You may have been surprised when your dentist recommends an X-ray during a routine check-up, especially if you only came in for a cleaning. While it might seem unexpected, dental X-rays are essential for spotting hidden issues that can’t be seen during a visual exam. Modern digital X-rays use very low levels of radiation, far less than traditional film-based methods, and are safe even for children and pregnant women.
What do dental X-rays show? Dental X-rays (radiographs) allow dentists to examine areas beneath the gums, between teeth, and within the jawbone.
They can reveal:
- Cavities between teeth
- Signs of gum disease
- Infections or abscesses
- Bone loss in the jaw
- Buried or impacted teeth
- Cysts, tumors or other abnormalities
Types of dental X-rays: Common X-ray types include:
- Panoramic: Shows the entire mouth in one image.
- Periapical: Focuses on one or two teeth from root to crown.
- Bitewing: Captures upper and lower back teeth, helpful for spotting decay between teeth.
- Cephalometric: Side profile of the head, often used in orthodontic planning.
- Cone Beam CT: Produces 3D images for complex procedures like dental implants or jaw surgery.
