Tooth brushing is one of the pillars of oral health and children's oral health. However, for many parents, this moment becomes a daily challenge. Refusals, crying, or distraction are common behaviors, especially between the ages of 2 and 6. The good news is that there are simple strategies, supported by clinical experience and scientific evidence, often recommended by a pediatric dentist, that help create habits of oral hygiene without conflict.

According to the Directorate-General for Oral Health, dental caries remains one of the most common chronic diseases in childhood. Studies indicate that proper brushing with fluoride toothpaste, twice a day, can significantly reduce the risk of caries. Creating a positive routine from an early age makes a big difference in the child's oral development, a broad guideline in consultation with any pediatric dentist.

Why do children resist brushing?

Resistance to brushing is part of child development. Between the ages of 2 and 4, a child seeks to assert independence. If brushing is associated with imposition or discomfort, the likelihood of opposition increases.

Sensory factors also play an important role. Some children may be more sensitive to the taste of toothpaste, the texture of the brush bristles, or the sensation of water in their mouth.

Understanding these variables allows for an individualized approach, something that can be guided by a pediatric dentist during the clinical evaluation.

Simple tricks recommended by a Pediatric Dentist

1. Establish consistent times

Brushing should always occur at the same times of day. Predictability reduces resistance and reinforces the habit, making this a common recommendation from any pediatric dentist in a preventive context.

2. Encourage active participation

Allowing the child to choose the toothbrush or participate in the process increases commitment. The adult should supervise and, if necessary, complete the brushing to ensure that it is effective, at least until the age of 10.

3. Use playful strategies

Songs lasting approximately two minutes help meet the recommended time. Creating little stories or positive challenges can increase motivation, a strategy frequently suggested by a pediatric dentist to improve adherence to oral hygiene.

4. Apply the correct amount of toothpaste

Up to 3 years old, a quantity equivalent to a grain of rice is recommended. From that age, a portion the size of a pea. The fluoride concentration should be adjusted according to age and individual caries risk, an assessment that should be made during a consultation with the pediatric dentist.

5. Reinforce positive behaviors

Specific praise has a proven impact on child behavior. Phrases like “You brushed the back teeth very well” are more effective than criticism.

Common mistakes that compromise children's brushing

As important as knowing what to do is understanding what should be avoided. Some behaviors, even if well-intentioned, can hinder the creation of a healthy habit. For example, using brushing as a form of punishment associates the moment with a negative experience. Allowing the child to regularly fall asleep without brushing their teeth significantly increases the risk of cavities, especially since saliva flow reduces during sleep.

Another frequent mistake is the excessive use of toothpaste. Amounts exceeding the recommended amounts do not increase effectiveness and can raise the risk of unnecessary fluoride ingestion. It is also common to underestimate baby teeth, assuming that “they will fall out.” However, primary teeth are essential for chewing, speech development, and maintaining space for permanent teeth.

The importance of fluoride in preventing childhood cavities

Fluoride strengthens dental enamel and reduces demineralization caused by acids produced by plaque bacteria. Scientific recommendations advocate for the use of fluoride toothpaste from the eruption of the first tooth.

During regular check-ups, the risk of cavities is assessed, and additional measures, such as sealants or topical fluoride applications, may be recommended. These decisions should always be individualized and guided by a pediatric dentist, taking into account the specific characteristics of each child.

Diet and cavity risk: what parents should know

Preventing childhood cavities does not only depend on brushing. The frequency of sugar intake plays a determining role. It is not only the amount of sugar that matters, but especially how regularly the child consumes it throughout the day.

Frequent snacks rich in simple carbohydrates, juices, or sugary drinks keep oral pH low for prolonged periods, favoring demineralization of enamel. For this reason, it is recommended to limit the consumption of sugary foods to specific moments and avoid intake after brushing. 

Nutritional education is an integral part of the appointment with the pediatric dentist. An effective preventive approach includes appropriate oral hygiene and balanced eating habits.

Clinical curiosity

Nighttime brushing assumes special importance because saliva flow decreases during sleep. Lower saliva production means lower acid neutralization capability. Therefore, brushing before bed should not be neglected, and the child should not ingest any food, liquid, or solid after that. 

The role of pediatric dentistry appointments

The first appointment should occur by the first year of life or after the eruption of the first tooth. Regular follow-ups help prevent cavities, monitor growth, and guide parents on nutrition 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 pediatric dentist.
