Common Types of Dental X-Rays (And Why You Need Them!)

A healthy smile depends on more than what you can see in the mirror. Many dental problems hide beneath the surface, in places only an X-ray can reveal. Restoration Dental can use X-rays to catch issues early, protect your oral health, and help you keep your natural teeth for years to come. We’ve compiled this guide to highlight why we take dental X-rays and what each type shows.

What Are Dental X-Rays and Why Are They Important?

Dental X-rays are images that show what’s happening inside your teeth, gums, and jawbone. They let your dentist see things that aren’t visible during a regular exam, such as decay between teeth, bone loss, or problems with a tooth’s root. Without X-rays, many dental issues would go unnoticed until they became painful or serious. Catching problems early means simpler, more affordable treatment. It also means protecting your natural teeth for as long as possible.

Common Dental X-Rays Types

There are several types of dental radiographs, each serving a different purpose. The most common types include:

  • Bitewing X-Rays – These show the upper and lower back teeth as they bite together. They’re great for spotting cavities between teeth and checking bone levels.
  • Periapical X-Rays – These capture the entire tooth, from crown to root, along with the surrounding bone. They help identify issues below the gumline, like infections or abscesses.
  • Panoramic X-Rays – These provide a wide view of the entire mouth in a single image, including the teeth, jaws, and sinuses. They’re often used to plan treatments like braces, dental implants, and wisdom teeth removal.
  • Occlusal X-Rays – These show the roof or floor of the mouth and help track tooth development in children or locate extra teeth.
  • Cone Beam CT (CBCT) Scans – These create detailed 3D images of your teeth, jaw, and facial structures. They’re often used for complex procedures like implant placement.

What Can Dental X-Rays Detect?

Dentists rely on dental X-rays for cavities, but they can also help detect:

  • Cavities Between Teeth – These small areas of decay are often invisible to the naked eye.
  • Bone Loss – This can be a sign of gum disease.
  • Infections or Abscesses – These often develop below the gumline.
  • Impacted Teeth – Wisdom teeth are common examples.
  • Cysts or Tumors – Early detection allows for prompt treatment.
  • Developmental Issues – This is especially important for growing children.

How Often Do You Need Dental X-Rays?

How often you need dental X-rays depends on your age, oral health, and risk factors. Most patients require X-rays once a year, but that can vary from person to person. Children often need X-rays more frequently because their teeth and jaws are still developing. Adults with a history of gum disease, cavities, or other dental issues may also need more frequent imaging. Meanwhile, patients with excellent oral health and no history of problems may only need X-rays every couple of years.

Are Dental X-Rays Safe?

Dental X-rays use very low levels of radiation, and modern technology has made them even safer than in the past. Digital X-rays, which we use at Restoration Dental, produce less radiation than traditional X-rays. We also provide protective gear, such as lead aprons, to minimize exposure. The benefits of catching dental problems early far outweigh the minimal risks involved with dental X-rays.

FAQ About Dental X-Rays

Do I Need Dental X-Rays for Teeth at Every Dental Appointment?

Most patients only need X-rays once a year. However, your dentist may recommend them more often if you have a history of dental issues or are undergoing treatment.

Can Dental X-Rays Find Cavities Between My Teeth?

Yes. Bitewing X-rays are especially good at finding cavities between teeth, which are often impossible to see during a visual exam.

Which Dental X-Rays Show the Whole Mouth?

Panoramic X-rays capture the entire mouth in one image, including the teeth, jaws, and sinuses. This makes them useful for planning treatments like braces or implants.

How Long Does a Dental X-Ray Take?

Most dental X-rays take just a few minutes. Digital X-rays are particularly quick, often producing images within seconds.
