St. Columba's preschoolers are learning about the importance of dental care. One of the more important dental care lessons they learned was flossing. Mrs. John, our preschool teacher, brought in ice cube trays for the students. In between the ice cube mold, she placed black play-doh. The students were then given floss to clean the bad stuff out between their teeth. Pictured here cleaning away is preschooler Charlotte Carney.
