There is no standard timetable for when your child's mouth should be X-rayed. The need varies with the child's development and dental health.
If your child has had many cavities and fillings or has a high risk of tooth decay, the American Academy of Pediatric Dentistry recommends X-rays every six months.
This can help to detect cavities developing between teeth. Whether X-rays are needed also depends on how well your child brushes and flosses, and your child's diet.
Other children may not need X-rays taken as often. If X-rays aren't taken when they are needed, problems can become worse.
