EFDA Expanded Function · Dental Board Approved
Learn Today's Coronal Polishing course is a hands-on, dental board approved Expanded Function Dental Assistant (EFDA) certification designed for dental assistants in Oklahoma and Missouri. Upon completion, participants are certified to perform coronal polishing procedures as part of a dental team under the direct supervision of a licensed dentist — expanding both their scope of practice and their value to any dental office.
Coronal polishing is one of the most sought-after expanded functions for dental assistants in Oklahoma. It allows trained and certified EFDAs to remove extrinsic stain and soft deposits from the coronal surfaces of teeth — a procedure that directly supports patient care and keeps the hygiene schedule running efficiently. Dental offices that employ EFDA-certified assistants consistently report improved workflow, higher patient satisfaction, and better team productivity.
Brook Gibson, RDH, brings over 20 years of clinical dental hygiene experience to this course — ensuring every participant leaves with practical, chairside-ready skills. Classes are intentionally kept small so that every student receives direct, individualized instruction and adequate hands-on clinical practice time. Learn Today can deliver this course at your dental office or at a scheduled classroom location in Oklahoma or Missouri.

In Oklahoma and Missouri, dental assistants are not legally permitted to perform coronal polishing without a current EFDA certification from a dental board approved course. Performing this procedure without proper certification puts both the assistant and the supervising dentist at legal and regulatory risk. Learn Today's course meets all state dental board requirements and provides the documentation needed for license compliance.
Beyond compliance, EFDA certification in coronal polishing is a genuine career investment. Certified dental assistants earn higher wages, qualify for expanded roles, and are more attractive candidates in a competitive job market. Many dental offices in Tulsa, Oklahoma City, and across Missouri actively seek EFDA-certified assistants — making this certification one of the fastest returns on a dental assistant's professional development.
This is a hands-on, clinical course — students practice coronal polishing on each other. To participate as a patient, students need at least 20 natural teeth free of crowns, fixed bridges, and orthodontic buttons, and should not have had a professional cleaning within one week before the course. Students who do not meet those criteria — or prefer not to be practiced on — should arrange to bring a qualified practice patient. Clinical scrubs are required.
All students will also complete an exam on a separate patient. Your exam patient cannot be another dental professional. The course includes a practical skills assessment as well as written examination components. Upon successful completion, Learn Today provides the documentation you need to submit your EFDA permit to the Oklahoma Board of Dentistry.
