Who is allowed to practice dentistry without a license?

The option stating that students of reputable dental schools performing operations without pay is correct because dental schools often have programs that allow students to gain practical experience under the supervision of licensed professionals. This hands-on training is an essential part of their education, and while they may be performing procedures, they are doing so in a controlled environment where they are guided and overseen by licensed faculty members. This arrangement is legally permissible as it is part of their educational curriculum.

The other options do not accurately reflect the legalities surrounding the practice of dentistry. Licensed dental hygienists can perform specific tasks and services, but they must still operate within the confines of their licensure and cannot perform all dental procedures independently. Health care workers from different fields are not permitted to perform dental procedures unless they are properly licensed to do so. Finally, individuals practicing in other states must also hold valid licensure for the state in which they are providing services; practicing without a license in a different state is not legally allowed.
