An endodontic assistant works with a specialized dentist called an endodontist. An endodontist treats problems with the tissues and pulp within the teeth. The primary dental procedure they perform is a root canal. In this job, your duties are to assist the endodontist in their practice and procedures. Your responsibilities may include scheduling patient appointments, performing x-rays, and assisting before, during, and after a root canal. During these procedures, you may clean the patient’s mouth, pass tools to the dentist, or monitor the patient’s wellbeing and comfort.
