Dental x-rays are now done with digital radiography. This technology uses electronic sensors that capture and store digital images. These images can be instantly viewed by the dentist to detect dental issues. This new technology reduces exposure to radiation by 80 to 90 percent.
Dental x-rays are used to identify a variety of issues such as bone loss, tooth decay, cysts, decay between teeth, development issues, poor tooth or root positioning, issues in the tooth or below the gum line, cancerous and non-cancerous tumours.
The frequency of x-rays depends on individual circumstances.
