What you'll learn

  • Students will point to their teeth and name one job teeth do — chewing, talking, or smiling.
  • Students will look in a mirror and count teeth with a grown-up's help.
  • Students will repeat that even little baby teeth are important and need care.

Smile big! Do you see them? Those little white helpers are your teeth — and today you get to meet them.

Hello, teeth!

Look in a mirror and say hello. Your teeth are busy helpers:

  • They chew. Chomp, chomp! Teeth mash your food into tiny bites.
  • They talk. Say “ta-ta-ta” — feel your tongue tap your teeth? Teeth help your words come out clear.
  • They smile. Your smile says hello before you even talk!

Count with a grown-up

Little kids grow 20 baby teeth — ten up top, ten down below. That’s a lot of helpers! Ask a grown-up to help you count some in the mirror. Some may still be on their way — teeth show up little by little as you grow.

Baby teeth are small, but they are a big deal. They even save seats for the grown-up teeth that come when you’re bigger. So we take good care of every single one.

Say it with me: “Hello, teeth! I’ll take care of you!” Now try the little quiz below with your grown-up or teacher.

  • Printed pre/post knowledge checks from this packet (one per child, read aloud, used twice)

Procedure

  1. Pre-check (3 min): read each question aloud and let children point or answer together. Collect the sheets to compare after.
  2. Warm-up (2 min): everybody show your biggest smile! What do you see in a friend's smile? Teeth!
  3. Mirror time (4 min): with mirrors, children look at their own teeth. Help them count a few — kids grow 20 baby teeth in all.
  4. Tooth jobs (3 min): act them out together — chomp like you're eating an apple (chewing), say "ta-ta-ta" and feel your tongue tap your teeth (talking), give a giant grin (smiling).
  5. Wrap-up (1 min): teeth are little helpers — and helpers get taken care of! Tonight, teeth get brushed.
  6. Post-check (2 min): read the same questions aloud again and celebrate how much everyone knows now.

Tonight's healthy habit

Little kids grow 20 baby teeth, and each one matters — baby teeth help your child chew, talk clearly, and smile, and they save space for the grown-up teeth coming later. Caring for them starts now, even though they fall out one day.

Try it tonight

Play "smile mirror" tonight: sit together with a mirror, make silly grins, and count a few teeth out loud — then say goodnight to them with a good brushing.

El hábito saludable de hoy

Los niños pequeños tienen 20 dientes de leche, y cada uno importa — los dientes de leche ayudan a su hijo o hija a masticar, hablar claro y sonreír, y guardan el lugar para los dientes de adulto que vienen después. Hay que cuidarlos desde ahora, aunque un día se caigan.

Pruébalo esta noche

Jueguen al "espejo de sonrisas" esta noche: siéntense juntos con un espejo, hagan sonrisas chistosas y cuenten unos dientes en voz alta — después despídanse de ellos con una buena cepillada.
