Best dentist in Chennai | Why Are Dental X-Rays Necessary? Dental X-rays are essential for diagnosing issues that are not visible during a regular exam. They help detect cavities, bone loss, impacted teeth, and infections at an early stage, enabling timely treatment. X-rays also guide dentists during procedures like root canals and implants. Modern X-rays use minimal radiation, making them safe for patients. At Dr. Akkshaya Dental & Aesthetics, we utilize advanced X-ray technology to ensure precise and effective care for your oral health.
