A tooth can look perfectly healthy from the outside while decay develops between teeth, beneath an old filling or near the root. Digital X-rays in Las Vegas, NV, give our team a view of areas that cannot be examined with the eyes alone.
At Preferred Family Dentistry, Dr. Salmeh Jafarifar uses digital images when they are needed to answer a specific diagnostic question, monitor a known concern or plan treatment. The images appear on a computer screen within moments, allowing her to examine small details and show you what she sees.
Call 702-433-0355 to schedule a dental examination and learn whether updated X-rays are appropriate for your smile.
What Can Digital X-Rays Show?
A visual examination reveals the exposed surfaces of your teeth and gums. X-rays provide additional information about the areas beneath restorations, between neighboring teeth and below the gumline.
Depending on the type of image taken, digital X-rays may help Dr. Jafarifar identify or evaluate:
- Decay between teeth
- Cavities developing beneath existing fillings or crowns
- Infections near the roots of teeth
- Changes in the bone supporting the teeth
- Cracked, damaged or unusually shaped roots
- Teeth that have not erupted normally
- Areas affected by gum disease
- Previous root canal treatment
- The condition of teeth supporting a dental bridge
- Changes that should be monitored over time
Digital X-rays are an important diagnostic resource, but they do not replace a clinical examination. Dr. Jafarifar combines the images with your symptoms, dental history, visual findings and other tests before making a diagnosis.
Seeing Beyond the Visible Tooth
Many dental problems begin in places that are difficult or impossible to see directly. Decay often develops where neighboring teeth touch, while an infection may form around the tip of a root beneath the bone.
Digital imaging can be particularly useful when:
- A tooth hurts but appears normal during a visual examination
- Floss repeatedly catches or tears in one area
- A large filling or crown needs to be evaluated
- Gum measurements suggest a loss of bone support
- A tooth has changed color after an injury
- You experience pain when biting
- A damaged tooth may need restorative treatment
- Dr. Jafarifar needs to compare current findings with earlier records
Finding a concern before it causes obvious pain may allow for a more conservative treatment plan. For example, a smaller cavity may be repaired with a composite dental filling, while extensive decay may eventually require a crown or root canal treatment.
How Digital Dental X-Rays Work
Digital radiography uses an electronic sensor rather than conventional film. The sensor records the image and sends it to the dental computer, where it can be viewed shortly after exposure.
The digital format allows Dr. Jafarifar to:
- Enlarge areas that require closer inspection
- Adjust brightness or contrast to review specific details
- Compare current images with earlier records
- Display findings during your appointment
- Store images as part of your dental record
- Share appropriate records with another dental provider when needed
Because the images do not require film development, there is no need for the chemical processing associated with conventional dental film.
Your X-Rays Are Chosen for a Reason
Digital X-rays are not automatically taken at every appointment. The images recommended for one patient may be different from those appropriate for another.
Before recommending new images, Dr. Jafarifar may consider:
- Your age and stage of dental development
- Your history of cavities or gum disease
- Current pain, swelling or sensitivity
- The number and condition of existing restorations
- Findings from your clinical examination
- Whether you are a new or established patient
- The date and quality of your previous X-rays
- Treatment being considered
- Changes in your medical or dental health
This individualized approach avoids using the same imaging schedule for every patient while still obtaining the information needed for responsible diagnosis and treatment planning.
When Digital X-Rays May Be Recommended
There is no single reason for taking a dental X-ray. The type and timing depend on what Dr. Jafarifar needs to examine.
During a New-Patient Examination
Recent diagnostic records can help establish a clear picture of your current oral health. If you have usable X-rays from another practice, ask whether they can be transferred before your appointment. Dr. Jafarifar will determine whether those images provide the information needed or whether additional views are appropriate.
When You Have Tooth Pain
When a tooth hurts, an image may help reveal deep decay, an infection, changes around the root or another source that is not visible from the outside.
Patients with severe or sudden symptoms can learn more about urgent care on our Emergency Dentistry page.
To Monitor Cavity Risk
Patients who frequently develop cavities may need imaging at different intervals than patients with a consistently low risk. Images can help identify decay between teeth before it becomes large enough to see directly.
To Evaluate Gum Health
Gum disease can affect the bone that supports the teeth. Digital images may help Dr. Jafarifar assess bone levels alongside gum measurements and other periodontal findings.
Before Restorative Treatment
X-rays may be useful when planning a porcelain dental crown, dental bridge, root canal or another restorative procedure. The image helps evaluate the root, surrounding bone and areas beneath existing dental work.
What Happens When Digital X-Rays Are Taken?
For many routine images, a small digital sensor is positioned inside your mouth near the teeth being examined. You will be asked to remain still while the X-ray unit is aligned and the image is captured.
The process generally involves:
- Positioning the sensor near the appropriate teeth
- Adjusting the X-ray unit to capture the intended area
- Asking you to hold still briefly
- Taking the image
- Reviewing its clarity and diagnostic value
- Displaying the image for examination
Several images may be needed to view different parts of the mouth. The exact number depends on your symptoms, dental history and the reason for the examination.
Are Dental X-Rays Uncomfortable?
Taking an X-ray should not hurt, although the sensor may feel firm or awkward inside the mouth. Some patients find certain positions more difficult because of a small mouth, sensitive tissues or a strong gag reflex.
Tell our team if you:
- Have a sensitive gag reflex
- Experience discomfort when biting
- Have a sore tooth or injured area
- Have difficulty keeping your mouth open
- Need a short break between images
Our team can adjust positioning when possible and guide you through the brief process. Clear communication is especially helpful when one part of your mouth is already painful.
Understanding Radiation and Dental Imaging
Dental X-rays use ionizing radiation, so they should be taken only when their expected diagnostic value justifies the exposure. Digital sensors and carefully selected settings allow the practice to obtain useful images efficiently.
Radiation safety involves more than the equipment itself. It also includes:
- Taking images only when clinically appropriate
- Selecting the views needed for the diagnostic question
- Using exposure settings suited to the patient and image
- Positioning the sensor and equipment carefully
- Avoiding unnecessary repeat images
- Reviewing available previous records when appropriate
Dr. Jafarifar weighs the benefits of the diagnostic information against the small radiation exposure involved. You are welcome to ask why an image is being recommended and how it may affect your treatment plan.
Digital X-Rays During Pregnancy
Tell our team if you are pregnant, may be pregnant or are trying to become pregnant. This information allows Dr. Jafarifar to consider the urgency of the dental concern and whether imaging is needed at that time.
Dental pain and infection should not be ignored during pregnancy. When an X-ray is necessary to diagnose an urgent problem or guide treatment, Dr. Jafarifar will discuss the reason for the image and the steps used to limit exposure.
Routine or nonurgent imaging may be approached differently depending on your oral health and the clinical circumstances. Recommendations are made individually rather than according to one policy for every patient.
Digital X-Rays for Children
Children do not automatically receive X-rays simply because they have reached a certain age. Images may be recommended based on tooth development, cavity risk, symptoms and what can be seen during the examination.
Digital X-rays may help evaluate:
- Decay between closely spaced teeth
- The development of permanent teeth
- Teeth that have not erupted as expected
- Dental injuries
- Areas that are difficult to inspect directly
- Changes in a child with a history of cavities
Preventive care such as fluoride treatment and dental sealants may also be recommended according to the child’s individual cavity risk.
What Digital X-Rays Cannot Tell Us
Although X-rays reveal important information, no single diagnostic tool shows every dental problem. Some cracks, early enamel changes, bite-related conditions and soft-tissue concerns may not appear clearly on an image.
A complete evaluation may also involve:
- Looking closely at the teeth and gums
- Checking existing fillings and crowns
- Measuring gum pockets
- Testing temperature response
- Applying gentle biting pressure
- Checking tooth movement
- Reviewing your symptoms and health history
- Using an intraoral camera to inspect visible areas
This is why digital imaging works best as part of a thorough dental exam, not as a substitute for one.
Looking at the Images Together
One benefit of digital imaging is the ability to view an enlarged image on a screen. Instead of simply being told that a problem exists, you may be able to see the area Dr. Jafarifar is evaluating.
She can point out:
- Where decay appears to be developing
- How close a cavity is to the center of the tooth
- Changes around a tooth root
- Bone levels surrounding the teeth
- The condition of an older restoration
- Areas that should be monitored at future visits
Seeing the image does not mean you are expected to interpret it yourself. Dr. Jafarifar will explain the relevant findings, what they may mean and whether treatment or continued monitoring is recommended.
From Diagnosis to a Practical Treatment Plan
An X-ray does not determine treatment by itself. Two teeth with similar-looking images may require different care depending on symptoms, remaining structure, bite pressure and clinical findings.
After reviewing all available information, Dr. Jafarifar may recommend:
- Monitoring an area for changes
- Improving preventive care
- Repairing decay with a composite filling
- Replacing a damaged restoration
- Protecting a weakened tooth with a crown
- Providing root canal treatment for an infected tooth
- Treating gum disease
- Referring you to another provider when appropriate
You will have an opportunity to ask questions and understand why a particular approach is being recommended.
Experience Matters After the Image Appears
Technology can capture a detailed image, but clinical experience is necessary to place that image in context. Dr. Jafarifar has practiced dentistry since 2004 and has led Preferred Family Dentistry since 2006.
Her experience includes thousands of fillings, crowns, bridges, bonding treatments and periodontal cases. This restorative background helps her evaluate whether a finding requires immediate treatment, preventive attention, continued observation or referral.
Dr. Jafarifar has also completed approximately 500 hours of continuing education beyond dental school. Digital X-rays, intraoral cameras and other diagnostic tools support her patient-centered approach by helping her gather information and explain treatment clearly.
FAQ About Digital Dental X-Rays
What are digital dental X-rays?
Digital dental X-rays use an electronic sensor to capture images of teeth, roots and surrounding bone. The images appear on a computer screen and become part of your dental record.
Are digital X-rays safe?
Dental X-rays involve a small amount of ionizing radiation. Dr. Jafarifar recommends them only when the expected diagnostic information is appropriate for your individual needs.
How often should dental X-rays be taken?
There is no universal schedule for every patient. Frequency depends on your age, cavity risk, gum health, symptoms, previous records and current clinical findings.
Why do I need X-rays if none of my teeth hurt?
Some cavities, infections and bone changes may develop without early symptoms. Images may reveal concerns that cannot be seen during a visual examination.
Can I bring X-rays from my previous dentist?
Yes. Ask your previous dental office to transfer available records. Dr. Jafarifar will review their date, quality and coverage before deciding whether additional images are needed.
Can digital X-rays find every cavity?
No diagnostic method detects every problem by itself. Dr. Jafarifar combines X-rays with a clinical examination, your symptoms and other diagnostic tests.
Can dental X-rays show an infection?
They may reveal changes in the bone near a tooth root that suggest infection. The diagnosis also depends on symptoms, examination findings and testing of the tooth.
Will digital X-rays show gum disease?
Images can help evaluate bone loss associated with periodontal disease. Gum measurements, inflammation and other clinical findings are also needed for a complete periodontal assessment.
Should I tell you if I am pregnant?
Yes. Tell our team if you are pregnant or may be pregnant so Dr. Jafarifar can consider the urgency of the concern and determine whether imaging is clinically appropriate.
