As a parent, you want what’s best for your child’s health. So when their pediatric dentist recommends X-rays, it’s natural to have questions. How safe are they? Are they really necessary? What will they show?
Understanding the role of dental X-rays in your child’s oral health can help you feel confident about this common diagnostic tool.
What Are Pediatric Dental X-rays?
X-rays use a very small amount of radiation to take images of not just teeth, but bones and tissue beneath the surface of your teeth and gums. For children, X-rays serve several important purposes.
X-ray images reveal important information that isn’t visible during a regular dental exam. They help dentists detect cavities between teeth, monitor the development of permanent teeth, identify problems with tooth alignment, and check for infections or other issues that may need treatment.
How Safe Are Dental X-rays for Children?
The good news is that dental X-rays are very safe. The amount of radiation exposure from a dental X-ray is extremely low. It is about equal to the radiation you would be exposed to during a short airplane flight.
Still, measures are taken to minimize exposure. A lead apron will cover your child’s body during the X-ray, which can also feel like a comforting blanket. In addition, the X-ray beam is a focused on a very specific area to expose the patient as little as possible.
Moreover, modern digital X-rays reduce radiation exposure by up to 80% compared to older film X-rays, making them safer than ever before. Lastly, remember that we will only recommend X-rays when the diagnostic benefits outweigh any minimal risk.
When Does My Child Need Their First Dental X-rays?
The timing of your child’s first X-ray depends on their specific needs. Some children may need X-rays as early as age 2 or 3, while others may not need them until they’re a bit older.
We will consider several factors when deciding if X-rays are needed. These include your child’s age, risk of tooth decay, signs of dental disease, and whether they’re experiencing any symptoms like pain or swelling.
How Often Will My Child Need Dental X-rays?
When determining X-ray frequency, we take into account recommendations from the American Academy of Pediatric Dentistry so that X-rays are taken only when necessary for proper diagnosis and treatment planning. That being said, there’s no one-size-fits-all answer. The frequency of X-rays depends on your child’s oral health and their risk factors for dental problems.
For children with healthy teeth and a low risk of decay, X-rays may only be needed once every year or two. Children with a higher risk of cavities or ongoing dental issues may need X-rays more often.
Children at higher risk for cavities may need X-rays more frequently. This includes kids who consume sugary foods or drinks regularly, those who don’t brush and floss consistently, or children with a history of cavities.
What Types of Dental X-rays Might My Child Receive?
Several different types of X-rays serve different purposes in pediatric dentistry. Bitewing X-rays show the upper and lower back teeth in a single view. These are commonly used to check for cavities between teeth.
Periapical X-rays capture the entire tooth from crown to root. They help dentists see the root structure, surrounding bone, and any developing permanent teeth underneath.
Panoramic X-rays provide a broad view of the entire mouth, including all the teeth, jaws, and surrounding structures. These are particularly useful for monitoring how permanent teeth are developing and identifying potential orthodontic issues.
We will choose the type of X-ray based on what information they need to assess your child’s oral health. For a full picture, we will typically take a few different types of images during your child’s visit.
Can I Stay with My Child During Their X-rays?
We encourage parents to stay with their children during most dental procedures. However, while dental X-rays are generally safe, repeated exposure to radiation over time can add up. Since you are not the patient receiving the diagnostic benefit, it makes sense to minimize your exposure. So we may ask you to step out of the room, stand behind a protective barrier, or wear a lead vest.
What Happens if My Child Won’t Cooperate?
Some children feel nervous about dental procedures, including X-rays. The good news is that pediatric dental teams are experienced with helping anxious children. We will talk with you and your child beforehand and explain what will happen in simple, child-friendly terms.
If your child still struggles to stay still for the X-ray, we may suggest trying again at a future visit when your child is older and more comfortable. In some cases, sedation options may be discussed for children who need X-rays but have severe anxiety.
