Which of the following is NOT a suitable activity for a dental assistant?

The extraction of teeth is a procedure that is reserved for licensed dentists. Dental assistants do play crucial roles in a dental practice, but their scope of practice does not include performing invasive procedures such as tooth extractions. This activity requires specialized training and licensure that dental assistants do not possess.

In contrast, applying topical anesthetics under supervision, changing bleach pellets, and performing dental sealants are activities that fall within the appropriate scope of practice for a dental assistant, especially when conducted under the indirect supervision of a licensed dentist. These tasks do not involve invasive procedures and are commonly delegated to dental assistants, allowing for an efficient workflow in a dental setting.
