Some Harker preschoolers had big smiles yesterday, as they enjoyed a lesson on dental hygiene from one of our parents, Dr. Becky Gong, D.D.S. Students learned why it’s important to go to the dentist, how much toothpaste to use, how long and how often to brush one’s teeth, how cavities are formed and much more. The students even got to practice their own tooth-brushing skills on a dinosaur friend. Furthermore, every child was given a bag of dental goodies to take home. It is wonderful to have parents come share their expertise with the students!
