Children's Dental Care: Toothpaste and Brushing by Age

Baby teeth aren't "practice teeth" you can afford to neglect. They hold the space adult teeth will grow into, help with speech and chewing, and — just as importantly — this is when brushing habits get built for life. The right toothpaste and technique change a lot by age.

Toothpaste by age

Ages 2–6: low-fluoride, pea-sized amount

Young children swallow a lot of toothpaste by accident, so formulas made for this age use a lower, safe fluoride level with flavors kids actually tolerate. In our children's toothpaste range, Elgydium Kids Banana and Kin Fluor Strawberry are both designed for this exact stage. Use a smear the size of a grain of rice for toddlers, a pea-sized amount from about age 3, and always supervise brushing so they spit rather than swallow.

Ages 6–12: junior formulas as adult teeth come in

As permanent teeth erupt, kids need more fluoride protection against the cavities that are most common in these years. Elmex Junior 6-12 ans is built for this transition period, with a full-strength fluoride level that's still gentle enough for a child's mouth.

Choosing the right toothbrush

A small head is non-negotiable — it's the only way to reach a child's back molars, where most cavities start. Making brushing fun genuinely helps compliance: a licensed-character brush like the Oral-B Kids Spiderman rechargeable or the President Kids Junior 5-11 can turn a daily battle into something your child actually looks forward to.

Building the habit

• Brush for them until they can tie their own shoelaces — most children lack the fine motor control for a thorough clean before age 6-7, even if they insist on doing it "myself."
• Twice a day, two minutes, morning and before bed — the evening brush matters most, since saliva flow drops overnight and bacteria have longer to work.
• First dental visit by age 1, or within 6 months of the first tooth appearing — not to treat anything, but so a dentist can check development early and your child gets used to the visit.
• Limit juice and sugary snacks between meals — frequency of sugar exposure matters more than quantity for cavity risk.

Frequently asked questions

When should I start brushing my baby's teeth?

As soon as the first tooth appears, with a soft infant brush or a clean damp cloth, even before any toothpaste is introduced.

Is fluoride toothpaste safe for young children?

Yes, at the age-appropriate dose. The risk with young children isn't the fluoride itself but swallowing excess amounts — which is why age-specific formulas and portion control (rice grain, then pea-sized) exist.

My child hates brushing — what can I do?

Let them pick their own brush and flavor, brush alongside them so they copy you, and keep sessions short and consistent rather than perfect. A rewards chart also works well for many families.
