As an entry-level dental assistant, you have numerous responsibilities in a dental office. You primarily focus clerical and administrative duties, such as scheduling patients for appointments, filing medical records, filling out billing invoices and insurance reimbursement forms, and ensuring that the office inventory is adequate. However, you also have clinical duties in which you assist the dentist with routine tasks. You sterilize tools, prepare the exam rooms, provide suction during teeth cleaning and other procedures, help make the patients comfortable, conduct simple lab tests, and take x-rays and process them.
