The support for the argument comes from looking at tooth enamel, which dries out when it isn't kept hydrated by lips. While modern day reptiles like crocodiles have the kind of exposed teeth we tend to imagine on dinosaurs, crocodiles spend most of their day in the water, which helps keep the enamel hydrated. Dinosaurs, however, were mostly terrestrial.
The study concluded that the teeth "were not exposed permanently, but covered by reptilian lips," like those on some lizards.
