Best Toothpaste for Kids by Age: A Pediatric Dentist’s Guide for Parents

By Dr. G (Dr. Gia S. Grannum), Board-Certified Pediatric Dentist

Agape Pediatric Dentistry | Peachtree Corners, GA

Standing in the toothpaste aisle can be surprisingly confusing when you’re shopping for your child.

Fluoride or fluoride-free? Strawberry or mint? Training toothpaste or regular toothpaste?

Does a toddler need something completely different from a 7-year-old? And what if your child refuses to brush because every toothpaste tastes “too spicy”?

Parents ask me these questions all the time.

At Agape Pediatric Dentistry, my goal is to make choices like these feel simpler. The best toothpaste for your child depends on their age, their individual cavity risk, and—very importantly—whether they will comfortably use it twice a day.

Here’s what parents should know.

The Quick Answer: What Toothpaste Should Kids Use?

For most children, a fluoride toothpaste used in the correct amount is recommended to help prevent cavities.

A simple age-by-age guide:

• First tooth through age 2: Use a tiny smear of fluoride toothpaste, about the size of a grain of rice.

• Ages 3–6: Use a pea-sized amount of fluoride toothpaste.

• Ages 6 and older: Continue using a fluoride toothpaste for cavity protection. Choose a flavor and texture your child will use consistently.

• Teens: A regular fluoride toothpaste is usually appropriate, although sensitivity, braces, enamel concerns, or other individual needs may affect the best choice.

The amount of toothpaste matters. Young children do not need a toothbrush covered from end to end with toothpaste.

Parents should also help or supervise brushing until their child has developed the coordination and consistency to clean all of their teeth well on their own.

When Should Babies Start Using Toothpaste?

Start brushing when your baby’s first tooth appears.

For children younger than 3, use only a very small smear of fluoride toothpaste—approximately the size of a grain of rice—and brush twice a day.

This small amount allows your child to receive the cavity-fighting benefit of fluoride while limiting how much toothpaste they may swallow.

Because babies and toddlers are still learning what brushing feels like, the goal at this stage is also to build a positive routine.

Keep it simple:

• Use a soft, age-appropriate toothbrush.

• Brush gently twice a day.

• Use only a rice-grain-sized smear of fluoride toothpaste.

• Let brushing become a normal part of the morning and bedtime routine.

• Keep toothpaste out of reach so your child does not use it unsupervised.

And remember: a baby does not need to know how to spit before you begin using the recommended small amount of fluoride toothpaste.

What About Fluoride-Free Toothpaste?

This is one of the most common questions I hear from parents.

Some families are understandably concerned about young children swallowing toothpaste and wonder whether fluoride-free toothpaste is a better place to start.

Fluoride-free toothpaste can help remove food and plaque during brushing, but it does not provide the same cavity-prevention benefit as fluoride toothpaste.

Current pediatric dental recommendations support using an age-appropriate amount of fluoride toothpaste beginning with the first tooth.

For a baby or toddler, that means using a very small amount—not switching to fluoride-free toothpaste simply because your child cannot spit yet.

If You Still Have Concerns About Fluoride

Please ask your child’s pediatric dentist.

Every child is different. Their cavity history, diet, enamel, brushing habits, exposure to fluoride from other sources, and overall health can all be considered when making personalized recommendations.

Parents should feel comfortable asking questions. Our goal is never to make you feel pressured—it is to help you understand the benefits, risks, and options so you can make informed decisions for your child.

Best Toothpaste for Toddlers and Preschoolers

For toddlers and preschoolers, the toothpaste you choose should protect their teeth and be something they are willing to tolerate.

Look for:

Fluoride for Cavity Protection

Choose a toothpaste labeled for cavity protection that contains fluoride unless your child’s dentist has recommended something different for their individual needs.

A Flavor Your Child Likes

Many young children dislike strong mint flavors. That is okay.

Strawberry, bubble gum, fruit, mild mint, and other child-friendly flavors may make brushing much easier.

The best toothpaste does not have to taste “grown-up” to work.

A Comfortable Texture

Some children are especially sensitive to foamy, gritty, or strongly flavored toothpaste.

If your child resists brushing because of the texture, consider trying a smoother gel or a lower-foam option.

Making brushing comfortable can be especially helpful for children with sensory sensitivities.

The Right Amount

For children younger than 3, use a rice-grain-sized smear.

From ages 3 through 6, use no more than a pea-sized amount.

More toothpaste does not mean cleaner teeth.

Best Toothpaste for Kids Ages 6–12

Once children reach elementary school, choosing a toothpaste becomes a little easier.

A standard fluoride toothpaste labeled for cavity protection is appropriate for many children.

At this age, I tell parents to focus on three things:

1. Does It Contain Fluoride?

Fluoride helps strengthen enamel and protect teeth from cavities.

If you are comparing several products, choosing one with the ADA Seal of Acceptance can also be a helpful shortcut. Toothpastes that receive the ADA Seal for cavity protection must contain fluoride and meet the ADA's requirements for safety and effectiveness.

2. Will Your Child Actually Use It?

If your child says mint toothpaste burns or tastes “too spicy,” there is no prize for forcing mint.

Choose another flavor.

Consistency matters much more than convincing your child that toothpaste is supposed to taste a certain way.

3. Can Your Child Brush Well Yet?

Even big kids sometimes rush.

They may brush the front teeth beautifully while missing the back molars, gumline, or inside surfaces.

Parents should continue checking in and helping as needed until their child can consistently brush all surfaces thoroughly.

A good goal is two minutes, twice a day.

“My Child Hates Toothpaste!” What Should I Do?

Sometimes the real problem is not brushing—it is the toothpaste.

If your child fights brushing every day, try to identify what is bothering them.

“It’s Too Spicy.”

Try a milder or non-mint flavor.

“It Feels Weird.”

Experiment with a smoother gel or less-foamy toothpaste.

“I Don’t Like the Smell.”

Let your child help select a different flavor.

“I Hate Brushing.”

Try separating the two issues.

First, find a toothpaste your child can tolerate. Then work on making the brushing routine predictable, calm, and positive.

Small choices can help children feel more involved. Letting them choose between two parent-approved toothpaste flavors or toothbrushes can make brushing feel less like a battle.

Does My Child Need “Natural” Toothpaste?

The word natural can mean many different things on a toothpaste package.

Rather than choosing based only on marketing words, turn the tube around and look at what the toothpaste actually does.

For most children, cavity protection should be the priority.

A toothpaste can have a simple ingredient list, use a mild flavor, avoid certain dyes, or fit your family's preferences while still containing fluoride.

If your child has experienced irritation or sensitivity with a particular toothpaste, bring the product—or a photo of the ingredient list—to their dental appointment. We can help you look for alternatives.

For Picky Kids or Those Who Dislike Mint

If your child finds traditional mint flavors too strong, below are a few kid-friendly options with mild, non-mint flavors:

• Tom's of Maine Silly Strawberry Anticavity Toothpaste

• Hello Kids Fluoride Toothpaste (Bubble Gum Flavor, Anticavity Formula)

• BURSTkids Marshmallow Sparkle Kids Toothpaste with Fluoride (Hint of Mint, Low-Spice Flavor)

Dye-Free and Natural Options: Cavity Protection Without Additives

These are many brands that focus on providing effective cavity protection without artificial dyes, sweeteners, or harsh chemicals to include:

• Burt's Bees Kids Fluoride Toothpaste (Dye-Free, Anticavity Formula)

• Made by Dentists Kids' Shark Fluoride Anticavity Toothpaste

• Tom's of Maine Children's Fluoride Toothpaste (Dye-Free, Anticavity)

What Toothpaste Should Teens Use?

Most teenagers can use a standard adult fluoride toothpaste.

At this stage, their needs may become more individualized.

Teens With Braces

Good plaque removal becomes especially important around brackets and wires.

A fluoride toothpaste should remain part of the daily routine, along with the cleaning tools recommended by your child's dental or orthodontic team.

Teens With Sensitive Teeth

Sensitivity should not automatically be ignored or covered up with a specialty toothpaste.

If your teen frequently complains that cold drinks, brushing, or certain foods make their teeth hurt, have the cause evaluated.

A sensitivity toothpaste may be helpful in some situations, but it is best to understand why the tooth is sensitive first.

Teens Interested in Whitening Toothpaste

Many teenagers begin paying more attention to the appearance of their smile.

Before adding whitening products—especially if your teen has sensitivity, enamel concerns, or orthodontic treatment—talk with their dentist about what is appropriate.

Whiter does not automatically mean healthier.

Healthy enamel comes first.

Does My Child Need Fluoride Mouthwash Too?

Not necessarily.

A good brushing routine with fluoride toothpaste is the foundation.

Fluoride mouth rinses are generally not recommended for children younger than 6 unless a dental or medical professional specifically advises their use, because younger children may swallow the rinse instead of reliably spitting it out.

For older children and teens, a pediatric dentist may recommend a fluoride rinse when there is a particular reason for additional cavity protection.

That could include individual cavity risk or certain orthodontic situations.

Think of mouthwash as an extra tool when needed—not a replacement for brushing and flossing.

When Toothpaste Choice Should Be Personalized

A toothpaste aisle cannot evaluate your child.

A pediatric dentist can.

It is especially helpful to ask about toothpaste if your child:

• Has had cavities before

• Is developing new cavities frequently

• Has white or weakened areas on the enamel

• Complains of tooth sensitivity

• Has braces or another oral appliance

• Has significant sensory sensitivities

• Refuses nearly every toothpaste you try

• Has dry mouth or other medical considerations

• Is very young and you are unsure how to begin brushing

• Has feeding, growth, breathing, or oral-development concerns you would like evaluated

Sometimes what looks like a simple toothpaste question becomes a useful opportunity to look at the child's oral health as a whole.

When Should My Child First See a Pediatric Dentist?

Parents often find this article because they are caring for their baby's very first teeth.

That is also the perfect time to establish a dental home.

Children should have their first dental visit when the first tooth appears or no later than the first birthday.

The first visit is not just about looking for cavities.

It gives parents a chance to ask questions about:

• Toothpaste and brushing

• Teething

• Feeding and diet

• Pacifier and thumb habits

• Tooth eruption

• Jaw and oral development

• Cavity prevention

• What to expect as more teeth arrive

Early visits also give children the opportunity to become familiar with the dental office before there is a problem.

At Agape Pediatric Dentistry, we work to make those early experiences gentle, positive, and comfortable so children can build confidence around dental care.

Why See a Pediatric Dentist?

Pediatric dentists receive additional specialty training focused specifically on the dental needs of infants, children, and teens.

As a Board-Certified Pediatric Dentist, I also understand that treating children is about much more than simply looking at teeth.

We consider your child's age, development, comfort, habits, growth, and individual needs.

At Agape, our goal is to help children understand that going to the dentist can be a positive experience while giving parents practical information they can actually use at home.

Dr. G's Final Toothpaste Advice

Parents often want me to name one toothpaste that is “the best.”

There really isn't one tube that is perfect for every child.

For most families, the best place to start is simple: Choose an age-appropriate fluoride toothpaste your child can comfortably use, use the correct amount, and brush twice every day.

For children under 3, remember: rice-grain-sized smear.

For children ages 3–6: pea-sized amount.

And if something does not seem right—your child keeps getting cavities, brushing is a daily struggle, their teeth are sensitive, or you simply aren't sure which product fits their needs—ask us.

Personalized advice is one of the reasons having a pediatric dental home matters.
