Did you know that a single dental x-ray has the same radiation as eating 2 banana’s? 
Even our OPG x-rays are equal to a short flight on a plane. 
X-rays are an important step in the diagnosis of not only tooth decay that can not be seen by the naked eye but to see infection around the roots of the tooth and bone loss.
Finding this early means that your dentist can potentially treat the problem at an early stage rather than become more extensive.
