When Should You Start Caring for Baby Teeth? A Pediatric Dentist’s Guide for Parents

By Dr. Lisneida “Dr. Lis” Arjona, Once Upon a Tooth Pediatric Dentistry, Eastchester, NY

If you’ve ever wondered, “Do baby teeth really matter if they fall out anyway?”—you’re not alone.

As a pediatric dentist (and a parent!), I hear this question all the time. The truth is: baby teeth play a critical role in your child’s development, and caring for them early sets the foundation for a lifetime of healthy smiles.

In this guide, we’ll walk you through:

• When to start dental care

• Why baby teeth are so important

• Easy, age-by-age care tips

• Common myths (and what actually matters)

Why Baby Teeth Matter More Than You Think

Baby teeth may be temporary, but their impact is long-lasting.

1. They Help Your Child Speak Clearly

Teeth help guide the tongue and lips when forming sounds. Without proper tooth development, children may struggle with pronunciation or develop speech issues like lisps.

2. They Support Healthy Eating and Nutrition

Strong baby teeth allow children to chew properly, which is essential for digestion and getting the nutrients they need to grow.

3. They Guide Adult Teeth Into Place

Baby teeth act as natural placeholders. Losing them too early can lead to:

• Crowding

• Misalignment

• Future orthodontic issues

When to Start Dental Care for Your Baby

Start Before the First Tooth Appears

Even before teeth come in, gently wipe your baby’s gums with a soft, damp cloth after feedings.

First Tooth = Time to Brush

As soon as that first tiny tooth appears:

• Use a soft-bristled infant toothbrush

• Apply a smear of fluoride toothpaste (grain of rice size)

Schedule the First Dental Visit by Age 1

The American Academy of Pediatric Dentistry recommends: First visit by age 1 OR within 6 months of the first tooth.

Early visits help:

• Prevent cavities

• Build comfort with the dentist

• Catch small issues before they become big ones

At Once Upon a Tooth, we call this creating a “dental home”—a place where your child feels safe, supported, and even excited to visit.

Easy Daily Care Tips for Baby Teeth

Brush Twice a Day

• Ages 0–3: smear of fluoride toothpaste

• Ages 3–6: pea-sized amount

• Use gentle, circular motions

Avoid Baby Bottle Tooth Decay

One of the most common issues we see.

Try to avoid:

• Bottles with milk or juice at bedtime

• Frequent sipping on sugary drinks

Tip: If your child needs a bedtime bottle, use water.

Encourage Healthy Habits Early

• Transition to a cup by age 1

• Limit sugary snacks and drinks

• Make brushing fun (songs, timers, routines!)

Common Myths About Baby Teeth (And the Truth)

Myth: “They fall out anyway, so cavities don’t matter.”

Truth: Untreated cavities can cause pain, infection, and damage to developing adult teeth.

Myth: “Teething causes fever and illness.”

Truth: Teething may cause mild discomfort, but high fever or diarrhea is not normal—check with your pediatrician.

Myth: “Thumb-sucking is always bad.”

Truth: It’s normal in early years. However, if it continues past age 4–5, it may affect:

• Tooth alignment

• Jaw development

Myth: “Losing baby teeth early isn’t a big deal.”

Truth: Early tooth loss can lead to spacing problems and may require intervention like space maintainers.

When to See a Pediatric Dentist

You should schedule a visit if your child:

• Has their first tooth

• Is nearing their first birthday

• Shows signs of discomfort or tooth discoloration

• Experiences a dental injury

Regular checkups every 6 months help keep everything on track.
