There’s a lot going on in your mouth that is not visible to the naked eye, and dental X-rays allow your dentist to see what’s happening below the surface. By taking X-rays, your dentist is provided with a comprehensive assessment of the health of your mouth.
Tooth decay can be sneaky ‘ it doesn’t tend to show physical signs of its presence early on. X-rays are an important diagnostic tool that allows your dentist to confirm if you have tooth decay, or if you have any problems such as infection around the roots of the tooth, or bone loss. Spotting it early means your dentist can deal with the problem before it becomes a significant issue.
Regardless of whether you’re a child or an adult, you can have X-rays safely taken of the inside and outside of your mouth. The amount of radiation involved is extremely low, and is equivalent to the sort of exposure you’d receive on a 1-2 hour flight. This means that even if you’re pregnant you can have X-rays taken, although they are generally kept to a minimum during this period.
Oh, and that thing about your dentist leaving the room while the X-rays are taken? Nothing to worry about there ‘ they’re taking lots of X-rays all day long and stepping out of the room limits their ongoing exposure to radiation.
The types of X-rays your dentist will take will depend on the conditions they are assessing you for. The decision to take an X-ray, and the type of X-ray taken, will be influenced by such things as your past and present oral health, an examination of your mouth, your age, risk of disease and any early symptoms of oral disease.
If an X-ray uncovers decay, your dentist will likely opt for fillings as the preferred treatment.
