Why Do We Take Them?

Dental x-rays are useful diagnostic tools which provide valuable information to the dentist about your teeth and the structures around them. This helps the dentist to make the right diagnosis and give you the right treatment.

What Is An X-Ray?

An x-ray is a form of electromagnetic radiation which is produced when charged particles lose energy. These particles are generated by an x-ray machine and are directed through the tissues in a controlled way, they are recorded onto a film which is developed or onto a sensor which produces an instant digital image. There are three main types of x-ray that are commonly taken in our practice, these are; The Bitewing Radiograph, The Periapical Radiograph, The Panoramic Radiograph (or OPG). We also provide Cone Beam CT scans for more advanced 3D diagnoses.

Left Bitewing

In our practice we have invested in the latest digital x-ray technology which has significant benefits over conventional film radiographs these benefits include:

  • Reduced radiation dose of up to 90%, compared to conventional film radiographs
  • No chemicals required for processing, which is kinder to the environment
  • The image is produced virtually instantly on a computer screen
  • The image can be manipulated to improve viewing and diagnosis
  • The original image can be saved onto the computer along with your records


What Are The Risks Of Having An X Ray?

Virtually everything we do in our daily lives carries some risk; form walking down the stairs to driving the car into work. Although no radiation source is ever 100% safe and even conventional film based x-rays use only small amounts of radiation the digital equipment used in our practice for taking dental x-rays uses the latest technology to reduce the amount of radiation even further.

There is background radiation all around us which comes from both natural and man-made sources, these include:

  • Cosmic rays from outer space
  • Radon gas
  • Radioactive minerals which remain from the very early formation of the planet
  • Radioactive fallout from man-made sources such as previous nuclear explosions/weapons
  • Food
  • Air Travel

Right Bitewing

To help you understand the levels of radiation involved and the risk, the examples given below compare how much background radiation is equivalent to the following x-rays:

  • 2 Standard Bitewing x-rays – 8 hours or a return flight from Spain
  • 1 Panoramic x-ray – 28 hours
  • 1 Chest x-ray – 160.8 hours

Can I Still Have An X-Ray If I Am Pregnant?

Although the radiation form a dental x-ray is relatively small the developing baby in the womb may be more sensitive to radiation and therefore may be at higher risk. If you know or think you may be pregnant then please inform the dentist on your visit. If an x-ray is required the x-ray can be postponed until after the baby is born or if it is urgently required to make a diagnosis special precautions can be taken to minimise the risk.

Any Other Questions?

If you have any other questions or concerns over dental x-rays the dentists at the practice would be happy to answer these on your next visit to the practice.
