Tooth decay remains one of the most common chronic health conditions affecting Australian children. National data has shown that a substantial proportion of children have experienced decay in their baby teeth by the time they start school. That statistic surprises many parents, because baby teeth are often seen as temporary and less important. In reality, they play a vital role in eating, speech, confidence and guiding adult teeth into position.
The encouraging news is that most childhood decay is preventable. Here is how parents can support healthy teeth at every stage.
Babies and the First Tooth
Oral care begins before the first tooth appears. Gently wiping a baby’s gums with a soft, damp cloth after feeds gets them used to the sensation. Once teeth begin to arrive, usually around six months, start cleaning them twice a day with a soft infant toothbrush and water.
Avoid putting babies to bed with a bottle of milk or juice. Prolonged exposure to sugars while sleeping is a common cause of early childhood decay, sometimes called bottle caries.
Toddlers and Preschoolers
From around eighteen months, a small smear of low-fluoride children’s toothpaste can be introduced, following current Australian guidelines. Children need help brushing until about eight years old, as they lack the coordination to clean thoroughly on their own. Many parents find it easiest to brush from behind, with the child’s head tilted back slightly.
Make brushing fun. Songs, timers, sticker charts and letting children choose their own toothbrush can turn a nightly battle into a game.
The First Dental Visit
Many dental professionals recommend a first visit by the child’s first birthday or within six months of the first tooth appearing. Early visits are often short and relaxed, focusing on checking development, offering advice and helping the child become comfortable in the dental chair.
Choosing a family-friendly dentist who enjoys working with children helps build positive associations from the start, which makes future visits easier for both parent and child. Some clinics offer a ride in the chair, a look at the instruments and small rewards to keep things fun.
Speak positively about visits at home and avoid using words like pain or needle, even when reassuring. Picture books and short videos about going to the dentist can help young children know what to expect, and bringing an older sibling along to watch their check-up often makes the younger one curious rather than nervous.
Food and Drink Choices
Diet has an enormous influence on dental health. Frequent snacking on sugary or sticky foods exposes teeth to acid attacks throughout the day. Fruit juice, cordial, soft drinks and sports drinks are significant sources of sugar and acid.
Water is the best drink for teeth. Milk is a good choice at meal times. Healthy snacks include cheese, vegetables, plain yoghurt and fresh fruit in moderation. Keeping sweet treats to meal times, rather than grazing throughout the day, reduces the time teeth are exposed to sugar.
School-Age Children
As children grow, their adult teeth begin to emerge, typically starting with the first permanent molars around age six. These molars appear behind the baby teeth, so parents sometimes do not realise they are permanent. They are especially vulnerable to decay because of their deep grooves.
Fissure sealants, a protective coating applied to the chewing surfaces of molars, can help prevent decay. Ask your dental team whether they are recommended for your child.
Sport and Mouthguards
Children involved in contact sports such as football, rugby, hockey, basketball and martial arts should wear a properly fitted mouthguard. Custom-fitted mouthguards made by a dental professional offer better protection and comfort than over-the-counter options.
Know what to do if a tooth is knocked out. For adult teeth, handle the tooth by the crown, rinse briefly in milk if dirty, try to place it back in the socket or keep it in milk, and see a dentist immediately. Baby teeth should not be replanted.
Teenagers and Independence
Teenagers often become less diligent about brushing as they gain independence. Busy schedules, sugary energy drinks, braces and changing diets can all affect oral health. Encourage good habits by keeping supplies stocked, discussing the effects of sugary and acidic drinks, and continuing regular dental visits.
Orthodontic assessment may be recommended during these years if teeth are crowded or the bite is misaligned.
The Child Dental Benefits Schedule
Eligible Australian children may receive basic dental services under the Child Dental Benefits Schedule, which covers services such as check-ups, X-rays, cleans, fissure sealants and fillings up to a set amount over two consecutive calendar years. Check eligibility through Services Australia.
Setting Up a Lifetime of Healthy Habits
Children learn by watching. When parents brush, floss, choose water and attend regular dental visits, children absorb those habits as normal. Healthy teeth support healthy eating, clear speech and confident smiles, and the habits formed in childhood often last for life. With consistent care, today’s toddlers can grow into adults who have never known what a toothache feels like.
