When to Start Brushing Your Baby’s Teeth: The Right Age and How to Do It 

You should start brushing your baby’s teeth as soon as the first tooth appears, usually around 6 months of age. Before the first tooth erupts, gently clean your baby’s gums with a soft, damp cloth after feeding. Once teeth begin to appear, use a soft-bristled baby toothbrush and a tiny smear of fluoride toothpaste to remove plaque and protect against early childhood cavities. Establishing good oral hygiene early helps promote healthy milk teeth, proper jaw development, and lifelong dental health.

At Dr. Gowds Dental Hospitals, our pediatric dentists guide parents on age-appropriate oral care, brushing techniques, and preventive dental care to ensure every child develops a healthy smile from infancy.

Why Is Early Oral Care Important?

Many parents believe brushing can wait until several teeth have appeared. However, bacteria can begin accumulating as soon as the first tooth erupts.

Starting oral hygiene early helps:

• Prevent early childhood caries
• Keep milk teeth healthy
• Reduce plaque buildup
• Protect developing enamel
• Encourage healthy brushing habits
• Support lifelong oral health

Good oral hygiene begins long before all the teeth appear.

When Should You Start Brushing Baby Teeth?

The answer is simple:

Begin brushing as soon as your baby’s first tooth erupts.

Most babies get their first tooth between 6 and 10 months, although every child develops differently.

Some babies develop teeth earlier, while others may not get their first tooth until after their first birthday.

Whenever the first tooth appears, brushing should become part of your baby’s daily routine.

Oral Care Timeline for Babies

Birth to 6 Months

Even before teeth erupt, oral hygiene matters.

After each feeding:

• Wipe the gums gently with a clean, damp gauze or soft cloth.
• Remove milk residue.
• Keep the mouth clean.

This also helps babies become comfortable with oral care.

Around 6 Months: First Tooth Appears

Once the first tooth erupts:

• Use a soft baby toothbrush.
• Brush twice daily.
• Use a smear (rice grain-sized amount) of fluoride toothpaste.
• Brush gently for about two minutes.

Parents should always perform the brushing at this stage.

1 to 3 Years

As more teeth erupt:

• Continue brushing twice daily.
• Use only a rice grain-sized amount of fluoride toothpaste.
• Brush all tooth surfaces and along the gumline.
• Avoid letting children brush unsupervised.

3 to 6 Years

Children may begin learning to brush independently, but parents should supervise.

Use:

• A pea-sized amount of fluoride toothpaste
• Gentle circular brushing motions
• Two minutes of brushing twice daily

How to Brush Your Baby’s Teeth Properly

Proper brushing is just as important as starting early.

Step 1: Choose the Right Toothbrush

Select a toothbrush that has:

• Soft bristles
• A small head
• A comfortable grip
• Age-appropriate design

Replace the toothbrush every three months or sooner if the bristles become worn.

Step 2: Use the Correct Amount of Toothpaste

Dental experts recommend:

• Rice grain-sized smear for children younger than three years
• Pea-sized amount after three years

Too much toothpaste increases the risk of swallowing excess fluoride.

Step 3: Brush Gently

Brush:

• Front surfaces
• Back surfaces
• Chewing surfaces
• Along the gumline

Use small circular motions rather than scrubbing aggressively.

Step 4: Brush Twice Daily

The two most important times are:

• After breakfast
• Before bedtime

Night-time brushing is especially important because saliva production decreases during sleep.

Should You Use Fluoride Toothpaste?

Yes. Most pediatric dentists recommend fluoride toothpaste because it helps strengthen enamel and prevent cavities.

Use only the recommended amount for your child’s age.

If you’re unsure which toothpaste is best, ask your pediatric dentist.

Common Brushing Mistakes Parents Make

Many parents unintentionally increase their child’s risk of cavities.

Common mistakes include:

Waiting Too Long to Start

Brushing should begin with the very first tooth.

Letting Children Brush Alone Too Early

Young children lack the hand coordination needed for effective brushing.

Parents should supervise until about 7–8 years of age.

Using Too Much Toothpaste

More toothpaste does not clean better.

Use only age-appropriate amounts.

Skipping Night Brushing

Milk and food particles left overnight allow cavity-causing bacteria to grow.

Putting Babies to Bed with Bottles

Sleeping with bottles containing milk, juice, or sweetened liquids greatly increases the risk of early childhood caries.

Final Thoughts

Knowing when to start brushing baby teeth is one of the most important steps parents can take to protect their child’s oral health. Brushing should begin as soon as the first tooth erupts, using a soft toothbrush and a small amount of fluoride toothpaste. Combined with healthy eating habits, regular dental check-ups, and good brushing techniques, early oral care can prevent cavities, support healthy jaw development, and establish lifelong habits that keep smiles healthy.
