All You Need to Know About Dental X-rays

Your dentist will use dental X-rays, also known as radiographs, to take pictures of your teeth to assess your oral health. Images of the inside of your teeth and gums are captured using these low-radiation X-rays – This might make it easier for your dentist to spot cavities and tooth decay issues. Although dental X-rays may appear complicated, they are reasonably frequent and just as crucial as regular dental cleanings.

How and why dental X-rays are used

An annual dental X-ray is usual. If your dentist keeps track of how a dental condition or treatment is doing, they could occur more frequently. Your age, oral health, any signs of an oral illness, a history of gum disease, or tooth decay may affect how often you have dental X-rays. You’ll likely have dental X-rays taken if you’re a new patient so your new dentist can fully understand your oral health.

Since their dentists may need to keep an eye on the development of their adult teeth, children may require dental X-rays more frequently than adults. The dentist can use this information to assess if baby teeth need to be removed to avoid issues like adult teeth erupting in front of baby teeth.
