Dental X-rays (radiographs) are images of your teeth that your dentist uses to evaluate your oral health. These X-rays are used with low levels of radiation to capture images of the interior of your teeth and gums. This can help your dentist to identify problems, like cavities, tooth decay, and impacted teeth.
Dental X-rays may seem complex, but they’re actually very common tools that are just as important as your teeth cleanings.
Dental X-rays are typically performed yearly. They can happen 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
- your current oral health
- any symptoms of oral disease
- a history of gum disease (gingivitis) or tooth decay
If you’re a new patient, you’ll probably undergo dental X-rays so that your new dentist can get a clear picture of your dental health. This is especially important if you don’t have any X-rays from your previous dentist.
Children may need to have dental X-rays more often than adults because their dentists might need to monitor the growth of their adult teeth. This is important because it can help the dentist determine if baby teeth need to be pulled to prevent complications, such as adult teeth growing in behind baby teeth.
