Sonendo

Sonendo is a privately-held medical device company focused on the dental space with its market-leading device “GentleWave” that has transformed the treatment of root canals for patients, physicians, and their practices.


Sonendo is an innovative medical device company focused on transforming the dental market, starting with its initial focus on improving upon the traditional root canal procedure. The company’s first marketed product is the GentleWave system, a 510(k)-cleared device indicated for the preparation, cleaning, and irrigation of teeth during root canal therapy. Through a proprietary combination of technologies for de-gassing liquids and creating high-speed fluid dynamics within the root canal, the GentleWave system is able to dissolve tissue faster and clean the root canal more thoroughly than conventional treatments, in turn leading to fewer root canal failures, improved efficiency for physicians, and superior outcomes for patients.
