St. Renatus, LLC was founded to develop a revolutionary innovation – the world's first dental anesthetic administered through the nasal cavity, designed for use in procedures involving most of the upper teeth, with a goal of gaining FDA approval to commercialize and distribute. The company's name comes from the patron saint of anesthesia and has Latin roots meaning new beginning.
St. Renatus believes the benefits of its product will provide a better experience for doctors and qualifying patients. These benefits could include an accurate and sophisticated method to anesthetize the upper teeth topically, without the risk, fear, and pain of an injection. Patients would not experience the uncomfortable cheek or "fat lip" numbness associated with the needle.
