The next time you take your child to the dentist, you might notice the dental hygienist does not use a lead shield during their X-ray. This is because the American Dental Association now recommends that dentists remove lead shielding during X-rays.
Parents are sometimes concerned about radiation exposure during X-rays, which is understandable, says Emily Hahn, DDS, a pediatric dentist at St. Louis Children’s Hospital. However, the level of radiation exposure during dental imaging has decreased as technology has improved. So why not leave the lead shielding on just in case? Studies show that sometimes it interferes with the X-ray, leading to repeated imaging — and additional radiation exposure.
You can also reduce the likelihood your dentist will need to take X-rays at every visit by preventing cavities. For your child, this means ensuring they:
- Brush twice a day
- Use fluoride toothpaste
- Floss regularly
- Go to checkups every six months
