Parents often ask us how many sweets are allowed. For teeth, though, how often matters more than how much. A child who grazes on biscuits and sips juice all day is at greater risk than a child who has one sweet after a meal.
Tooth decay is very common in children, and to a large extent it can be prevented. In this guide we explain how decay develops, which habits feed it and which simple changes at home make a difference, without bans and without guilt.
How tooth decay happens
Bacteria live on the teeth and feed on the sugars and starches in food. Every time a child eats or drinks something sugary, the bacteria produce acids that soften the enamel for a while. Saliva then helps the tooth recover.
If these sugar attacks happen again and again, the tooth never gets the chance to recover, and over time a cavity forms. That is why a sweet eaten with a meal is better for teeth than the same sweet spread out in small bites over the whole afternoon.
The bottle at night
One of the most common causes of decay in very young children is going to bed with a bottle of milk, juice or another sweet drink. During sleep there is less saliva, and whatever stays in the mouth sits on the teeth for hours. The upper front teeth are usually affected first.
- After the evening brush, the only drink that does not harm teeth is water.
- Do not let your child fall asleep with a bottle in their mouth.
- From around the first birthday, gradually encourage a cup instead of a bottle, as your paediatrician advises.
Every family has its own needs when it comes to night feeds and breastfeeding. If you have questions, talk them through with us and your paediatrician. What matters is that the teeth are cleaned well before bed.
Juice, fizzy drinks and "healthy" drinks
Fruit juice, even with no added sugar, contains the fruit's own sugars and acids. For teeth, whole fruit is a better choice than its juice. If your child drinks juice, keep it to a small amount with a meal, not in a bottle carried around all day.
- Fizzy drinks: contain sugar and acids that wear away enamel. Sugar-free versions are acidic too.
- Sports and energy drinks: not for everyday use by children; for most, water is enough after exercise.
- Flavoured milks, chocolate drinks and iced teas: often contain a fair amount of sugar.
- Water and plain milk: the most tooth-friendly drinks between meals.
Snacks: what is hiding in the packet
Sugar is not only found in sweets. Cereal bars, flavoured yogurts, biscuits marketed for children, breakfast cereals and ketchup often contain more than we think, even when the packet says "no added sugar", as they may contain syrups or concentrated fruit juice.
Sticky foods such as jelly sweets and dried fruit cling to the grooves of the teeth and stay there longer. Starchy savoury snacks such as crisps and crackers also feed the bacteria when eaten often.
For snacks between meals, choose:
- Fresh fruit and vegetables, cut in a way that suits your child's age.
- Cheese or plain yogurt.
- A boiled egg.
- Nuts for older children; for young children they are a choking risk.
Simple rules for home
- Regular mealtimes: main meals and a few planned snacks, rather than grazing all day.
- Sweet things with meals, not between them.
- Water between meals and in the school bottle.
- After the evening brush, nothing but water.
- Medicines in syrup: if your child takes a medicine for a long time, ask the doctor or pharmacist whether a sugar-free version is available.
- Let grandparents know too, or anyone who looks after your child, so the same rules apply everywhere.
Sweets do not need to be banned. A slice of cake at a party or a dessert after Sunday lunch is not a problem if the teeth are brushed well that evening. Bans often make sweets more attractive; a steady routine works better.
Brushing and regular check-ups
Diet goes hand in hand with brushing: twice a day, with a fluoride toothpaste in an amount suited to your child's age, and with your help or supervision until about 7–8 years old. You can read more about toothpaste amounts in our guide to baby teeth.
At regular check-ups, about every six months, we look for early signs of decay such as dull white patches. Early decay that is caught in time can sometimes be stopped with better brushing and less sugar, without a filling. Where appropriate, we may also suggest a fluoride varnish for extra protection. If your child has not had a first visit yet, see also our guide "Children's Dentistry in Aglantzia: Your Child's First Dental Visit".

Frequently asked questions
Is fruit juice better than a fizzy drink?
It has vitamins, but for teeth it also contains sugars and acids. It is best given in small amounts with a meal. Whole fruit is preferable to its juice.
Should my child brush after every sweet?
There is no need. Good brushing twice a day is enough. After something sweet, a drink of water helps clear the mouth. After juice or a fizzy drink, it is better to wait a while before brushing, because the enamel is briefly more vulnerable.
Does sugar-free chewing gum help?
For older children, sugar-free gum after a meal increases saliva, which helps the teeth. It does not replace brushing, though, and it is not suitable for young children because of the risk of choking.
My child has decay even though they do not eat many sweets. Why?
Decay has many causes: how often your child eats, hidden sugar in snacks and drinks, how well the teeth are cleaned, saliva and even the shape of the teeth. At a check-up we can look together at what applies to your child.
Are supermarket snacks made for children good for teeth?
Not always. Many contain sugar, syrup or concentrated fruit juice, even when they say "no added sugar". Read the ingredients and, whatever the packet says, offer them with a meal where possible.
