More Than A Century of Storied History And Innovation Leadership

For more than a century, DENTSPLY and Sirona have set a global standard for dental manufacturing, technology development, digital treatment and clinical education. Throughout our history, we have been at the forefront of innovation to improve and advance dentistry.

Dentsply Sirona traces its roots to humble beginnings – DENTSPLY International was founded as Dentists’ Supply Company in 1899 in New York City and the company that became Sirona Dental Systems was founded in 1877 in Erlangen, Germany. Through our transformative merger in 2016, Dentsply Sirona has grown to become the world’s largest manufacturer of professional dental products and technologies. With approximately 15,000 employees, operations in more than 40 countries worldwide and a sales presence in more than 120 countries, Dentsply Sirona provides a comprehensive end-to-end solutions offering of dental and oral health products to dental professionals. Our customers and their patients around the world depend on Dentsply Sirona for innovative, high-quality and effective solutions to advance oral health and deliver better, safer and faster dentistry.

Throughout the last century as separate companies, DENTSPLY and Sirona have each invested significantly in innovation, new product development and the broadest clinical education platform in the industry. We both recognized early on that the advantages of digitization are not in the individual device, but in the seamless interaction of hardware, software and devices creating an innovative solution for dental practitioners and dental patients. Our recent innovations build upon the efforts of our visionary founders to integrate all aspects of oral healthcare, enabling dental professionals to better devote themselves to serving patients. Together, Dentsply Sirona continues that tradition of strong research and development and clinical education, and remains at the forefront of driving progress in dentistry.
