Yes, dental x-rays are a safe and vital tool we use for measuring and monitoring your oral health. We feel it is imperative to ensure that our patients have the facts — especially when it comes to their oral healthcare. This is why we want to respond to this important question about the safety of dental x-rays.
We want you to know what they are, how they are used, what makes them a safe and effective tool, and why they are so important to dentistry and your health. X-rays are a form of electromagnetic radiation, in fact, just like natural daylight, except they have a much shorter wavelength. And because they are a form of ionizing radiation, they can easily penetrate bodily tissues without causing any harm when used properly. The reasons we use them are obvious; they help us literally see what is unseen. For example, they enable us to see bone structure and roots of teeth among other things, and are commonly used for diagnosing tooth decay. Furthermore, today's x-ray machines and other image capturing techniques are so sophisticated and sensitive that the amount of radiation required for diagnosis is almost nothing when compared to what you get from the background radiation present in everyday living. In fact, the average single digital periapical (“peri” – around; “apical” – root end of a tooth) film is equal to 1/10 the amount of everyday natural environmental exposure. These facts make it clear that dental x-rays are completely safe and, thus, are nothing you need to be concerned about.
