When Should You Start Brushing Baby Teeth?

You should start brushing your baby’s teeth as soon as the first tooth appears. This is an important step in protecting against tooth decay and maintaining a clean, healthy mouth.

Before teeth appear, gently cleaning your baby’s gums can help remove bacteria. Once the first tooth comes in, brushing should become part of your daily routine to help your baby get used to the habit.

How to Begin Cleaning Your Baby’s Mouth

Cleaning your baby’s mouth should begin even before teeth appear. This helps remove bacteria and keeps the mouth healthy.

Parents can:

  • Gently wipe gums with a clean cloth
  • Begin brushing your baby’s teeth when the first tooth appears
  • Make cleaning your baby’s mouth a daily habit


These steps support early oral health.

Choosing the Right Toothbrush

A soft-bristle toothbrush is best for babies. Soft bristles are gentle on the gums and effective at cleaning teeth.

Look for:

  • A small toothbrush head
  • Soft bristles for comfort
  • A handle that is easy to hold


Replacing the toothbrush regularly helps maintain good hygiene.

How Much Toothpaste Should You Use?

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

Guidelines include:

  • Use a smear of fluoride toothpaste for infants
  • Keep the amount of toothpaste about the size of a grain of rice
  • Increase to a pea-sized amount as your child grows


Using the right amount helps protect teeth while keeping them safe.

How Often Should You Brush Baby Teeth?

Brushing baby teeth should be done twice a day. This helps remove plaque and prevent tooth decay.

Parents should:

  • Brush your child’s teeth in the morning
  • Brush again before bedtime
  • Make brushing part of a daily routine


Consistency helps build strong habits.
