However, the fear of exposure to X-rays radiations is very common among people and most of them are often found to be concerned about its ill-effects. This fear originates primarily from the perception radiations generated by nuclear weapons.

Some considerable facts about X-rays can be found under:

1.         The X-ray devices and techniques that are used by a partcular dentist generate radiation that are well within the standards of ALARA proposed by ADA. This principle recommends that radiations must be as less as it can be worked with. Xrays are radiations but the level of radiation that is involved in medical examinations is fairly low and within safety standards. In fact, a dentist does not require high levels of X-rays radiations to detect what it wants to. For instance, DDS Valeria Lawrence uses digital radiography which is quicker more convenient and emits even less radiation than conventional devices. Besides, its results are clearer than photographic examination systems and can even be enlarged for better view.

2.         The number of times that a person is exposed to radiations of X-rays radiation is also a determinant factor of its harm. Even X-rays done by a dentist can be potentially harmful but only if a person goes through it after an interval of every 3-4 days for one whole year.
