If you’ve ever been to the dentist and wondered why you’re being asked to take X-rays—even when your teeth feel fine—you’re not alone. Many patients at Landman Dentistry By the Lake in Mahopac, NY ask: “Do I really need X-rays?” The short answer is yes—and here’s why.
Dental X-rays are an essential diagnostic tool that allows your dental team to see what’s happening beneath the surface. Even the most thorough visual exam can’t catch everything. X-rays help detect cavities, bone loss, infections, and other oral health issues long before they cause pain or visible symptoms.
Let’s break down the importance of dental X-rays, how often you need them, and what types exist.
What Are Dental X-Rays?
Dental X-rays (also called radiographs) are images of your teeth, bones, and surrounding soft tissues that help your dentist identify problems not visible to the naked eye. With these images, we can assess:
● Cavities between teeth or under fillings
● Infections or abscesses at the root
● Bone loss due to gum disease
● Cysts, tumors, or impacted teeth
● Jawbone structure and development
At Landman Dentistry By the Lake, we use digital X-ray technology that emits minimal radiation while delivering fast, high-quality images.
Why Dental X-Rays Are Important
1. Early Detection of Cavities
Tooth decay doesn’t always show visible signs right away. X-rays help us detect cavities in hard-to-see areas—like between teeth or beneath existing dental work—before they progress and require more complex treatment.
2. Monitoring Gum and Bone Health
Gum disease can cause bone loss around teeth. X-rays help us monitor these changes over time, particularly for patients with periodontal concerns.
3. Planning Treatment Accurately
If you need a crown, bridge, implant, or root canal, X-rays help us plan precisely and ensure long-term success.
4. Tracking Development in Children
In pediatric patients, X-rays are essential for monitoring tooth eruption, jaw growth, and detecting potential issues with spacing or crowding.
How Often Do You Need Dental X-Rays?
There’s no one-size-fits-all answer. The frequency of X-rays depends on your oral health history, age, and risk factors. Generally:
● New patients often receive a full set of X-rays to establish a baseline.
● Routine checkups may include bitewing X-rays (showing upper and lower teeth) once a year.
● High-risk patients (with frequent cavities, gum disease, or restorations) may require more frequent imaging.
At Landman Dentistry By the Lake, we tailor your X-ray schedule to your needs—always keeping your safety and comfort in mind.
Are Dental X-Rays Safe?
Yes. Especially with modern digital X-rays, radiation exposure is extremely low—often lower than a short flight on an airplane. For added protection, we always use lead aprons and collars.
We also follow ADA and FDA guidelines to ensure X-rays are used only when necessary. If you’re pregnant or have concerns, please let our team know—we’ll take extra precautions or delay X-rays if appropriate.
Types of Dental X-Rays
● Bitewing X-rays: Show upper and lower teeth in one area; ideal for detecting decay between teeth.
● Periapical X-rays: Show the entire tooth from crown to root; used for root infections or trauma.
● Panoramic X-rays: Capture the entire mouth in one image; helpful for wisdom teeth, jaw disorders, and implant planning.
● Cone Beam CT (CBCT): A 3D imaging scan used for advanced procedures like dental implants or airway assessments.
Common Myths About Dental X-Rays
● “They’re unnecessary if I have no pain.” Many dental problems don’t cause pain until they’re advanced. X-rays help catch issues early.
● “They’re unsafe.” Digital X-rays emit a very low dose of radiation—far less than older film-based systems.
● “My insurance doesn’t cover them.” Most dental insurance plans cover routine X-rays. If you're uninsured, we’re happy to discuss affordable payment options.
