Dental x-rays are an extremely important part of your dental exam. Dental x-rays offer a better picture of your dental health and can detect any hidden problems or abnormalities. When the x-rays go through the mouth, the denser parts like your teeth will show up giving the dentist a clear picture of any cavities or tooth decay.
Depending on the patients dental health will determine how often they need dental x-rays. It’ ultimately up to the dentist to determine how often you need x-rays. His determination is based on his original examination of your dental health and medical health.
The frequency is also determined by the patients age, risk for disease and signs and symptoms. Children often need dental x-rays more frequently because their teeth and bones are still developing. They are also at more risk of tooth decay than adults.
