A dentist sees a lot, but not everything. Some changes - such as caries between teeth, inflammation at the root or bone loss -are hidden beneath the surface. That's why we often use X-rays in the examination to help make an accurate diagnosis and make treatment safer.
Is X-ray safe?
Yes. Modern devices use a very low radiation dose. One dental picture means less radiation than a short plane flight.
Types of X-ray images
- Intraoral image - single tooth or pair of teeth, most accurate
- Orthopan (OPG) - complete examination of both jaws
- CBCT (3D image) - when an accurate 3D assessment is needed (e.g. for an implant)
What can we see with an X-ray?
- initial cavities between the teeth
- inflammation of the tooth root or surrounding tissue
- the condition of the bones and the presence of any periodontal disease
- position of wisdom teeth
- the quality of old fillings or root fillings
- cracks or damage to teeth
- teeth that have not yet grown in (in children and adolescents)
When is imaging recommended?
- at first inspection, for a comprehensive assessment of the situation
- before or during treatment, e.g. root canal
- pain or suspicion of a hidden change
- as a routine check-up for periodontal patients
- before major procedures such as implants or orthodontics
When is imaging recommended?
An X-ray is not just an additional examination - it is the basis for safe and accurate treatment. It allows problems to be detected in time and treatment to be carried out without guesswork.
A visit to the dentist involves looking where your eyes can't see - and with good reason.
