Dental X-rays are used to diagnose the health of your teeth. They complement the visual analysis of the surface of the tooth. They allow the dentist to access important places which cannot be seen during the visual examination, such as the maxillofacial skeleton, joints, teeth and gums – so they are used as an important diagnostic tool. Thanks to them, your dentist can intervene quickly before a small problem becomes a much larger one.
The frequency with which your dentist will ask you to take X-rays depends on the health of your teeth and how often you visit. Your dental health history is also a guide; if you have few or no cavities, then your dentist may not need to take X-rays every six months.
Also, remember that the amount of radiation is minimal. A dental X-ray is about 20 times less exposure than a typical medical radiography. In addition, you wear a protective lead apron to limit exposure to only the target areas.
There are four types of X-rays:
- Periapical X-rays: isolates a group of teeth at their apex for a better analysis;
- Interproximal X-rays: shows the interproximal surfaces between the teeth including the bone part;
- Panoramic X-rays: allows an overview of both maxillaries including nasal cavities and articulation;
- The cephalogram X-ray: includes the skull and jaw to see teeth evolution.
At any time, you may ask your dentist at Sky Harbour Dental why he/she deems it necessary to take dental x-rays and they will explain the reasons. After all it is your health, and you deserve to get as much information as possible.
