Dental X-rays are images that allow observing internal structures of teeth, gums, and bones that cannot be seen with the naked eye during a clinical examination. Thanks to them, dentists can detect hidden problems, plan treatments with precision, and care for your oral health more completely.

With modern digital equipment that emits low radiation doses and provides immediate results, safety and comfort for patients are guaranteed.

Why are dental X-rays important?

X-rays are a fundamental tool for diagnosis and prevention. They allow identifying conditions such as:
• Hidden cavities between teeth.
• Bone loss caused by periodontal disease.
• Retained or forming teeth, especially in children.
• Problems in tooth roots or nerves.
• Alterations in bite or temporomandibular joint (TMJ).

Without an X-ray, many of these problems could go unnoticed until causing pain or major complications.

Most common types of dental X-rays

Different types of X-rays are used according to each patient's needs:

Periapical X-ray: shows a complete tooth, from crown to root.
Panoramic X-ray: allows seeing all teeth and jawbones in a single image.
Bite-wing X-ray: ideal for detecting cavities between posterior teeth.
Occlusal X-ray: used to observe unerupted teeth or broader bone structures.

Each type fulfills a specific function and helps plan treatments like orthodontics, endodontics, or dental implants.

How often should they be performed?

Frequency depends on age, clinical history, and oral health status of each person. Generally, specialists recommend performing X-rays once or twice a year, or before starting important treatments.

In children, they help control growth and dental eruption; in adults, they allow evaluating the state of roots, bones, and restored pieces.

Safety in digital X-rays

With digital X-rays, a modern technology that reduces radiation exposure by up to 90% compared to traditional methods. Additionally, lead aprons and special protectors are used to provide safe care, even for children and pregnant women (according to specialist evaluation).
