What you'll learn

  • Students will demonstrate brushing for two whole minutes, reaching the outer, inner, and chewing surfaces of the teeth.
  • Students will identify a pea-sized amount as the right amount of fluoride toothpaste for kids.
  • Students will explain why toothpaste is spit out and never swallowed.
  • Students will state that brushing happens twice a day — morning and night — with a grown-up's help.

Sugar bugs — grown-ups call them plaque — are a sticky film that covers your teeth. If they hang around too long, they can hurt your teeth and gums. The good news? Your toothbrush sweeps them away, and this lesson makes you a sweeping superstar.

The super smile routine

  1. Squeeze out a pea-sized dab of fluoride toothpaste. That little dab is all a kid needs — no more!
  2. Brush for two whole minutes. That’s one favorite song! Two minutes gives every tooth a turn.
  3. Give every side a turn. Brush the outside of your teeth, the inside, and the bumpy chewing tops. The sugar bugs hide everywhere!
  4. Spit it out! Toothpaste is for teeth, not for tummies. When you finish, spit — don’t swallow.
  5. Brush twice a day, every day. Once after breakfast, once before bed. Morning and night keep the sugar bugs away.
  6. Brush with a grown-up. Even super brushers do their best work with a helper watching — ask a grown-up to brush along until you’re a brushing pro.

Practice time

Put on a two-minute song and practice the whole routine in the air — outside, inside, chewing tops — until the music stops. Then take the after-lesson quiz below and watch your score grow!

Brushing Basics — Educator Lesson Plan

Grades K–2 (Ages 5–8) · Brushing & flossing · About 25 minutes

Learning objectives

  1. Students will demonstrate brushing for two whole minutes, reaching the outer, inner, and chewing surfaces of the teeth.
  2. Students will identify a pea-sized amount as the right amount of fluoride toothpaste for kids.
  3. Students will explain why toothpaste is spit out and never swallowed.
  4. Students will state that brushing happens twice a day — morning and night — with a grown-up's help.

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 toothbrush for each student, or one demonstration brush (soft bristles)
  • Fluoride toothpaste, for showing a pea-sized dab
  • A two-minute timer, or a favorite two-minute song
  • Printed pre/post knowledge checks from this packet (one per student, used twice)
  • Optional — a tooth model or big smile puppet, and a hand mirror

Procedure

  1. Pre-check (5 min): hand out the paper knowledge check, read each question aloud, and collect it. Keep the stack — you will compare it with the post-check.
  2. Warm-up (3 min): ask who brushed this morning. Introduce the sugar bugs — the sticky film grown-ups call plaque — and how brushing sweeps them away.
  3. Demonstrate (5 min): squeeze a pea-sized dab of fluoride toothpaste, then brush the model or air-brush for a full two minutes with the timer, narrating the outer, inner, and chewing surfaces. Finish with a big pretend spit — never swallow!
  4. Practice (5 min): everyone air-brushes together for two full minutes with the song, calling out each surface as a class.
  5. Wrap-up (2 min): ask when we brush (morning and night!) and who helps (a grown-up, until you are a brushing pro).
  6. Post-check (5 min): hand out the same knowledge check again. Compare class totals with the pre-check to see the learning — and celebrate it.

Tonight's healthy habit

Brush together — two whole minutes, morning and night, with a pea-sized dab of fluoride toothpaste. Kids brush best when a grown-up helps or watches, and when you finish: spit it out, never swallow.

Try it tonight

Tonight, play a favorite two-minute song and brush along until it ends. Let your child squeeze the pea-sized dab onto the brush — then check that shiny smile and celebrate together!

El hábito saludable de hoy

Cepíllense juntos — dos minutos completos, en la mañana y en la noche, con un poquito de pasta con flúor del tamaño de un chícharo. Los niños se cepillan mejor cuando una persona grande ayuda o los mira, y al terminar: la pasta se escupe, nunca se traga.

Pruébalo esta noche

Esta noche, pongan una canción favorita de dos minutos y cepíllense hasta que termine. Deje que su hijo o hija ponga el poquito de pasta (del tamaño de un chícharo) en el cepillo — ¡después revisen esa sonrisa brillante y celebren juntos!
