Dental x-rays are pictures of the internal structure of your teeth and bones. X-rays are a form of energy that moves in waves. When theses waves travel through solid objects such as your teeth, the waves are either absorbed or pass through the object. As our teeth and the surrounding hard tissues are dense, so they absorb x-rays. Conversely because the gums are less dense, so x-rays continue to pass through them. This phenomenon results in such pictures that allows your dentist interpret the changes into several different diagnosis, which could help preventing any future dental problems such as tooth decay , cysts, abscesses, bone loss through gum disease, trauma, fractures, Bone infections or abnormalities, and detection of impacted teeth. There are currently three different types of dental x-rays commonly used for an oral examination, the frequency and the indication of these dental radiographs depends on the individual circumstances.
