Teaching Kids to Brush: Age-by-Age Guide

February 5, 2026 6 min read

From baby's first tooth to independent brushing, here's how to help your child develop great habits.

Teaching children proper brushing habits sets the foundation for a lifetime of healthy smiles. Here's what to do at each stage.

Babies (0-1 Year)

Before Teeth - Wipe gums with a clean, damp cloth after feedings - This removes bacteria and gets baby used to mouth cleaning

First Teeth - Use a soft baby toothbrush - Use a tiny smear of fluoride toothpaste (rice grain size) - Brush twice daily

Toddlers (1-3 Years)

Building Habits - Let them hold a toothbrush while you brush their teeth - Make it fun with songs or games - Continue using a rice-grain sized amount of toothpaste - Brush for them—they lack the dexterity

Preschoolers (3-6 Years)

Growing Independence - Increase to a pea-sized amount of toothpaste - Teach them to spit, not swallow - Let them try brushing, then you finish - Supervise closely

School Age (6-8 Years)

Developing Skills - Most children can brush independently - Still supervise and check their work - Teach proper technique: gentle circles, all surfaces - Introduce flossing with help

Tips for Success

  • Use a timer or brushing app
  • Let them choose their own toothbrush
  • Brush together as a family
  • Praise their efforts
  • Make it routine—same time every day

When to Step Back

Most children can brush effectively on their own by age 8, but this varies. Check their work occasionally to ensure good technique.
