1. X-rays help dentists reduce pain and suffering by detecting cavities early, before they get to the stage of painful toothaches and are an economical way of keeping your dental costs low.
2. Dental x-rays deliver a small amount of radiation to our tissues compared to annual dose of radiation we are exposed to from all other natural sources.
3. The more complex and comprehensive treatments that dentists provide would be simply impossible without first taking x-rays of a patient’s teeth or jaws.
