Yes, when used appropriately
Dental X-rays are considered safe for children, with modern X-rays having very low levels of radiation. That said, we still aim to minimise the amount to the lowest amount reasonably achievable.
Why X-rays may be needed
Dental X-rays use very low levels of radiation and are only taken when they are needed to help diagnose or monitor something that cannot be seen properly during a visual examination. For example, X-rays can help detect decay between teeth, assess infection, check tooth development, review trauma, or monitor adult teeth that are developing underneath the gums. Their particular benefit is seeing everything that our eyes can't, and so many things in dentistry occur invisibly, X-rays are paramount to being able to diagnose and treat disease.
We only take X-rays when needed
We only recommend X-rays when the benefit of the information outweighs the very small radiation exposure. The type and timing of X-rays depends on your child’s age, symptoms, dental history and risk of decay.
