Why does your Dentist take X-rays

Dental X-rays allow your dentist to see what’s going on beneath the surface of your teeth and gums that you can’t see with your own eyes. X-rays allow your dentist to examine the health of your mouth in great detail.

Tooth decay is notorious for being evasive, as it does not often present visibly until much later. X-rays are essential for identifying dental problems since they can indicate to your dentist whether or not you have tooth decay or other problems such as an infection at the tooth’s root or bone loss. Early detection allows your dentist to fix the problem before it worsens.

Whether you’re a toddler or an adult, you can have X-rays of the inside and outside of your mouth taken safely. In terms of low-level exposure, the radiation dose is comparable to that of a 1-2 hour flight. This means that even if you’re pregnant, you can still have X-rays, though they will still be limited.

You know how your dentist walks out of the room while the X-rays are being taken? They take a lot of X-rays all day, so simply leaving the room minimises their radiation exposure.

Why are X-rays required?

The conditions being investigated by your dentist will dictate which X-rays are used. If you opt to have an X-ray, the type of X-ray you obtain will be determined by your oral health history, inspection of your mouth, age, disease risk, and any early oral disease indicators.

What can dental X-rays reveal about your dental health?

  • Unnoticeable degradation in the spaces between the teeth, as well as existing fillings, canals, crowns, or bridges that should be fixed
  • The presence or absence of gum disease, as well as the severity of the condition
  • Other infections, such as an abscesse
  • Tooth development issues, such as crooked or extra teeth, etc.
  • Cysts and certain forms of tumours
  • Dental and bone fractures, caused by traumatic injuries
  • Teeth proximity to nerves and sinuses
  • The emergence of wisdom teeth and if they should be extracted

If an X-ray indicates decay, the dentist will discuss treatment options with you. These may include preventive treatments to slow or stop the spread of decay, as well as a filling if there is a cavity.
