Dental x-rays are taken to allow your dental providers to see inside and below your teeth; more than what can be seen by just looking in your mouth.
Digital imaging has become very common in the practice of dentistry. It is commonly thought that dental x-rays will expose you to high doses of radiation. That’s just not true!
Annual maximum dosage of radiation for a U.S. radiation worker is 50 mSv. The dosage of digital bitewings, which is 4 total x-rays, is 0.02 mSv. There are several other forms of radiation in life to consider that give off more radiation than digital dental x-rays.
