Are dental X-rays safe?
Yes. New digital X-ray machines limit the low-dose radiation to a beam that targets only the areas needing to be filmed, faster film speeds allow for shorter exposure times, and the use of film holders prevents slipping, reducing the need for repeated exposure due to retakes. Stray radiation is almost non-existent with the use of modern dental X-ray machines, but the use of lead-lined, full-body aprons protect against even that possibility. Every two years, federal law requires X-ray machines to be checked for safety and accuracy, and some states have even more stringent regulations.
