Dental X-rays are a vital part of preventive care, helping your dentist spot problems that can’t be seen during a visual exam — like cavities between teeth, bone loss, or infections beneath the surface.
But how often should you actually get them?
The short answer: It depends on your individual risk level, age, and dental history. Your dentist will recommend an X-ray schedule based on what’s best for your long-term oral health.
🗓 Recommended Dental X-Ray Frequency (General Guidelines)
Here’s a look at typical dental X-ray schedules — though your dentist may adjust this based on your specific needs:
👩⚕️ Adults with Healthy Teeth & Gums
- Every 12–24 months for bitewing X-rays (to check between teeth)
- Full-mouth X-rays may be taken every 3–5 years
🧒 Children & Teens
- Every 6–12 months if they are prone to cavities
- X-rays help monitor developing teeth, spacing, and jaw growth
😬 Patients with a History of Decay, Gum Disease, or Dental Work
- Every 6–12 months, or more frequently if you:
- Have had recent cavities
- Are at risk for gum disease
- Wear braces, bridges, or implants
- Have dry mouth or other risk factors
🦷 New Patients
Your first visit may include a full set of X-rays to establish a baseline, especially if your previous records are unavailable.
🔍 Why You Might Need X-Rays More Frequently
Your dentist may recommend more frequent X-rays if you:
- Experience unexplained pain or swelling
- Have visible signs of infection or trauma
- Are starting a treatment plan like root canal therapy or orthodontics
- Are being monitored for bone loss or wisdom tooth development
💡 Can I Refuse X-Rays?
Yes — you always have the right to decline. But it’s important to know that X-rays help detect problems before they become painful or expensive to fix. Without them, your dentist is limited in what they can see — and this could delay important treatment.
We’ll always explain why an X-ray is recommended and answer any questions you may have.
☢️ Are X-Rays Safe If Taken Regularly?
Yes — especially with digital X-rays, which use up to 90% less radiation than traditional film.
Your dentist follows strict safety protocols and only takes X-rays when truly necessary, based on the ALARA principle (As Low As Reasonably Achievable).
Final Thoughts
There’s no one-size-fits-all answer when it comes to dental X-rays — and that’s a good thing. Your dentist will tailor the frequency to your unique needs, balancing early detection with minimal exposure.
