X-rays in children

When do we take children’s first X-ray?
Dental X-rays are an important part of preventive care for children. They help detect cavities, monitor tooth development, and identify potential problems early. There are two basic types of X-rays used for children. The first is a large X-ray, called an OPG, which captures all teeth in one image. The second is an interproximal X-ray, which focuses on the spaces between teeth.

Large X-rays (OPG)
We usually take a large OPG when the child’s first permanent molar erupts. This typically happens around the age of six. The OPG provides a comprehensive overview of all teeth, including those that have not yet erupted. This allows the dentist to monitor development and plan any necessary interventions.
Interproximal X-rays
Interproximal X-rays are taken when the gaps between milk teeth begin to close. This usually occurs between 25 and 30 months of age. For some children, we can take the X-ray as early as age three, while for others it may be slightly later. During the procedure, the child bites down on a small green foam pad with a sensor. To make the visit easier, we can lend this pad for practice at home. This helps children feel more comfortable and prepared for their next appointment.
Early X-rays
Sometimes an X-ray is needed earlier than usual. For example, it may be necessary after a dental injury. It is also indicated in cases of extensive decay on the chewing surfaces or when damage to a tooth root is suspected. Early imaging allows the dentist to respond quickly and prevent more serious complications.
General timeline
In general, parents can expect the first X-rays between the ages of three and four. A large OPG usually follows around the age of six. Additional X-rays may be recommended depending on the child’s individual dental development. By taking X-rays at the right times, dentists can detect issues early and provide treatment before problems worsen.
Benefits of timely X-rays
Regular and timely X-rays help protect your child’s dental health. They enable early detection of cavities, assessment of tooth eruption patterns, and identification of any underlying issues. In addition, using child-friendly methods and allowing practice at home reduces anxiety and ensures a smooth experience. Ultimately, this approach supports long-term oral health and establishes a positive attitude toward dental visits.
