How to Brush Your Child’s Teeth the Right Way
Most parents figure out toothbrushing on the go a quick Google search, a tip from a grandparent, or just winging it because your toddler is already melting down at bedtime. That’s completely normal. But getting the basics right early makes a real difference in whether your child grows up with healthy teeth or spends their school years in the dentist’s chair for fillings.
At Spanaway Children’s Dentistry, we walk parents through brushing guidance every single day. Here’s what we actually tell families in plain language, no dental jargon required.
Start Before the First Tooth Arrives
This one surprises a lot of new parents: you don’t have to wait for a tooth to start taking care of your baby’s mouth. Even before any teeth come in, bacteria can build up on the gums. After feeding, wipe your baby’s gums gently with a clean, damp washcloth or a soft silicone finger brush. It takes about 30 seconds and sets the foundation for good habits right from the start. Once that first tooth appears usually sometime between 4 and 12 months it’s time to introduce an actual toothbrush. Look for one with a small head and extra-soft bristles made for infants.
How Much Toothpaste Actually Goes on the Brush?
Toothpaste amount is one of the most commonly misunderstood things we see. Here’s the rule:
Under 3 years old: a smear of fluoride toothpaste about the size of a grain of rice
Ages 3 to 6: a pea-sized amount
Ages 6 and up: still a pea-sized amount (there’s no need to load the brush)
Yes, this applies to fluoride toothpaste, which the American Dental Association recommends for all children as soon as the first tooth erupts. At small amounts, fluoride toothpaste is safe and effective it’s one of the most proven tools we have for cavity prevention. If your child happens to swallow a tiny bit, a rice-grain-sized amount is nothing to worry about.
What Proper Brushing Actually Looks Like
A lot of kids do a quick swipe across the front teeth and call it done. That’s not quite enough. Here’s the technique to teach them:
Hold the brush at a slight angle toward the gum line about 45 degrees. Use small, gentle circular or back-and-forth strokes. Make sure to hit the outer surfaces, the inner surfaces, and the chewing surfaces of every tooth. Then do a light brush across the tongue to clear bacteria.
Two minutes, twice a day morning and before bed. That’s the standard, and it’s worth sticking to.
One thing many parents don’t realize: children shouldn’t be brushing fully on their own until around age 7 or 8. The fine motor skills needed to brush correctly especially the back molars don’t develop until around the same time a child can tie their own shoelaces. Until then, you brush first and let them “practice” after, or you guide their hand through it.
Make It Something They Want to Do
Getting a toddler or preschooler to stand still for two minutes while someone sticks a brush in their mouth is… a project. A few things that actually work:
Let them pick their toothbrush. A toothbrush with their favorite character on it, or one that lights up, suddenly becomes interesting. Same with toothpaste flavors bubblegum and strawberry are a lot more appealing to a four-year-old than “mint.”
Brush together. Kids are natural mimics. If they watch you brush, they want to do it too. Make it a side-by-side routine instead of something you do to them.
Use a timer or a song. Two minutes feels like forever to a small child. A simple toothbrushing song, a timer on your phone, or one of many apps designed specifically for this makes the time pass. Brush their favorite stuffed animal’s teeth first. Sounds silly, but it works. It shifts brushing from a thing that’s happening to them, to something they’re in on.
When Should Kids Start Flossing?
Flossing starts the moment any two teeth are touching which often happens around ages 2 to 3. You can use regular floss or the small floss picks made for children. Either works fine. The goal is to get into the tight spaces between teeth where the brush can’t reach, because that’s exactly where a lot of childhood cavities start. Kids typically can’t manage flossing on their own until around age 10. Until then, you’re the one doing it.
When to Bring Them In for Their First Dental Visit
The American Academy of Pediatric Dentistry recommends that every child see a pediatric dentist in Spanaway by their first birthday, or within six months of their first tooth coming in. Early visits aren’t about doing a lot of dental work they’re about making the dental office feel familiar and comfortable, and giving you a chance to ask questions about what’s normal for your child’s development.
Children who start dental visits early have significantly less anxiety at those appointments as they grow up. That relationship with a trusted dental team is genuinely worth starting early.

FREQUENTLY ASKED QUESTIONS
Q1: When should I start brushing my baby’s teeth?
Start cleaning your baby’s mouth even before the first tooth appears by wiping the gums with a damp, clean washcloth after feedings. Once the first tooth erupts typically between 4 and 12 months switch to a small, soft-bristled infant toothbrush and a rice-grain-sized smear of fluoride toothpaste. Starting early helps prevent bacteria buildup and gets your baby used to the sensation of having their mouth cleaned, making future brushing routines much easier to establish.
Q2: How much toothpaste should a toddler use?
For children under three, use a smear of fluoride toothpaste no bigger than a grain of rice. For children ages three to six, increase that to a pea-sized amount. This small quantity is enough to deliver the cavity-protection benefits of fluoride while keeping the amount swallowed to a safe minimum. Avoid loading the brush with a full stripe of toothpaste more isn’t better when it comes to toothpaste for young children. The American Dental Association supports fluoride toothpaste use starting with the very first tooth.
Q3: When can my child start brushing their own teeth?
Children generally develop the hand coordination needed to brush effectively on their own around age 7 to 8 roughly the same time they learn to tie their own shoes. Until then, parents should either brush for them or closely guide their technique, especially for the back molars, which are hardest to reach. A good approach is to let them brush first as “practice,” then go over the same teeth yourself to make sure nothing was missed.
Q4: Is fluoride toothpaste safe for young children?
Yes, fluoride toothpaste is safe for children starting from the first tooth, as long as you use age-appropriate amounts a rice-grain smear for under-threes, and a pea-sized dot from age three onward. Fluoride is one of the most well-researched tools in cavity prevention, and both the American Academy of Pediatric Dentistry and the American Dental Association recommend its use from infancy. If your child swallows a small amount at these dosages, there’s no cause for concern. You should, however, teach children not to swallow toothpaste intentionally.
Q5: How often should children come in for dental checkups?
Most children benefit from dental checkups every six months, starting from their first birthday or the eruption of their first tooth whichever comes first. Regular visits allow your child’s pediatric dentist to catch early signs of cavities, monitor jaw and bite development, apply preventive treatments like fluoride varnish and sealants, and keep your child comfortable and familiar with the dental environment. For children with higher cavity risk or specific developmental concerns, your dentist may recommend more frequent visits.
