Confused about dental X-rays? Discover their types, benefits, and how they detect cavities, infections, and bone loss. Find out which X-ray suits you best!
Dental X-rays are essential for diagnosing oral health issues that may not be visible during a routine examination. These images help detect cavities, bone loss, infections, and other concerns at an early stage. However, not all X-rays serve the same purpose - there are different types, each designed for specific diagnostic needs.
This guide provides an overview of the various dental X-ray types, their uses, and how to determine which one is suitable for you.
Dental X-rays, or radiographs, use low-dose radiation to capture detailed images of your teeth, gums, and jawbone. These images allow dentists to identify potential problems before they become serious, ensuring timely and effective treatment.
These are the most commonly used dental X-rays, offering detailed images of individual teeth.
Purpose: Identify cavities between teeth and monitor bone loss.
How It Works: The patient bites down on a film or digital sensor while the X-ray captures images of the upper and lower teeth in one mouth area.
Purpose: Capture the full length of a tooth, from the crown to the root, including the surrounding bone.
How It Works: This X-ray focuses on one or two specific teeth at a time.
Purpose: Provide an image of the entire arch of teeth (upper or lower jaw) in a single shot.
How It Works: The X-ray film is placed inside the mouth to capture the image.
These X-rays offer a broader perspective of the jaw, skull, and surrounding structures.
Purpose: Provides a comprehensive mouth view, including the teeth, jaw, and sinuses.
How It Works: The X-ray machine rotates around the patient's head to capture the image.
Purpose: Assesses the side profile of the skull and jaw.
How It Works: The X-ray is taken from the side of the head.
Purpose: Provides a 3D image of teeth, nerves, and bone structures.
How It Works: Utilizes advanced technology to create detailed cross-sectional images.
