When to Start Brushing Baby Teeth

You should begin brushing your baby’s teeth as soon as the first tooth appears. Even before this stage, gently cleaning the gums can help reduce bacteria and keep the mouth fresh.

Starting early helps protect against tooth decay and supports overall oral health. It also allows babies and toddlers to become familiar with brushing, making it easier to maintain the habit as they get older.

Choosing the Right Toothbrush

A soft-bristle toothbrush is best for babies. It is gentle on the gums and small enough to fit comfortably in your baby’s mouth.

Look for:

  • A small head designed for infants
  • Soft bristles to protect the gums
  • A comfortable handle for parents


Replacing the toothbrush regularly helps keep it effective.

How Much Toothpaste to Use

Using the correct amount of toothpaste is important for safety and effectiveness.

Guidelines include:

  • Use an amount the size of a grain of rice for infants
  • Increase to a pea-sized amount for older children


A small amount of t
oothpaste with fluoride helps protect teeth while keeping use safe.
