Regular dental x-rays may only be required when the permanent teeth have grown. Children who have baby teeth will require dental x-rays only if the need arises, according to the American Dental Association.
Key takeaways:
- Dentists should perform dental x-rays every 6-12 months for high-risk preschoolers who have had cavities in their baby teeth.
- Dental x-rays should be considered only every 12-24 months for younger children who have never had a tooth cavity.
- Dentists can recommend cone beam CT scans to get 3-D x-ray images of the teeth and their roots as well as the jaw and the skull.
But there always needs to be a justification for using X-rays. Some reasons include impacted teeth, pain, obvious decay, unexplained bleeding, migrating teeth, or again, simply because a dentist can’t see between two teeth.
