Digital X-rays use a small electronic sensor instead of film to capture detailed images of your teeth, roots, and jawbone, with far less radiation than traditional X-rays. At Dentistry at Millennium Park, they help us spot problems like hidden cavities and bone loss early, and the images appear on screen instantly, right here in Chicago's Loop.
Digital X-rays, also called digital radiography, are a modern alternative to traditional film X-rays. Instead of film, we use a small electronic sensor that captures images of your teeth, roots, gums, and jawbone and sends them straight to a screen in seconds.
They show us what a visual exam can't: the areas between teeth, beneath existing fillings, below the gumline, and inside the bone. That clearer picture helps us catch problems early, when they're easier and gentler to treat.
Best of all, digital X-rays use significantly less radiation than the film X-rays many of us remember, and there are no chemicals or waiting for film to develop. It's a faster, safer, more comfortable experience.
Digital X-rays are an important part of thorough, preventive care. We use them to:
Note: We take X-rays based on your individual needs, often at your first visit and periodically after that, not necessarily at every appointment.
A digital X-ray can help us spot:
Cavities between teeth or under existing fillings
Decay that isn't visible to the eye
Bone loss linked to gum disease
Infections or abscesses at the root of a tooth
Impacted or extra teeth
Cysts or other abnormalities in the bone

Dental X-rays are part of diagnostic care, and dental insurance commonly covers necessary X-rays, often alongside your exam. We're in-network with most major PPOs and will review your specific benefits with you.
Our in-house membership plan includes your X-rays as part of your covered care, and we offer financing through CareCredit and Cherry for any treatment beyond routine visits.
Yes. Digital X-rays use very low levels of radiation, significantly less than traditional film X-rays and a small amount compared with many everyday sources of exposure. They're considered very safe for routine dental care.
We take your safety seriously. We follow the principle of using as little radiation as reasonably possible, protect you with a lead apron and thyroid collar, and only take X-rays when they're genuinely useful for your care rather than on fixed schedule. If you are or might be pregnant, let us know so we can take extra precautions.
Modern technology lets us provide more accurate, more comfortable, and more conservative care. Our low-radiation digital X-rays mean clearer answers with minimal exposure, and we always take the time to show you what we see and explain why it matters.
As a proudly woman-owned, all-female practice in the heart of the Loop, led by a woman of color, we pair modern dentistry with genuine, personal care.
