Dental X-Rays also known as radiographs is now a crucial part of any dental treatment. This diagnostic tool helps dentists detect diseases and show cavities, bones loss or hidden dental structure which otherwise cannot be detected in a visual examination.
Why dental X-rays are done?
1. Find problems like tooth decay, bone damage supporting the teeth.
2. Detect cysts, abscesses, tumors
3. Planning treatment for extensive root canal surgery, dental implants, cavities and complicated tooth removal
4. Orthodontic treatment
5. Teeth that do not break through the gum perfectly.
Categories of X-rays
