Tooth decay can begin surprisingly early, sometimes even before a child reaches their first birthday. In the UK, around 23% of children aged 2 to 5 years old show signs of tooth decay, highlighting that this is not just a minor concern.
The good news is that early decay is almost entirely preventable through simple daily routines and careful feeding habits. Starting oral care from birth, establishing healthy habits and introducing gentle brushing when teeth emerge are the most effective ways to keep your baby’s teeth strong and healthy.

When should oral care begin?
Oral care should start long before the first tooth appears. Even newborn gums can harbour bacteria from milk, formula, or other feeds, which can eventually lead to cavities.
Gently wiping a baby’s gums with a soft damp cloth after feeds removes leftover milk and helps maintain a clean mouth. Establishing this routine also familiarises the baby with the sensation of cleaning, making the transition to brushing smoother when teeth start to appear.
How should infants be fed?
Feeding habits play a crucial role in preventing tooth decay. Frequent exposure to milk, formula or sweetened drinks, especially at night, significantly increases the risk of cavities. Studies suggest that nearly 30% of toddlers with prolonged bottle use show early signs of tooth decay, reinforcing the importance of careful feeding practices.
How should teeth be cleaned?
Once the first tooth emerges, brushing should begin immediately, twice daily. Use a soft-bristled infant-sized toothbrush with a smear of fluoride toothpaste about the size of a grain of rice.
Fluoride strengthens enamel and helps prevent decay before it begins. Brushing for just one to two minutes each time is sufficient.
At this stage, it is essential for parents to supervise and assist with brushing to ensure it is done thoroughly. Early brushing not only protects teeth but also sets up lifelong habits for dental health.
When should a dentist be involved?
A child’s first dental visit should occur by their first birthday. Early dental check-ups allow professionals to spot any developing issues and give parents personalised advice on brushing, diet and fluoride use.
Children who visit a dentist early are significantly less likely to experience severe decay later, and parents gain reassurance and practical guidance. Regular dental visits should continue every 6 months or as recommended by the dentist, to maintain healthy teeth and prevent problems from escalating.

What about diet beyond milk and formula?
As your baby begins to eat solid foods, diet continues to have a major impact on oral health. Frequent snacking on sugary foods, fruit juices or processed snacks increases the risk of decay.
Introducing water as the main drink and offering balanced meals with vegetables, protein and dairy helps to protect teeth. Encouraging your child to drink water after meals can also wash away food particles and reduce cavity risk.
How can parents reinforce healthy habits?
Consistency is key when it comes to infant oral health. Making brushing a fun and predictable part of daily routines helps children adapt without fuss.
Using positive reinforcement, songs or routines that coincide with morning and bedtime signals encourages compliance. Modelling good oral care yourself also sends a clear message. Over time, these practices become second nature, reducing the likelihood of dental issues in the future.
The bottom line
Preventing tooth decay in infants is entirely achievable with early attention, consistent brushing, careful feeding and regular dental care. By following these steps, parents can ensure their children have strong teeth, avoid pain or infections and establish the foundation for a healthy smile for life. Early intervention is key as starting before the first tooth appears can make all the difference in keeping decay at bay.
