So the navy is now providing dental services to the public?
The dentists are part of the ship's complement. There are dental emergencies that can require hospitalization. As dentists in CO are banned from performing work until at least the 17th of April, and turn over their PPE to the state, it is likely the same in NY. So, yeah, the dentists on the ships will likely be performing dental services for the public that aren't COVID-19 positive that are in need of the aforementioned emrgency services.
