Simple but Effective Tips to Keep Children’s Teeth Healthy
Lately, we’ve been seeing something worrying at our practice: a noticeable rise in tooth decay in children, where some are as young as two years old. For many families, this comes as a surprise, especially when they feel they are doing all the right things.
The truth is, much of it comes down to hidden sugars in everyday foods, even those that are marketed as healthy for kids.
As the saying goes, prevention is better than cure, and when it comes to children’s oral health, that could not be more true. The good news is that early childhood dental care doesn’t need to be complicated. A few simple, consistent habits at home can make a significant difference to how your child’s teeth develop and hold up over time.
Here are four practical tips for kids’ dental care that we recommend to families at our practice.
1. Limit Snacking and Create Food-Free Windows
One of the most important things you can do to prevent tooth decay in children is to reduce how often their teeth are exposed to sugars and acids throughout the day.
Every time a child eats, even something seemingly harmless, bacteria in the mouth produce acid that can attack tooth enamel. Frequent snacking or “grazing” means this acid attack is almost constant, which significantly increases the risk of toddler tooth decay and decay in older children alike.
We recommend aiming for no more than four to five mealtimes per day, with each eating session lasting no longer than 40 minutes. Between those times, plain water is the only thing that should be consumed.
If your child feels hungry between meals, that’s okay. They will generally eat more at the next mealtime. This rhythm supports not just dental health for toddlers and children, but also helps them better regulate their appetite over time.
2. Choose Whole Fruits Over Juices or Dried Fruit
This is one of the most common areas where hidden sugar and tooth decay are linked, and it often surprises parents.
Juicing or drying fruit concentrates its natural sugars and makes it easy to overconsume. One glass of fresh orange juice, for example, may contain the sugar equivalent of seven to eight whole oranges, which is far more than any child would eat in one sitting.
Dried fruits like sultanas are over 60% sugar and, because they are sticky, they cling to the teeth surfaces for longer. In many cases, they can be more damaging to children’s teeth care than a piece of chocolate, which melts away relatively quickly.
Whenever possible, stick to fruit in its whole, natural form. Your child gets the fibre, the nutrients, and far less sugar exposure per serve.
3. Brush at Night Using the Right Toothpaste
When it comes to brushing children’s teeth, two things matter most: doing it properly at night, and using the right toothpaste.
For fluoride toothpaste for kids, we recommend using a tiny amount (about half a grain of rice) of adult-strength toothpaste labelled for ages 6 and above. This is because toothpaste marketed for younger children in Australia is often below 1000 ppm fluoride, the level needed to meaningfully strengthen enamel. Many European countries don’t even sell toothpaste below that concentration, yet here it’s common in products aimed at toddlers.
After brushing, ask your child to spit if they can. However very young children who aren’t able to spit don’t need to. By using just a tiny amount of toothpaste (less than half a rice grain amount), it is not a problem that they swallow it. Toothpaste is not a soap that aids in the cleaning of the teeth. The goal of toothpaste is to act as a topical cream that strengthens enamel over time. Rinsing it away reduces its effectiveness. It is much better to use a tiny amount of an adequate strength toothpaste, rather than a large sausage of weak toothpaste.
4. Brush With Their Head in Your Lap
Young children simply don’t have the hand coordination or dexterity to brush their own teeth effectively. That’s why we recommend that parents brush their child’s teeth once a day at night until they are around seven to ten years old.
The morning brush is a great opportunity to let children practise on their own and build good oral hygiene habits. But at night, when teeth are most vulnerable during sleep, a thorough parent-led brush is essential.
The most effective technique is to have your child lie down with their head in your lap, just as it would be at the dentist. This position gives you a clear view of the mouth and makes it much easier to reach all surfaces, including those tricky back molars. Lift their lip so you can see what you’re doing, and be methodical rather than rushing through. Being thorough matters more than brushing for a set time.
It’s worth remembering that the back baby teeth don’t fall out until around age 12. They play an important role in jaw development, speech, and chewing, which is exactly why baby teeth care and early action matter so much.
When Should a Child See a Dentist?
We encourage families to consider booking their child’s first dental visit from around age two. Early visits are not just about checking for problems — they help children become familiar and comfortable with the dental environment, which makes future visits far easier for everyone. Building that familiarity early is one of the most valuable things you can do for a child’s long-term relationship with dental care.
For families eligible under the Medicare Child Dental Benefits Scheme, bulk-billed visits may be available. When you’re eligible, this means the cost of seeing a child dentist early does not have to be a barrier.
Small Habits, Lasting Smiles
Children’s teeth care does not need to be overwhelming. Reducing snacking windows, choosing whole fruit, brushing well at night with the right toothpaste, and starting dental visits early help lay a strong foundation for healthy teeth for kids well into adulthood.
And, of course, while a proper dental routine at home is important, it is also important to have your children’s teeth monitored by a qualified dentist.

Frequently Asked Questions
- When should my child first see a dentist?
We recommend bringing children in from around age two. Early visits help identify any concerns early and, just as importantly, help children feel comfortable in the dental environment before any treatment is ever needed.
- Is tooth decay in children really that common?
Unfortunately, yes. Tooth decay is one of the most common chronic conditions in Australian children. Much of it is preventable with good home habits and regular dental check-ups from an early age.
- Can baby teeth get cavities?
Yes, and it matters more than many people realise. Baby teeth (especially the back molars) stay in the mouth until around age 12. Decay in baby teeth can cause pain, affect speech and chewing, and may impact how adult teeth develop.
- What toothpaste should I use for my child?
We recommend a toothpaste with at least 1000 ppm fluoride, which in Australia is typically found in products labelled for ages 6 and above. Use only a tiny amount, about half a grain of rice, and ask your child to spit but not rinse afterwards.
- Is fruit juice bad for children’s teeth?
Unfortunately, fruit juice, even those labelled “natural” or “no added sugar” varieties, concentrates the sugars found in fruit and exposes teeth to acid repeatedly. Whole fruit is a much better option. Water should be the main drink between meals for children of all ages.
- How do I brush my young child’s teeth properly?
Have your child lie down with their head in your lap so you have a clear view of their mouth. Lift their lip, use a small amount of fluoride toothpaste, and brush all tooth surfaces methodically, including the back molars. Aim to do this once a day at night until your child is around seven to ten years old.
