Ask a Dentist in Hollywood: Should I Have Dental X-rays Taken? And Are They Safe?

Dental radiographs, or dental X-rays, are integral to a comprehensive and ongoing oral health plan. Along with brushing and flossing and regular professional teeth cleanings, X-rays are essential. While a lot can be learned by an oral examination, X-rays give your dentist a deeper and more complete look at the health of your mouth, highlighting areas that would be impossible to see otherwise (i.e., between and inside of your teeth).

So why do some opt out of X-rays or feel hesitant about consenting? Why does the word radiation elicit a fear response? Well, probably because radiation is often associated with cancer and bombs. But whether we like it or not, radiation is all around us all the time, and we are exposed to far higher amounts in our daily lives than in the dentist’s chair.

Take this stat, for example: The amount of radiation emitted to obtain bitewing radiographs (two to four images of the back teeth) is about 0.005 millisieverts (mSv), whereas the average American is exposed to 3.2 mSV every year just from our daily environment. Moreover, when you get dental X-rays, your body (and organs) are protected by a lead apron mitigating exposure.

The benefits of dental X-rays exceed the very low levels of radiation emitted.

What are the benefits of X-rays?

Dental radiographs can help your dentist see the following:

Cavities between your teeth
Infections underneath your gums
Certain types of tumors
Signs of periodontal disease
Changes in your hard tissue (teeth and bone) and soft tissue around your teeth and jaw bones
Early signs of problems that can become serious health issues (The earlier an issue is detected, the easier and more cost-effective it is to treat.)

How often should I have dental X-rays taken?

For most, dental X-rays aren’t taken that often. If you don’t have any underlying oral health problems, your dentist might only snap photos of your mouth every couple of years. Everyone’s oral health case is different, though. Your dentist will determine the best frequency based on an oral examination, health history, risk of oral disease, age, and any reported symptoms, among other factors.

So, to answer the question, “Should I have dental x-rays taken, and are they safe?” — yes and yes!
