Objective: Children will explore their teeth, discover how they work, and learn about how a dentist helps keep teeth healthy.‹ Return to Theme
In our early years, humans have 20 teeth. Around the age of 5 or 6, our adult teeth begin to emerge and replace our “baby teeth”. Adults have 28 permanent teeth (32 if they have their wisdom teeth). The part of the tooth that can be seen above the gum is called the crown. All of our teeth help us to eat, but certain teeth have different jobs. Incisors are in the front of the mouth and we use them to bite and tear off small pieces of food. Molars are in the back of the mouth and help us to grind our food into little pieces so that it is easier to swallow.
The crown of each tooth is covered with a hard, shiny, protective material called enamel. Dentin is found beneath the enamel. Dentin makes up the majority of the tooth. Dentin is also hard, but not as hard as enamel. Within the dentin, is the pulp (the inner part of the tooth). The pulp of the tooth contains the nerve endings and the blood supply. When we feel pain in our tooth, this is where the sensation comes from. The root of the tooth reaches into the gums and is anchored in the jawbone.
These lessons are aligned with the Common Core State Standards ("CCSS"). The CCSS provide a consistent, clear understanding of the concepts and skills children are expected to learn and guide teachers to provide their students with opportunities to gain these important skills and foundational knowledge.
