Do dental x-rays cause mouth cancer?

Unlikely: While there may be a theoretical increase in risk, the radiation used in usual dental x-rays is not likely to increase the risk of oral cancer.

No: Radiation exposure is a cumulative effect on a human body. Dental radiographs use low doses of radiation to allow the dentist to see in between the teeth and diagnose otherwise undetectable decay. If proper precautions are followed, radiation exposure from dental radiographs is not a source of mutation in mouth cancers.

No: No evidence. Radiation effects are cumulative. Have dental xrays that are necessary. Avoid those that are not necessary.

Dose too Low: The X-ray exposure from a dental film is about what you get from the sun in an hour at the beach. Mouth cancer is usually caused by excessive smoking, drinking chewing tobacco or other long term abuse of your mouth. Rarely from other causes but never from dental X-rays.
