Dental X-rays are one of the best tools dentists have to look after your oral health. But if you’ve ever heard terms like “bitewing” or “panoramic,” you might wonder — which dental X-ray do you actually need?
At Howick Dental Surgery, we believe patients deserve to understand the “why” behind every dental recommendation. So here’s a simple guide to the main types of dental X-rays, and which might be right for you, depending on your dental needs.
1. Bitewing X-Rays: Checking Between Teeth
Best for: Detecting cavities between teeth and checking bone levels around your gums.
Bitewing X-rays capture the upper and lower teeth in one small area of your mouth. They’re commonly used during routine check-ups, especially if you’re prone to decay or have a history of fillings. If you live in Howick and visit us regularly for exams, chances are you’ve already had a few bitewings taken!
2. Periapical X-Rays: Focusing on One Tooth
Best for: Finding problems deep within a specific tooth, including the roots or surrounding bone.
If you’re experiencing tooth pain or your dentist suspects an infection, a periapical X-ray zooms in on the entire tooth, from crown to root tip. It’s essential for diagnosing abscesses, fractures, or issues below the gumline that aren’t visible during a normal exam.
3. Panoramic X-Rays: Seeing the Big Picture
Best for: Assessing wisdom teeth, jaw joints (TMJ), and overall bone health.
Panoramic X-rays capture your entire mouth in one sweeping image. At Howick Dental Surgery, we often use them for planning wisdom tooth removal, checking for cysts or tumours, or evaluating bone levels for dental implants. They’re quick, painless, and help us see how everything fits together.
4. OPG X-Rays: Similar to Panoramic
In New Zealand, you’ll sometimes hear “OPG” used instead of “panoramic.” It stands for “Orthopantomogram.” It’s essentially the same scan — giving your dentist a broad look at your jaws, teeth, and sinus areas all at once.
5. CBCT Scans: 3D Precision
Best for: Complex cases needing precise planning, like implants or root canals.
Cone Beam CT (CBCT) scans provide a 3D view of your teeth, nerves, and bone. While not used for every patient, they’re invaluable when a high level of detail is required.
So, Which X-Ray Do You Need?
It depends on your specific dental concerns. Regular check-ups might involve bitewings, while pain or swelling could call for a periapical or panoramic X-ray. At Howick Dental Surgery, we’ll always discuss the best option for you and explain why it’s needed.
