Dental X-rays are used for detecting cavities that cannot be seen during visual inspections, such as decay between teeth and also for checking for bone loss or a dental infection that affects the root of the tooth.
If your overall dental health is good and you visit your dentist every few months, it is enough to have an X-ray every two or three years. However, the dental patients who belong to the following categories may need more frequent X-rays:
- Teenagers whose dentures are developing may need an X-ray every 6 months, especially if their dentures are corrected with braces.
- Patients who have very many fillings or other restorations such as implants, crowns or bridges
