- For Children: As a child's teeth are emerging, they need more dental X-rays compared to adults. Also, their teeth are smaller and their jaws are still developing. Essentially, dental X-rays monitor tooth decay or cavities early on.
- For Adolescents: If there is a medical history of severe dental problems or teeth restorations, adults undergo dental X-rays. This is done every six to 12 months just to make sure that teeth decay is treated well.
