If you’ve ever wondered, “How often should I get dental X-rays?”—you’re not alone. It’s one of the most common questions patients ask during routine exams. Dental X-rays play a key role in identifying problems you can’t see in the mirror, from tiny cavities between teeth to early signs of bone loss or infection.
The good news? X-rays aren’t something you need at every visit. How often you need them depends on your oral health history, your current condition, and your dentist’s assessment. In this post, we’ll break down how often dental X-rays are typically recommended, what influences that schedule, and why they matter more than you might think.
At Elizabeth L. Wakim DDS, we use low-radiation digital imaging to make every diagnostic step safer, faster, and more precise. During your visit, we’ll take the time to assess your individual needs and recommend only the X-rays that support your long-term oral health.
Why Dental X-Rays Matter
Dental X-rays are more than just routine—they’re a critical part of preventive care. In the U.S. alone, an estimated 1.4 billion dental X-rays are performed each year, reflecting how essential they are in everyday dentistry. These images allow your dentist to spot problems that aren’t visible during a standard visual exam, such as:
- Cavities forming between teeth
- Bone loss linked to gum disease
- Infections at the root or below the gum line
- Impacted teeth or changes in tooth alignment
Without X-rays, these issues could go unnoticed until they become painful—or more difficult to treat. Early detection means earlier intervention, often saving you time, money, and unnecessary discomfort in the long run.
Even if your teeth feel fine, regular X-rays help confirm that your smile is healthy beneath the surface.
How Often Should You Get Dental X-Rays?
Dental X-rays aren’t always needed at every checkup—and the type of X-ray your dentist recommends depends on your oral health, history, and risk level. Here’s a breakdown of the most common types:
Bitewing X-Rays
Shows the upper and lower back teeth in one view to detect cavities between teeth and monitor bone levels.
How often: Every 12–24 months for low-risk adults; every 6–12 months for high-risk patients or children prone to decay.
Used for: Detecting early decay, monitoring fillings, and checking for signs of bone loss.
Captures the entire tooth from crown to root, including the surrounding bone.
How often: Taken as needed when there’s pain, infection, or deep decay suspected.
Used for: Diagnosing abscesses, fractures, or issues at the root level
Panoramic X-Rays
Provides a wide-angle view of the entire mouth, including all teeth, jawbones, sinuses, and surrounding structures.
How often: Usually every 3–5 years, or when evaluating major changes like wisdom teeth, jaw alignment, or orthodontic needs.
Used for: Checking tooth development, impacted teeth, TMJ issues, and planning treatment for braces or extractions.
Full-Mouth Series (FMX)
A complete set of X-rays, typically combining multiple periapical and bitewing images for a full look at every tooth.
How often: Typically every 3–5 years, especially for new patients or those with a history of dental problems.
Used for: Comprehensive assessment of all teeth and supporting bone structure.
What Affects Your X-Ray Schedule?
While there are general guidelines, how often you need dental imaging depends on your individual risk factors and oral health history. Most dentists personalize your X-ray schedule based on the following:
1. Cavity Risk and History of Decay
If you’ve experienced dental decay, frequent fillings, or extensive decay, you may need intraoral X-rays more often. These images help your dentist detect cavities between the upper and lower teeth, where problems often go unnoticed during a visual exam. In fact, research shows that nearly half of the global population is affected by tooth decay, making early detection through imaging a key part of preventive care.
2. Gum and Bone Health
Signs of oral disease, such as bleeding gums, bone loss, or periodontal disease, may require X-rays every 6 to 12 months. These scans show changes in the bone surrounding the teeth and help monitor gums healthy enough to support optimal oral health.
3. Age and Stage of Development
Children and teens typically need more frequent mouth X-rays to track developing teeth and jaw growth. Older adults, especially those with bone density loss or receding gums, may also benefit from closer monitoring.
4. New Patient Exams
During a first visit to a dental practice, your provider may order a full-mouth series to establish a baseline. This is especially important if there’s no recent record of dental X-rays or a complete medical and dental history.
5. Ongoing Symptoms or Dental Work
If you’ve had procedures like a dental implant, root canal, or crown, your provider may use targeted X-rays such as a periapical X-ray to check the treated tooth and surrounding bone structure. Persistent pain, swelling, or signs of infection may also call for immediate dental treatment supported by precise imaging.
Your dentist’s recommendation will always reflect your personal health history—not just a checklist. That’s why regular checkups are so important: they help fine-tune your care, including when X-rays are truly needed.
Are Dental X-Rays Safe?
Yes—dental X-rays are safe when used appropriately. Modern X-ray machines used in most dental offices rely on digital technology that produces very low levels of ionizing radiation, especially when compared to earlier methods. The radiation exposure from a typical image is minimal—often equal to or less than a day of natural radiation from your environment.
Dentists follow established radiation safety guidelines, including protective measures like thyroid collars and lead aprons when appropriate. These precautions help shield areas of the body while still allowing clear views of all the teeth, surrounding bone, and structures that aren’t visible in a standard exam.
The American Dental Association and experts in oral and maxillofacial radiology recommend imaging based on your medical and dental history, risk of tooth decay or dental disease, and upcoming dental treatment plans. That means you’re only exposed when X-rays are truly needed—and the benefit clearly outweighs any radiation risk.
There are several types of dental X-rays, including periapical X-rays, which show the entire tooth and root; occlusal X-rays, which capture the floor or roof of the mouth; and extraoral X-rays like CT scans, which may be used to assess more complex conditions. Each plays a specific role in helping your dentist diagnose or monitor conditions like dental decay, bone loss, or infections.
When used judiciously—not as frequent X-rays without reason—dental imaging is a safe, essential tool that allows your provider to detect problems early, plan effective treatments, and help you maintain healthy teeth and long-term oral health.
Still Unsure? Ask Your Dentist
If you’re not sure how often you need X-rays—or whether you need them at all—your best source of guidance is your dentist. Imaging decisions aren’t one-size-fits-all. They’re based on your medical and dental history, current risk level, and any signs of developing issues.
A dentist who knows your background can tailor your dental imaging schedule to avoid unnecessary exposure while still catching problems early. These decisions often change over time, depending on your age, health status, and recent findings.
That’s why it’s important to keep up with regular dental exams. They’re not just for cleanings—they’re a chance to update your care plan and decide when X-rays are truly necessary to support your long-term oral health.
