An oral dilator includes a first body, a second body, a rotary member, and a positioning member. The first body includes a housing and a first duckbilled element. The second body includes a second duckbilled element corresponding to the first duckbilled element. The rotary member drives the second body to rotate. The positioning member is on the first body and selectively locks or unlocks the relative position between the first duckbilled element and the second duckbilled element when the second duckbilled element is driven to rotate by the rotary member.
