Dental X-rays

Alternative names:

X-rays of the teeth

How the test is performed:

The test is performed in the dentist's office. The most common procedure is a "bite-wing", where a small piece of film is placed in the mouth behind a section of the teeth. You are asked to bite down on the paper tab around the film, which holds the film in place. The X-ray machine is aimed at that section of teeth, and a picture is taken. Most dental X-rays include 4 or more views of the teeth.

How to prepare for the test:

Adults:
There is no special preparation.

Infants and children:
The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experience, and level of trust. For specific information regarding how you can prepare your child, see the following topics as they correspond to your child's age:

• infant test or procedure preparation (birth to 1 year)
• toddler test or procedure preparation (1 to 3 years)
• preschooler test or procedure preparation (3 to 6 years)
• schoolage test or procedure preparation (6 to 12 years)
• adolescent test or procedure preparation (12 to 18 years)

Notify the dentist if you are pregnant.

How the test will feel:

The X-ray itself causes no discomfort. Some people find that biting on the piece of film makes them gag; slow, deep breathing through the nose usually relieves this feeling.

Why the test is performed:

Dental X-rays are useful in the diagnosis of dental diseases and injury.
