·
Tell the students that milk

·
Explain the basic structure
of a permanent tooth (root and crown) by drawing it on the board and ask the
students to see the diagram from book.
·
Demonstrate the shapes and
locations of incisors, canines, premolars and molars by using charts, pictures
or drawing.
·
Show the students a picture
of full jaw in which all types of teeth are shown and ask to count the number
of each type of teeth in the diagram.
·
Prepare teeth card (like the
one shown) to clear the types of teeth and reinforce students’ learning by
asking them to locate incisors, canines, premolars and molars.
·
Inform them that they will
study further about the teeth in next lesson where they will discuss the common
disorders of teeth and the importance of their hygiene.
Sum up / Conclusion
·
There are two types of teeth: milk teeth and
permanent teeth. Permanent teeth are of four types: incisors, canines,
premolars and molars.
