While your child may be fine without an x-ray, utilizing radiographs is the only way to ensure that there are no potential issues lying below the gum line. The fact is x-rays are a tried and true medical technology in use for over a century and without the use of x-rays, some important dental or orthodontic issues can be missed by a visual inspection. X-rays allow an in-depth look at where cavities might start to develop below the gums and even help dentists catch cavities that have been missed. Dental x-rays are also useful for evaluating how teeth are developing, whether adult teeth are coming in at the correct angles, checking for trauma or injury, and overall help keep track of your child’s oral health development. Also, modern x-rays are much safer than their older counterparts were.  The radiation dose is a fraction of what it used to be. You can always ask for a lead apron to be used while the x-rays are being taken to lower the radiation dose even further.
