Practical tips to help children build brushing habits in a calm and positive way.
Tooth brushing is one of the pillars of oral health and paediatric oral health. However, for many parents, this moment turns into a daily challenge. Refusal, crying or distraction are common behaviours, especially between the ages of 2 and 6. The good news is that there are simple strategies, backed by clinical experience and scientific evidence, often recommended by a paediatric dentist, that help build oral hygiene habits without conflict.
According to the Directorate-General for Health, dental caries remains one of the most frequent chronic diseases in childhood. Studies indicate that correct brushing with fluoridated toothpaste, twice a day, can significantly reduce the risk of caries. Creating a positive routine from an early age makes all the difference in the child's oral development, a guiding principle in any consultation with a paediatric dentist.
Why do children resist brushing?
Resistance to brushing is part of childhood development. Between the ages of 2 and 4, children seek to assert their autonomy. If they associate brushing with imposition or discomfort, the likelihood of opposition increases.
Sensory factors also play an important role. Some children are more sensitive to the taste of toothpaste, the texture of the toothbrush bristles or the feeling of water in their mouth.
Understanding these variables allows the approach to be adjusted on an individual basis, something that can be guided by a paediatric dentist during clinical evaluation.
Simple Tricks Recommended by a Paediatric Dentist
1. Establish consistent schedules
Brushing should always take place at the same times of the day. Predictability reduces resistance and reinforces the habit, which is a standard recommendation from any paediatric dentist in a preventive context.
2. Encourage active participation
Allowing the child to choose their toothbrush or participate in the process increases commitment. An adult must supervise and, if necessary, complete the brushing to ensure it is effective, at least until the age of 10.
3. Use playful strategies
Songs lasting approximately two minutes help to meet the recommended time. Creating short stories or positive challenges can increase motivation, a strategy often suggested by a paediatric dentist to improve adherence to oral hygiene.
4. Apply the correct amount of toothpaste
Up to 3 years of age, an amount equivalent to a grain of rice is recommended. From that age onwards, a pea-sized portion. The fluoride concentration should be adjusted to the child's age and individual caries risk, an assessment that should be made in consultation with a paediatric dentist.
5. Reinforce positive behaviours
Specific praise has a proven impact on children's behaviour. Phrases like “You brushed your back teeth really well” are more effective than criticism.
Common errors that compromise children's brushing
As important as knowing what to do is understanding what to avoid. Some behaviours, even if well-intentioned, can make it harder to build a healthy habit. For example, using brushing as a punishment associates the moment with a negative experience. Allowing a child to regularly fall asleep without brushing their teeth significantly increases the risk of tooth decay, especially because saliva flow decreases during sleep.
Another common mistake is the excessive use of toothpaste. Quantities higher than those recommended do not increase effectiveness and can elevate the risk of unnecessary fluoride ingestion. It is also common to undervalue baby teeth, assuming that "they will fall out". However, deciduous teeth are essential for chewing, speech development, and maintaining space for permanent teeth.
The importance of fluoride in preventing childhood tooth decay
Fluoride strengthens tooth enamel and reduces demineralisation caused by the acids produced by plaque bacteria. Scientific recommendations advocate the use of fluoridated toothpaste from the eruption of the first tooth.
During regular appointments, caries risk is assessed and additional measures, such as fissure sealants or topical fluoride applications, may be recommended. These decisions must always be individualised and guided by a paediatric dentist, taking into account the specific characteristics of each child.
Diet and caries risk: what parents should know
The prevention of childhood caries does not only depend on brushing. The frequency of sugar intake plays a decisive role. It is not just the amount of sugar that matters, but above all the regularity with which the child consumes it throughout the day.
Frequent snacks rich in simple carbohydrates, juices or sugary drinks keep the oral pH low for prolonged periods, promoting the demineralisation of the enamel. For this reason, it is recommended to limit the consumption of sugary foods to specific times and to avoid intake after brushing.
Nutritional education is an integral part of the consultation with the paediatric dentist. An effective preventive approach integrates proper oral hygiene and balanced eating habits.
Clinical curiosity
Night-time brushing is of particular importance because saliva flow decreases during sleep. Lower saliva production means less capacity to neutralise acids. Therefore, brushing before going to bed should not be neglected and the child should not consume any food, liquid or solid afterwards.
The role of the paediatric dentistry consultation
The first consultation should take place by the first year of life or after the eruption of the first tooth. Regular monitoring helps to prevent caries, monitor growth and guide parents on diet and oral hygiene habits.
Early intervention reduces the need for more complex treatments in the future and contributes to a positive relationship between the child and the paediatric dentist.
