What you'll learn

  • Students will state that teeth get brushed two times every day — morning and night.
  • Students will show that a grown-up brushes with them and helps every time.
  • Students will repeat the toothpaste rules — just a little dab, and spit, don't swallow.

Brushing your teeth is a team sport — and your grown-up is the team captain!

The brushing team

Little kids’ hands are still learning tricky jobs, so a grown-up brushes with you every time. Maybe they hold the brush with you, maybe they finish the spots you missed. That’s not baby stuff — that’s how smile champions train!

The three team rules

  1. Brush two times every day. Once in the morning after breakfast, once before bed. Morning brush, night brush — every day!
  2. Just a little dab of fluoride toothpaste. For big preschool kids it’s the size of a pea. Teeny-tiny — that’s all your teeth need!
  3. Spit it out — don’t swallow it down! Toothpaste does its job on your teeth, then it’s done. Give a big spit at the end, like a whale saying goodbye.

While you brush, the toothbrush visits every tooth: the fronts, the backs, and the bumpy chewy tops. A favorite song makes the visit fun — brush until the song is done!

Now grab your grown-up and show off what you know in the little quiz below. Go, team smile!

Brushing with a Grown-Up — Educator Lesson Plan

Pre-K (Ages 3–5) · Brushing & flossing · About 15 minutes

Learning objectives

  1. Students will state that teeth get brushed two times every day — morning and night.
  2. Students will show that a grown-up brushes with them and helps every time.
  3. Students will repeat the toothpaste rules — just a little dab, and spit, don't swallow.

Standards alignment (NHES)

  • NHES 1.2.1 — Identify that healthy behaviors impact personal health. (Standard 1, Pre-K–Grade 2, NHES 2nd ed., 2007)
  • NHES 7.2.1 — Demonstrate healthy practices and behaviors to maintain or improve personal health. (Standard 7, Pre-K–Grade 2, NHES 2nd ed., 2007)

Materials

  • A demonstration toothbrush (soft bristles) and a tube of fluoride toothpaste
  • A big smile puppet, tooth model, or stuffed animal to practice on
  • A favorite short song for brush-along time
  • 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): who brushed their teeth this morning? Hands up! When else do we brush? Before bed!
  3. Watch me (4 min): show a tiny pea-sized dab on the brush. Brush the puppet's teeth gently — front, back, and the chewy tops — while the class air-brushes along.
  4. Team talk (3 min): who holds the brush at home? A grown-up helps every time — because grown-ups are brushing coaches, and little hands are still learning.
  5. Rules rap (1 min): say it together — "Little dab! Brush all around! Spit it out — don't swallow it down!"
  6. Post-check (2 min): read the same questions aloud again and celebrate how much everyone knows now.

Brushing with a Grown-Up

Family take-home · Para llevar a casa

Tonight's healthy habit

Brush your child's teeth twice a day — after breakfast and before bed — with fluoride toothpaste: a pea-sized dab at ages 3–6, just a rice-grain smear under 3. Little kids can't brush well alone yet, so a grown-up brushes with them, and everyone spits instead of swallowing.

Try it tonight

Make tonight a brushing concert: pick a favorite song, and brush together until it ends — grown-up hand over little hand. Finish with the big spit and a "ta-da!"

El hábito saludable de hoy

Cepille los dientes de su hijo o hija dos veces al día — después del desayuno y antes de dormir — con pasta con flúor: un poquito del tamaño de un chícharo de los 3 a los 6 años, y apenas como un granito de arroz antes de los 3. Los niños chiquitos todavía no pueden cepillarse bien solos, así que una persona grande cepilla con ellos, y todos escupen la pasta en vez de tragarla.

Pruébalo esta noche

Hagan esta noche un concierto de cepillado: escojan una canción favorita y cepíllense juntos hasta que termine — la mano grande sobre la manita. Terminen con el gran escupitajo y un "¡ta-rán!"
