Dental X-Ray: Importance, Types, Procedure, Safety & Cost – Complete Guide
Dental health is not only about brushing, flossing, and avoiding sweets — it also requires accurate diagnosis of what is happening inside the teeth, gums, and jawbone. Many dental problems are not visible to the naked eye, and that’s where Dental X-Ray plays an important role.
This blog explains everything you need to know about Dental X-Rays, including types, safety, test preparation, benefits, and price range.
What is a Dental X-Ray?
A Dental X-Ray (also called Intraoral X-Ray) is a diagnostic imaging technique used to visualize the internal structure of teeth, gums, jawbone, and surrounding tissues. It helps dentists diagnose hidden dental problems like cavities, infections, bone loss, impacted teeth, cysts, and tumors.
Most modern clinics and diagnostic centers now use Digital Dental X-Ray which offers faster, clearer, and low-radiation imaging.
Why Are Dental X-Rays Needed?
Dentists may recommend a dental X-ray if you experience any of the following:
✔ Toothache or sensitivity
✔ Gum bleeding or swelling
✔ Tooth decay or cavity
✔ Wisdom tooth pain
✔ Jaw pain or clicking sound
✔ Post-root canal, implant or extraction
✔ Dental trauma / injury
✔ Before orthodontic treatment (braces & aligners)
Dental X-Rays help identify problems early, reducing the need for expensive treatments.
Types of Dental X-Rays
1️⃣ Intraoral X-Rays (Most common)
