The Registered Dental Hygienists employed at the Marshall County Health Department work in the Marshall County Schools, grades one through six, to educate and instruct the students on proper brushing technique. They supervise the students through a “brushing” exercise held in each classroom. This is done in conjunction with a dental health presentation, followed by an oral health assessment of each student. Flossing instructions are given to fifth graders during the presentation. Six graders receive additional training on what to do in the event of a dental emergency.
