Brushing Tips for Children Starting Their Dental Routine

Start Early, Even Before the First Tooth Appears

Good oral care begins long before your child can hold a toothbrush. From the moment that first little tooth pushes through – usually around six months, though every baby is different – it needs brushing twice a day. Getting in early does two things: it protects brand-new enamel from decay, and it teaches your child that brushing is simply part of the day, like bath time or putting on pyjamas.

Before teeth arrive, you can wipe the gums gently with a clean, damp muslin or a soft cloth wrapped around your finger. This gets your baby used to having their mouth touched, which makes the transition to a toothbrush far less of a shock. Once that first tooth appears, switch to a small, soft-bristled baby toothbrush.

At this stage, you will be doing all the brushing – your baby is simply getting used to the sensation, the taste of toothpaste and the routine.

Choose the Right Toothpaste and Brush for Their Age

Toothpaste for young children is not a case of one size fits all. The key difference is fluoride, which is what actually strengthens enamel and prevents decay, so getting the amount right matters.

• Under three years: use a toothpaste containing at least 1,000ppm fluoride, and smear only a thin film across the bristles. A smear is roughly the size of a grain of rice.
• Three to six years: use a pea-sized blob of toothpaste containing 1,350–1,500ppm fluoride. Check the tube, as children's toothpastes vary.
• Brushes: choose one with a small head and soft bristles designed for your child's age. A brush that is too big makes it hard to reach the back teeth comfortably.
• Replace brushes every two to three months, or sooner if the bristles look splayed and flattened.

Children's toothpaste comes in mild, fruity flavours for good reason – strong mint can sting and put little ones off. That said, if your child will happily use a family toothpaste with the right fluoride level, that is perfectly fine.

Gentle Technique That Actually Cleans

Young children cannot brush effectively on their own, so plan to do it for them, or at least finish the job, until they are around seven or eight. A useful position is to stand or sit behind your child with their head resting back against you, or have them lie down with their head in your lap – this gives you a clear view of every tooth.

Use small, circular movements, keeping the bristles angled towards the gum line, where plaque likes to gather. Work methodically around the mouth: outside surfaces, inside surfaces, then the chewing tops. Do not scrub hard – gentle and thorough beats vigorous every time. Two minutes is the target, and a timer or a favourite song helps everyone know when the job is done.

Encourage your child to spit, not rinse, after brushing. Rinsing with water washes away the fluoride that is still working to protect the teeth.

Making Brushing Genuinely Fun

Reluctance is normal, and a bit of theatre goes a long way. Try letting your child brush a teddy's teeth first, or give them a turn with the brush before you take over – it satisfies their urge to be in charge.

• Play a two-minute song and brush until it ends.
• Use a sticker chart, with a small reward at the end of a full week.
• Brush in front of a mirror so they can watch and copy you.
• Brush together as a family – children copy what they see far more than what they are told.
• Name the teeth as you go: "Now the little ones at the back!"

Keeping the same order every time – morning and last thing at night – builds the habit fastest. The bedtime brush is the most important, because saliva flow slows overnight and teeth are more vulnerable.

Handling the Common Battles

Some resistance is expected, particularly around eighteen months to three years, when a child's urge to do everything themselves is strong. If your child clamps their mouth shut, try brushing while they are relaxed, perhaps during a favourite programme, and keep sessions short and calm rather than turning them into a standoff.

If they chew the brush, let them – then have your turn. If they refuse toothpaste altogether, brush with water for a few days and reintroduce the paste gradually with a different flavour. Never force a brush into a resisting mouth, as this can make the whole routine frightening.

Building Habits That Last a Lifetime

Alongside brushing, keep sugary drinks and snacks to mealtimes rather than spreading them through the day. Water and milk are the kindest drinks for young teeth, and dried fruit, though healthy, is sticky and best saved for meals. If your child needs medicine, ask for a sugar-free version where possible.

Register with a dentist and take your child along for regular check-ups – NHS dental care is free for children under eighteen. Bringing them early, even just for a look, helps them grow up seeing the dental chair as ordinary rather than something to fear.

Consistency matters far more than perfection. A gentle, unhurried brush twice a day, with the right toothpaste and a bit of patience, will carry your child's smile well into adulthood.
