Choosing a baby toothbrush comes down to three things: a small head, soft bristles and a handle the adult can hold comfortably. You use it from the first tooth, at around six months, with a smear of fluoride toothpaste. Everything else, from silicone finger brushes to electric brushes and fun shapes, is about comfort, not official advice.
This guide covers the types of brush, the criteria that matter, when to replace it and what to do when your baby refuses. It draws on the advice sheet from the Union française pour la santé bucco-dentaire (UFSBD, the French oral health association) and on guidance from the UK's NHS. For toothpaste, the age to start and fluoride, our article on brushing your baby's teeth according to official guidance remains the reference.
Which baby toothbrush should you choose from the first tooth?
The short answer: a baby toothbrush with a small head and soft bristles, suited to the age shown on the packaging, held by the adult. The UFSBD asks that every child has their own brush, suited to their age and the size of their mouth. The NHS says the same thing: a small, soft brush that matches the child's age, as soon as the first milk tooth comes through.
Neither organisation insists on a brand, a handle shape or a material. They set the framework, not the model. That's good news: an entry-level brush that meets these three criteria does the job.
Before the first tooth: do you need a brush yet?
No. Before any teeth appear, there's nothing to brush. The UFSBD sheet starts brushing ‘from the first teeth’, at around six months, and the NHS points out that this first tooth can arrive earlier or later. Wiping the gums with a damp gauze pad is sometimes suggested to get your baby used to the routine. None of the sources we read makes this a recommendation, and there's no need to buy anything for it.
That time before the first tooth is useful for one thing, though: letting your baby discover the brush as an object. They put it in their mouth, chew on it, examine it. It's the same exploratory behaviour described in our article on babies who put everything in their mouth, and it paves the way for accepting brushing.
Silicone finger brush or handled brush: which one to start with?
The silicone finger brush
The finger brush slips over the adult's index finger. Its surface has small, soft nubs that rub the first teeth and the gums. It gives good control over pressure and position, because the parent can feel what they're doing. It's best suited to the first two to four teeth, while the mouth is still very small.
Its limits are real. The nubs clean the sides of the teeth less well than a bristle brush, and neither the UFSBD nor the NHS mentions the finger brush: both talk about a toothbrush. Think of it as a transition tool, not as the brush for the first two years. A child who already has molars needs bristles that reach into the grooves.
The handled brush
This is the reference tool for both organisations. As soon as your baby has several teeth, and at the latest when the first molars arrive at around twelve to eighteen months, the handled brush takes over. The handle lets the adult reach the back of the mouth without putting a finger between the jaws, which matters with a child who bites.
Many parents keep both: the finger brush for the very first months, then the brush. Others go straight to the brush. Both choices are reasonable, as long as the adult brushes twice a day.
The criteria that really matter
Head size
The head should fit easily into the mouth and turn to reach the inner surfaces of the teeth. Packaging shows an age range, usually ‘0-2 years’ or ‘0-3 years’, which corresponds to a head of about one and a half to two centimetres. A head that's too big forces you to brush from the front, so badly, and triggers the gag reflex. If you're torn between two sizes, go for the smaller one.
The bristles
Soft, always. A baby's gums bleed easily, and firm bristles hurt without cleaning any better. The bristles should be numerous, with rounded tips, and the tuft should not stick out beyond the head. Avoid brushes whose bristles splay after two weeks: it's a sign of poor quality, and a misshapen brush cleans badly.
The handle
Until the age of two or three, the adult does the brushing, and the UFSBD is clear on this. So the handle needs to suit an adult's hand: long enough to hold firmly, not too thin. A very short handle designed for a child's hand gets in the parent's way. At around two, a second brush with a short, chunky handle lets your child ‘brush’ on their own, before the adult takes over again.
Material and finish
The handle is usually plastic, sometimes bamboo or silicone. The official sources don't recommend one material over another. What matters is the absence of sharp edges, small detachable parts and flaking paint, since the brush will end up being chewed. A toothbrush is not a toy in the regulatory sense: it isn't subject to EN 71 testing. So choose it with the same reflexes as for anything that goes in the mouth.
Electric toothbrush for babies: from what age?
No official French guidance provides for an electric brush before the age of three. The UFSBD sheet and the NHS page don't mention it for this age group. Manufacturers themselves usually state ‘from 3 years’ on their children's models. Before that age, a soft manual brush is enough, and in any case it's the adult who holds the brush.
An electric brush doesn't replace the parent's technique. It vibrates, but it doesn't position itself on every surface of every tooth. For a two-year-old with twenty milk teeth, the limiting factor isn't the power of the brush, it's how long the adult manages to keep brushing. If you fancy an electric one later, wait until your child tolerates the noise and vibration, often after the age of three.
When should you replace your baby's toothbrush?
The UFSBD recommends replacing the brush when the bristles are worn, roughly every three months. With a baby who chews, wear often comes sooner: squashed or splayed bristles are reason enough, whatever the timing. Our article on brushing adds a second case: after an infection, the brush gets changed.
A practical tip: write the date on the handle with a marker, or change the brush every time the season changes. Keep two or three in reserve, especially if you go for a particular model your child accepts well.
Your baby chews the brush instead of letting you brush: what can you do?
This is the most common situation between six and eighteen months. Chewing the brush soothes the gums during teething and is part of exploring. The useful trick is to use two brushes: one your baby holds and chews, one the adult uses for brushing. Your child feels they're doing it themselves, and the real brushing gets done.
Position matters too. With your baby sitting on your lap, back against you, head tilted slightly back, you can see all the teeth and there's less of a struggle. An older child can stand at the basin, level with the mirror, using a step stool: our potty, toilet seat and step stool is designed for exactly that once the potty stage is over. Seeing a parent brush their teeth at the same time works better than any explanation: imitation in babies is the main driver of this learning.
If the refusal goes on, lower the stakes rather than the frequency: two very short brushing sessions are better than one long, fraught one. Brushing is part of the independence that builds between two and three, just like learning to wash their hands or getting dressed on their own.
Cleaning, storage and hygiene
After each brushing session, rinse the toothbrush under clean water and leave it to dry head up, in the open air. The UFSBD advises against storing it in a closed, damp case, where bacteria multiply. No sterilising and no dishwasher: heat warps the bristles. Each child has their own brush, never shared, not even between brothers and sisters.
One last, often overlooked detail: the UFSBD asks you to put the toothpaste on a dry brush. Wetting the brush first dilutes the fluoride before it even reaches the tooth.
What doesn't depend on the brush
The brush is the tool, not the method. Three things matter more than the model you choose. First, toothpaste: fluoride at 1,000 ppm, a smear across the width of the brush from six months to three years according to the UFSBD, the equivalent of a grain of rice according to the American Academy of Pediatrics. Then frequency: twice a day, including in the evening after the last meal. And finally the first appointment: the American Academy of Pediatrics places it before the first birthday or within six months of the first tooth. In France, the M'T dents check-up, covered by health insurance, starts at three.
Key takeaways
- A baby toothbrush with a small head, soft bristles and a handle that's comfortable for the adult: that's the whole specification.
- The silicone finger brush works for the very first teeth; the handled brush takes over once the molars arrive.
- No electric brush recommended before three, and never as a substitute for the parent's brushing.
- Replace the brush roughly every three months, as soon as the bristles splay, and after an infection.
- Two brushes, a good position and the parents' example sort out most refusals.
