February is Children’s Dental Health Month, and Delta Dental is sharing three dental-themed lesson plans that make it easy for educators to teach students healthy habits. Additional graphics and resources are available on the Delta Dental of Arizona blog

Marshmallow Teeth Model

Grade Level: K-2

MaterialsTeeth outline pattern, two large bags of jumbo marshmallows, scissors, glue, construction paper, yarn


  • Make a set of teeth out of large marshmallows as a class project. Use a magic marker to draw teeth outlines on construction paper.
  • Break students into three groups. Group one will flatten marshmallows for incisors, Group two will flatten and clip corners of marshmallows for canines. Group three will press in the middle of marshmallows to make molars.
  • Next, have each group glue marshmallows to the paper in the correct order: three molars on the side each end, one canine on each side and four incisors across the front.
  • Let dry and use the model to point out how food can get stuck in ridges and spaces. Practice “flossing” with some yarn.

Key Messages about Teeth

  • My front teeth are for biting.
  • My back teeth are for munching.
  • My pointed teeth are for tearing.
  • My back teeth are for crunching.
  • Teeth help you eat, smile and talk. Your smile makes you unique!

Happy Tooth/Sad Tooth

Overview: Students will identify nutritious foods and drinks that can keep our teeth healthy, and foods and drinks that can hurt our teeth.

Grade Level: K-1

MaterialsHappy/Sad Tooth Template, magazines, scissors, glue


  • Lead the class in reviewing the importance of teeth and explain that teeth help us chew healthy food, which keeps our bodies healthy, and helps us to learn. The choices we make in our foods and drinks can help or hurt our teeth.
  • Help students brainstorm a list of foods and drinks that they think would be healthy for our teeth and why.
  • Repeat with a list of foods and drinks that would be bad for our teeth and why.
  • Give each student a Happy Tooth sheet and a Sad Tooth sheet.
  • Instruct students to cut out healthy foods and drinks from magazines and glue them to the Happy Tooth.
  • Instruct students to cut out unhealthy foods and drinks from magazines and glue them to the Sad Tooth.
