safe?
Dental X-rays are safe as the radiation levels from the X-ray are low. A lead apron will be placed over your body to prevent unnecessary radiation exposure to your vital organs. You should inform your dentist if you are pregnant or suspect that you may be pregnant, because radiation is not safe for developing fetuses. Pregnant women should avoid getting an X-ray.
What types of dental x-rays are there?
Common intraoral X-rays include:
This is a routine screening X-ray used to check for decay between your teeth. Your dentist will usually take one Bitewing X-ray of each side of your mouth as part of a routine examination.
This is often used by paediatric dentists and orthodontists to track the development of a child’s teeth. The process is similar to the Bitewing X-ray.
This is used to allow the dentist to check your wisdom teeth, plan for dental implants, or assess jaw problems. The machine rotates around your head to take an image of your entire mouth. It provides a useful amount of information on your mouth’s general health. However it is not as high definition as a Bitewing or Periapical X-ray, so these may need to be taken to compliment the Panoramic X-ray.
This shows a detailed view of your tooth, especially focusing on the roots and area around the end of the roots. The X-ray will allow the dentist to check for unusual changes in the root of your tooth and its surrounding bone structures.
How often should I get a dental X-ray?
This will depend on the condition of your teeth and your risk of developing dental disease. Regular dental X-rays are recommended for screening purposes and the time between X-rays can vary from six months to three years depending on the need.
