Teeth - Presentation

The educational presentation on teeth is aimed at enhancing students' understanding of human dentition and the importance of oral hygiene. The learning objectives are to name the different types of teeth, describe their functions in relation to their shapes, and discuss the consequences of inadequate brushing. Through the story of Izzy visiting the dentist, students learn that neglecting to brush teeth, especially after consuming sugary foods, can lead to tooth decay. The dentist, Dr. Roberts, emphasizes the necessity of brushing twice daily to remove harmful bacteria that produce decay-causing acids. The session also covers the various types of teeth: incisors for cutting, canines for tearing, and premolars and molars for crushing food, highlighting the challenges of eating with missing teeth.

Students are encouraged to engage in interactive activities such as researching and labeling diagrams of different teeth, understanding their functions, and experimenting to see what stains teeth. The presentation explains the composition of teeth, mainly calcium and phosphorous, and the role of toothpaste and fluoride in cleaning and repairing the 'shell' of teeth. Additionally, the lesson includes a practical demonstration using Plaque Reveal tablets to show the effectiveness of brushing in removing plaque, a film of bacteria that can cause tooth decay. By the end of the lesson, students should be able to articulate why brushing teeth at least twice a day is essential for preventing dental problems and maintaining overall oral health.
