After cleaning a patient’s teeth or performing a procedure, it is the dental assistant’s job to clean up the carts, tables, chairs, and counters. You’ll collect all of the used hand pieces and drop them off in the clinic’s ultrasonic cleaner to begin the sterilization process. After cleaning up a room, you will set it up for the next appointment. After the last appointment, you’ll close the room by wiping down the chairs, carts, and counters once more and performing other deep cleaning routines. Most clinic’s floors, windows, and trash will be cleaned by an after-hours crew, so you won’t need to worry about cleaning the entire clinic; just the expensive equipment you have been entrusted with.
