Intraoral X-rays

• A. are the most common type of x-ray, they give a high level of detail of the tooth, bone and supporting tissues of the mouth
• B. are only for orthodontics
• C. are used to image the whole skull
• D. only show gums

Answer: (A)

Intraoral X-rays are the everyday workhorse in dental imaging because they capture high-detail images of a tooth or a small group of teeth along with the surrounding bone and periodontal structures. Placed inside the mouth, these small images give excellent spatial resolution, making them ideal for detecting early caries, assessing root anatomy and periapical areas, and evaluating bone levels for periodontal health. That combination of detail, targeted view, and versatility (including bite-wing and periapical images) is why they’re the most commonly used type of dental X-ray.

They’re not limited to orthodontics, and they do not image the entire skull—that’s what extraoral views like panoramic radiographs are for. They also don’t merely show gums; the primary focus is on teeth and the supporting hard tissues around them, with soft tissue outlines being incidental.

So the best description is that intraoral X-rays provide detailed views of teeth, bone, and supporting tissues inside the mouth, which is why they are the most common type.
