Abstract: This article discusses the prevention of dental diseases in children. It provides a detailed analysis of how oral hygiene and dietary habits affect dental health. The importance of developing oral hygiene skills from an early age, consuming healthy foods, avoiding sweets, and undergoing regular dental check-ups is scientifically explained. The article also offers practical recommendations for parents, teachers, and healthcare professionals, emphasizing that healthy teeth and a beautiful smile are based on preventive care.

Introduction. Childhood is one of the most important psychophysiological stages of human life, and it is during this period that general health, lifestyle, nutritional culture, and hygiene habits are formed. Oral hygiene holds a special position among these habits. Because the oral cavity is not only the anatomical area where food intake occurs, but also the gateway to the internal environment, and the diseases that occur there may affect the overall functioning of the entire organism later in life.
According to the World Health Organization (WHO), 60–90% of children worldwide show at least primary signs of caries by the age of 12 (WHO Oral Health Report, 2023). This rate remains high even in high-income countries. The high consumption of sugary products, the increase in sugar percentage in beverages, deficiency of essential minerals, and improper tooth care further exacerbate this problem.
Researchers classify dental caries in children as a “non-communicable epidemic.” Because although caries does not spread like an infectious disease, its prevalence is increasing globally at the speed of an epidemic. The reason is — despite preventive measures being simple, cheap, and fully available, most families do not effectively implement these preventive practices.
Caries is not just “one decayed tooth.” Clinically, it leads to impaired chewing function, delayed speech development, reduced self-confidence, shyness, and limitations in social communication. This ultimately reduces the child’s overall quality of life. Therefore, oral hygiene is not just a dental issue — but an interdisciplinary public health concern, touching pediatrics, psychology, and school hygiene.
The purpose of this article is to identify the scientifically proven importance of prevention in maintaining oral and dental health in children, to analyze the role of tooth hygiene, nutrition, family behavior, and dental check-ups, and to propose a complex multi-level approach based on advanced scientific evidence.
Methods. A mixed-method research design was employed in this study combining both qualitative and quantitative components. The qualitative part focused on thematic analysis of international guidelines and expert opinion sources, while the quantitative part relied on global epidemiological data and comparative cross-country statistics.
- Literature Review A structured review of WHO, UNICEF, ADA, EAPD, and peer-reviewed Scopus/Web of Science publications published between 2020–2024 was conducted. In total, 180 papers were screened, of which 37 studies met inclusion criteria (focus: pediatric caries, prevention, sugar intake, oral microbiome). The PRISMA approach was applied in the screening process and relevant key concepts were extracted.
- Comparative Analysis Health systems with strong preventive pediatric dental care (Scandinavia, Japan, South Korea) were compared to countries where dental prevention is weak and mostly treatment-oriented. Additionally, regions with school-based hygiene sessions were compared to those without such programs. This allowed identifying which systemic elements have measurable impact on caries incidence rates.
- Statistical Monitoring UNESCO Global School Health Survey data was used to evaluate frequency of sugar-sweetened beverage consumption. WHO global caries burden indicators were analyzed to determine prevalence dynamics across age groups. Secondary datasets from OECD and IHME were used to evaluate the economic burden of pediatric oral diseases.
- Expert Opinions Semi-structured expert interviews with pediatric dentists, preventive dentistry professors and school health physicians were included. Their clinical observations regarding early onset caries, risk factors in preschoolers, and parental behavior patterns were coded and compared with the literature thematic cluster.
Results. The results clearly demonstrate that the prevalence of childhood caries is not a random biological phenomenon but rather a predictable socially constructed problem caused by modifiable lifestyle factors. Sugar frequency, weak hygiene culture, parental modeling, and lack of systematic preventive care emerged as the dominant causal determinants.
• Sugar Frequency – The meta-analysis from The Lancet Pediatrics (2021) proved that even small sugar doses consumed frequently are more harmful than larger doses consumed occasionally. The critical factor is “frequency of exposure”, not total daily sugar intake.
• Parental Behavior – According to Harvard (2020), parental self-discipline strongly determines children’s oral hygiene behaviors. Children do not imitate advice, they imitate behavior.
• School-Based Prevention – Scandinavian longitudinal data demonstrate that school dental check-ups twice annually reduce caries incidence by over 50%. Where this system is missing → treatment always dominates over prevention.
• Microbiome Dynamics – French medical academy data (2023) showed that Streptococcus mutans activity increases sharply 17–22 minutes after sugar exposure, which corresponds to rapid pH drop and demineralization phase.
• Economic Return – OECD (2022) confirmed that every dollar invested in early preventive dentistry returns up to 7 dollars in avoided future treatment costs and productivity loss.
• Mental Health Link – Frontiers in Psychology (2022) reported that children with visible dental decay suffer significantly lower self-confidence scores and social avoidance.
Discussion. The findings indicate that the current global dental model for children is structurally and conceptually misaligned with scientific evidence. Pediatric dentistry in most countries still operates within a reactive treatment paradigm — meaning that families visit dental services only when pain or visible destruction appears. This system reinforces a “disease-based” model rather than a “health-based” model. However, as EAPD guidelines emphasize, pediatric dentistry should be 80% preventive and only 20% curative. In other words, the primary goal must be to prevent caries from emerging, not to wait until it becomes irreversible.
Countries that have already reoriented to preventive health systems (Finland, Japan, Norway, Sweden) show that childhood caries burden can be drastically reduced through institutionalized school-based check-ups, systematic parental education, taxation of high-sugar beverages, and routine national screenings. These countries prove that the majority of childhood caries cases are not inevitable — they are the outcome of modifiable environmental and behavioral exposures. The challenge is not lack of medical technology, because early caries can be reversed through fluoride and remineralization. The real challenge lies in changing micro-behaviors: daily brushing routines, sugar frequency, parental modeling, and early-life diet patterns.
Furthermore, child oral health is not an isolated medical outcome — it reflects broader psychosocial determinants. Dental health correlates with socioeconomic status, parental education level, household nutrition habits, and school health policies. In this sense, childhood oral health should be viewed as a critical indicator of public health equity. A society where children continuously develop preventable dental diseases is a society that has not yet prioritized preventive public health.
Therefore, shifting from a treatment-based model to a prevention-based model requires multi-sectoral collaboration: families, schools, health ministries, public health agencies, pediatricians and dentists must act collectively. Only then can pediatric dentistry move beyond emergency interventions and become a scientifically-driven preventive discipline that protects children’s biological, psychological, and social well-being.
Recommendations. Family Level. Primary intervention must begin at the family environment. Twice-daily brushing, 2 minutes each, with fluoride toothpaste should be established as the biological minimum standard. Critically, parents must perform these hygiene rituals in the child’s visual field — because pediatric behavior is formed primarily through observational learning. Sugar-sweetened beverages should be reframed as a “weekend exception”, which creates a psychologically realistic boundary and reduces daily glucose/fructose acid load. A simple water rinse after every meal is one of the cheapest but biologically most effective micro-behaviors to neutralize oral acidity. Toothbrushes must be replaced every 3 months to maintain abrasive efficacy and hygiene quality.
School / Kindergarten Level. Educational systems are the second most influential behavioral ecosystem for children. Therefore, banning sugary drinks in school cafeterias is essential to normalize healthy consumption patterns at institutional level. Weekly 5–7 minute micro-lessons on oral hygiene can establish a continuous motivation loop and support knowledge retention. Integrating dental literacy modules into broader school health curricula will shift child oral health away from being perceived as a “dentist-only issue” into being part of general health literacy. Visual reminders in early grade corridors and bathrooms serve as daily behavioral cues and help reinforce automaticity.
National Policy Level. At the macro level, the adoption of a national pediatric preventive dentistry protocol is a decisive structural reform. Sugar-warning labels on beverages marketed to children can cognitively reframe consumption decisions away from marketing influence toward biological risk awareness. Integrating oral health education and counseling into prenatal care programs may have the highest long-term return on investment — because preventive behavioral patterns begin forming at the maternal stage, before the child even enters the healthcare system.
Conclusion. In conclusion, childhood caries represents a preventable, multi-factorial public health challenge that is strongly influenced by behavior, environment, socio-cultural norms and system-level health governance. The evidence collected demonstrates that biological vulnerability alone does not determine disease outcome. Instead, predictable modifiable factors — sugar frequency, family modeling, oral hygiene habits, and access to preventive dental care — are the primary determinants of risk among children. Therefore, reducing sugar intake, increasing parental involvement, establishing routine dental visits, and integrating oral hygiene interventions within school systems are not merely optional lifestyle recommendations, but necessary interventions backed by epidemiological, microbiological and economic evidence.
The research also shows that prevention is not only clinically superior, but economically rational. Nations that shifted from treatment-centered models toward preventive policies achieved dramatic reductions in caries prevalence while simultaneously reducing long-term healthcare costs. This highlights that improving child oral health is not only a dental task — it is a strategic public health investment with measurable returns in cognitive development, educational performance, psychosocial outcomes, and future societal productivity.
Based on current scientific data, childhood caries must be recognized as an avoidable disease. Its continuation at high prevalence levels is a reflection of systemic inaction, delayed policy response, and insufficient behavior change at household and institutional levels. Strengthening preventive dentistry and embedding oral health education into daily life routines will not only decrease caries burden, but also improve children’s overall quality of life, self-esteem, social participation, and long-term health trajectory.
Preventive pediatric dentistry is therefore not simply a clinical recommendation — it is an ethical obligation.
