Dr. R.A.D. Jeewantha stands today as one of Sri Lanka's most forward-thinking and respected dental professionals — a clinician whose name has become synonymous with precision, innovation, and compassionate care.
His academic foundation was laid at the prestigious University of Peradeniya, where he earned his Bachelor of Dental Surgery from the Faculty of Dental Sciences. From the outset, Dr. Jeewantha distinguished himself through a deep commitment to mastering both the science and artistry of dentistry. Upon graduation, he served as a dental surgeon in several government hospitals, gaining broad clinical exposure and refining his expertise in treating a wide spectrum of dental conditions.
His tenure at Karapitiya Teaching Hospital and Nawaloka Hospital proved pivotal. Working within these esteemed institutions, he managed routine cases and complex procedures alike, sharpening his clinical judgment and strengthening his dedication to patient-centered care. These experiences formed the bedrock of the high standards he would later establish in private practice.
Driven by a vision to deliver world-class dentistry within Sri Lanka, Dr. Jeewantha founded Doctor J Premium Dental Care in Delkanda, Nugegoda. This state-of-the-art facility reflects his philosophy that patients deserve access to advanced technology, modern methodologies, and internationally benchmarked treatment protocols without leaving their homeland.
"Every patient deserves world-class dental care without leaving their homeland. My mission is to bring the best of global dentistry home to Sri Lanka."
A defining milestone in his professional development was the successful completion of the American Residency Course in Dental Implantology at Roseman University of Health Sciences, accredited by the American Academy of Implant Dentistry. This rigorous 150-hour programme — encompassing extensive hands-on and clinical training — equipped him with the refined expertise required for intricate implant procedures.
His commitment to professional advancement is further evidenced by his distinguished fellowships. As a Fellow of the International College of Continuing Dental Education (FICCDE), he has demonstrated unwavering dedication to continuous learning and global best practices. In 2024, he was inducted as a Fellow of the Pierre Fauchard Academy (USA), a prestigious honour recognising his significant contributions to the advancement of dentistry worldwide.
Dr. Jeewantha's expertise extends deeply into advanced endodontics, where he has mastered modern root canal shaping protocols and the application of Mineral Trioxide Aggregate (MTA) in both surgical and non-surgical treatments. His meticulous techniques minimise patient discomfort while ensuring long-term success and durability of treatment outcomes.
