Every parent knows brushing is important. But most of us weren't told exactly when to start — or how involved we should still be at ages 5, 6, or 7. The truth is, oral care begins earlier than most people think, and the habits you build now will follow your child for life.
When to start brushing
Brushing should begin as soon as the first tooth appears — typically around 6 months of age. Yes, that early. The moment a tooth breaks through, it's vulnerable to decay, and gentle cleaning twice a day is the first line of defense.
Start brushing now
Use a soft-bristled infant brush and a tiny smear of fluoride toothpaste — about the size of a grain of rice.
Increase toothpaste
Bump up to a pea-sized amount. Kids this age start learning to spit — but supervision is still essential.
At the very first tooth, you need three things:
- A soft-bristled infant or toddler brush
- A tiny smear of fluoride toothpaste (grain-of-rice size)
- Two brushing sessions per day — morning and night
When to start flossing
Flossing should begin when two teeth start touching — which usually happens between ages 2 and 3. At that point, food and plaque get trapped between teeth in places a toothbrush simply cannot reach.
Begin flossing now
Use soft floss picks designed for kids. Make it part of the nightly routine from the start.
Build toward self-flossing
With practice and guidance, kids begin managing more of their routine on their own — but still benefit from check-ins.
The average American family spends over $500 per child, per year on dental care. Cavities are the #1 chronic disease in children — and most are preventable with consistent early habits.
Why parent involvement matters more than you think
Here's the part most parents don't realize: kids don't have the fine motor coordination to brush effectively on their own until around age 6 to 8. Before that, they're missing spots — and building the habit of rushing through it.
That means for the first several years of your child's life, you're not just reminding them to brush. You're guiding them, showing them where to reach, and teaching technique that will stick for decades.
What parent involvement looks like at each stage
Ages 0–2: You do everything. Brush gently for them, twice a day. Make it calm and consistent.
Ages 3–5: Let them "try first," then you go after. They practice the motion — you make sure it's actually clean.
Ages 6–8: Supervision over full control. Watch, guide, and celebrate when they do it right. Habits are being cemented now.
Ages 9–10: Check-ins and accountability. The goal is an independent routine — but consistency still needs reinforcement.
Why starting early is so important
Children don't automatically develop good oral hygiene. They learn it. Without early guidance, most kids fall into patterns of incomplete brushing — rushing through it, skipping spots, avoiding flossing entirely. These habits can lead to cavities, gum problems, and years of uncomfortable dental visits.
The earlier you start, the more natural it becomes. A child who grows up brushing twice a day doesn't fight it — it's just part of life. That's the goal.
Gary makes every step easier
The Smilen's animated character Gary lives on the touchscreen and walks kids through every part of their routine — front teeth, back teeth, tongue, and flossing — with animations they can actually follow. No more guessing if they're doing it right. No more reminding. Gary handles it, every morning and every night.
The bottom line
Start brushing when the first tooth arrives. Start flossing when teeth begin to touch. Stay involved until at least age 8. And find ways to make the routine something your child actually looks forward to — because the habits that stick are the ones that feel good.
The brushing battle doesn't have to be your nightly reality. The right tools and the right routine make all the difference.
Turn brushing from a battle into a win — every night.
