If you want to be able to do as many things as possible as a dental assistant, you’ll have to level up! Working under a dentist’s supervision, a dental assistant performs various tasks before and after the dentist and client meet during appointments.
They are responsible for assisting dentists during procedures, taking X-rays, sterilizing dental instruments, and educating patients on maintaining oral health. However, dental assistants’ list of responsibilities is divided between level I dental assistants and level II assistants.
While the idea of there being two levels of dental assistants may seem confusing at first, there are pretty straightforward differences between them in what they can and can’t do. Here are some of the biggest factors distinguishing level I and level II dental assistants from each other.

The Duties and Capabilities of a Level I Dental Assistant
Level I Dental Assistants, often called ‘chairside assistants,’ play a crucial role in dental practices. Their responsibilities include preparing and seating patients, sterilizing instruments, managing inventory, and processing X-rays. They prepare dental materials, make cast models, and maintain patient charts.
Furthermore, they are trained to recognize emergency signs and are proficient in CPR and First Aid.

What a Level II Assistant Can Do That a Level I Assistant Cannot
A Level 2 assistant can handle all tasks of a Level 1 assistant and more, as taught in dental assistant school. Their unique duties include mechanical coronal tooth polishing, applying pit and fissure sealants, and using anti-cariogenic agents to prevent tooth decay. They apply topical anesthetics, which are beyond the scope of entry-level dental assistants.
Additionally, Intra-Oral Dental Assistants are qualified to take impressions for study models, expose radiographs, and administer desensitizing agents. Level II intra-oral dental assistants may perform advanced tasks like oral irrigation and polishing restorations. Their training often includes more comprehensive schooling, especially in provinces like Ontario, where Level 2 dental assistant duties are strictly regulated to ensure superior patient care.
