Dental assistants support dentists. They may prepare patients for treatment, sterilize instruments, assist the dentist during procedures, take x-rays, make impressions, and keep dental patient records. Some dental assistants may work in labs. In this program, you’ll be able to take the Ohio Certified Dental Assistant exam and begin working right away – or have the skills you need to continue on in school to become a dental hygienist; some Great Oaks graduates plan to become dentists.
