Dental X-rays
Dental X-rays, also known as radiographs, are images of your teeth that your dentist uses to evaluate your oral health. They are used with low levels of radiation to capture images of the interior of your teeth and gums. These X-rays can help your dentist to identify problems like cavities, tooth decay, and impacted teeth.
Here are some key points about dental X-rays:
Purpose of Dental X-Rays
Dental X-rays are typically performed yearly or more often if your dentist is tracking the progress of a dental problem or treatment. Factors affecting how often you get dental X-rays may include your age, current oral health, any symptoms of oral disease, a history of gum disease (gingivitis) or tooth decay.
Procedure for Dental X-Rays
The procedure requires no special preparation. You’ll sit in a chair with a lead vest across your chest and lap. The X-ray machine is positioned alongside your head to record images of your mouth.
Types of Dental X-Rays
There are several types of dental X-rays, which record slightly different views of your mouth. The most common are intraoral X-rays, like bitewing and periapical X-rays.
Risks of Dental X-Rays
While dental X-rays do involve radiation, the exposed levels are so low that they’re considered generally safe for children and adults. If your dentist uses digital X-rays instead of developing them on film, your risks from radiation exposure are even lower.
Alternatives to Dental X-Rays
In some cases, other diagnostic tools may be used instead of or in addition to dental X-rays, such as visual examination or other imaging techniques
