What Are Dental X-Rays?
Dental X-rays (radiographs) are images that show the hard tissues of your mouth—teeth, bone, and surrounding structures—that are not visible during a visual exam. They help our team detect decay between teeth, bone loss from gum disease, infections at the root tip, cysts or tumors, and developmental abnormalities. Without X-rays, many dental problems would remain hidden until they become larger and more difficult to treat.
At Alameda Dental in Aurora, CO, we use digital X-ray technology to capture these images quickly, comfortably, and with minimal radiation exposure. Our team, led by Dr. Casandra Barnes, evaluates each image alongside your clinical exam to form a complete picture of your oral health and to plan treatment that is precise and personalized.
How Digital X-Rays Work
Digital radiography uses an electronic sensor instead of traditional photographic film to capture images. When X-ray photons strike the sensor, they are converted into a digital signal that appears on our computer screen within seconds. This process requires significantly less radiation than film-based systems while producing images that can be enhanced, magnified, and stored electronically.
These advanced images are invaluable for planning implant placement, evaluating impacted teeth, assessing airway issues, and diagnosing complex pathology. Dr. Barnes will explain which images are necessary for your specific condition and why.
Types of X-Rays We May Recommend
The type and frequency of X-rays depend on your age, risk factors, current symptoms, and treatment needs. Common types include:
- Bitewing X-rays: These show the crowns of upper and lower teeth in one view, primarily used to detect cavities between teeth and monitor bone levels.
- Periapical X-rays: These focus on one or two teeth from crown to root tip, useful for diagnosing abscesses, root canal issues, or deep decay.
- Panoramic X-rays: A single image that captures all teeth, both jaws, and surrounding structures. Ideal for evaluating wisdom teeth, jaw fractures, or overall development.
- Intraoral Photography: While not an X-ray, we often use a small intraoral camera to show you magnified images of specific teeth or gums, helping you understand what we see.
Who Needs Dental X-Rays?
Virtually every patient benefits from diagnostic X-rays at some interval. A new patient typically receives a full series or panoramic X-ray to establish a baseline, while returning patients with low cavity risk may need bitewings every 12 to 24 months. Patients with a history of decay, gum disease, dry mouth, or other risk factors may need them more frequently.
Children and teens often require X-rays more often than adults because their teeth and jaws are still developing and they may be more cavity-prone. Dr. Barnes and our team follow the guidelines of the American Dental Association and the FDA, recommending X-rays only when the diagnostic benefit outweighs the minimal risk. We never take X-rays on a routine schedule without considering your individual circumstances.
What to Expect During Your X-Ray Visit
The process is quick, non-invasive, and comfortable. Here is a typical flow:
- We review your health history and any recent dental changes.
- A team member will place a small digital sensor inside your mouth, positioned to capture the needed area. You may wear a protective apron and thyroid collar.
- The sensor connects to our computer, and we take the X-ray from outside your mouth. You will not feel anything.
- The image appears instantly on the screen. We may reposition the sensor a few times to get different angles.
- For a panoramic X-ray, you will stand or sit while a machine rotates around your head; it takes about 20 seconds.
After the images are reviewed, Dr. Barnes will discuss any findings with you and, if needed, outline treatment options. There is no recovery time; you can resume your normal activities immediately.
Benefits and Considerations
The primary benefit of dental X-rays is early detection. Cavities caught between teeth, bone loss beneath the gumline, and infections at the root tip are all conditions that cannot be confirmed by visual exam alone. Treating these problems early prevents more extensive and costly treatment later. Digital X-rays also allow us to show you exactly what we see, which helps you make informed decisions about your care.
A common concern is radiation exposure. We understand this and employ several measures to minimize it: digital sensors that require less radiation, lead aprons with thyroid collars, and strict adherence to the ALARA principle (As Low As Reasonably Achievable). For most patients, the amount of radiation from a set of bitewing X-rays is comparable to a few hours of background environmental radiation. If you have specific health conditions or concerns, we are happy to discuss them before any imaging is taken.
Cost, Insurance, and Payment
The cost of dental X-rays varies depending on the type and number of images needed. Many dental insurance plans cover preventive X-rays at intervals specified by the policy—often once per year or once every two years for bitewings.
At Alameda Dental, we verify your dental benefits before treatment and provide a written estimate of any out-of-pocket costs. We accept most major insurance plans and can file claims on your behalf. For a personalized estimate, call our office at (303) 343-7072.
Safety and Comfort at Alameda Dental
We take patient safety seriously. Our X-ray equipment is regularly inspected and calibrated. We follow infection control protocols that meet or exceed CDC and ADA guidelines. All sensors and surfaces are disinfected between patients.
For patients who experience anxiety or have a strong gag reflex, we take extra time to position the sensor comfortably. Techniques such as using smaller sensor sizes, taking a panoramic instead of multiple intraoral images, or simply pausing between images can help. If you have had uncomfortable X-ray experiences in the past, let us know so we can tailor our approach.
