What Are the Allowable Duties of a Dental Assistant
Specific laws and regulations exist that clearly and explicitly define the duties that a Dental Assistant (DA) is allowed to perform. As mentioned within these specifications, there is also the level of dentist supervision required, as well as the setting where these duties can complete.
Do keep in mind that it’s considered a criminal offense to perform any function that is not part of their duties. It can be grounds for license discipline for both the assistant performing the illegal actions, as well as for the person who aids or abets this activity.
