Third-graders in Christina Delaney's class at South Bay Elementary School learned some important oral hygiene tips during a recent workshop with representatives from Lindenhurst Orthodontics.  The representatives focused on discussing the difference between a dentist and an orthodontist and the reasons you would need to consult an orthodontist. The comprehensive program reminded students about the proper way to brush and floss, as well as the importance of limiting sweets, helpful reminders as trick-or-treating approaches.
