The development of healthy oral habits begins in infancy, with the first few years of life being crucial for setting the foundation for long-term oral health. Early childhood caries (ECC), a common and preventable dental issue, can start as early as the eruption of the first teeth. Preventing oral health problems in infancy is essential for reducing the risk of more severe dental issues later in life. Understanding the risk factors associated with dental problems in infancy is key to developing effective prevention strategies [1].

This article aims to review the primary risk factors for dental issues in infancy and provide practical guidelines for oral health care during this critical developmental period.

Risk factors for dental issues in infancy

Poor Nutrition

One of the most significant risk factors for dental problems in infants is improper nutrition, especially with regard to sugary foods and drinks. Infants who are frequently exposed to sugary liquids, including juice, milk, and formula, are at a higher risk of developing dental decay as these sugars contribute to plaque formation, which leads to tooth decay [2].

• Breastfeeding vs. bottle-feeding: Extended bottle-feeding, especially when the bottle contains sugary liquids, increases the risk of ECC. This practice, often referred to as "bottle tooth decay," can lead to severe enamel erosion and cavities in the early years.
• Introduction of solid foods: The introduction of solid foods also plays a role. High-sugar foods such as juices and sweetened cereals should be avoided or minimized during the infant's first year to reduce the risk of cavities.

Inadequate oral hygiene practices

Infants are often not provided with adequate oral care, which can contribute to the development of dental issues such as ECC. Proper oral hygiene practices should begin even before the first tooth erupts [3].

• Early cleaning: Parents should begin cleaning their infant's gums with a soft, damp cloth or a baby toothbrush as soon as possible. This practice helps remove plaque buildup from milk residue and establishes the habit of oral care.
• Teething and cleaning: Once the first teeth emerge, brushing with a soft-bristled toothbrush and a small amount of fluoride toothpaste can help prevent plaque buildup and decay.

Genetic factors

Genetics can play a significant role in an infant’s susceptibility to dental problems. Certain genetic conditions may make infants more prone to oral health complications. For instance, conditions like gametogenesis imperfect, which affects the development of enamel, can increase the risk of tooth decay and sensitivity.

• Inherited Dental Conditions: Some children may be born with teeth that are more prone to decay or have thinner enamel. Genetic factors related to saliva production and pH balance can also influence the risk of developing dental issues [4].

Early childhood exposure to harmful habits

Early childhood exposure to certain harmful habits can significantly affect oral health. These habits include thumb sucking, pacifier use, and prolonged bottle feeding.

• Thumb sucking and pacifier use: While these behaviors are common in infancy, prolonged thumb sucking or pacifier use beyond the age of 2 can cause misalignment of teeth and interfere with the development of a child’s bite.
• Nighttime feeding: If a baby is put to bed with a bottle, the liquid can pool in the mouth and promote bacterial growth, leading to cavities. The habit of sucking on a bottle while sleeping should be discouraged to prevent these issues.

Lack of regular dental check-Ups

Infants who do not receive early dental visits may experience undetected oral health issues. The American Academy of Pediatric Dentistry recommends that infants have their first dental check-up by age one or within six months of the eruption of their first tooth. These early visits allow pediatric dentists to monitor oral development, offer preventive care, and guide parents on best practices for maintaining oral hygiene [5].

• Early detection: Regular visits help in detecting issues like early childhood caries, teething problems, or alignment issues before they progress.

Environmental factors

Environmental factors, such as socioeconomic status, access to healthcare, and parental education, significantly influence infant oral health.

• Socioeconomic status: Infants from lower socioeconomic backgrounds are more likely to have limited access to dental care, which increases their risk of oral health problems.
• Parental education: Caregiver knowledge about infant oral care is crucial in preventing dental problems. Parents who are unaware of proper oral hygiene practices may unknowingly contribute to the development of oral issues in their children.

Discussion

Infancy is a critical time for setting the foundation of oral health, and the risks associated with dental problems are influenced by multiple factors. While some risk factors, such as genetics, are out of the control of parents, many others—such as poor nutrition, inadequate oral hygiene, and harmful habits—can be addressed through early intervention and education.

Preventive care, including early dental visits, proper oral hygiene practices, and a healthy diet, is essential in reducing the risk of dental issues such as early childhood caries. Public health initiatives aimed at educating caregivers and providing accessible dental care services are vital for reducing the burden of dental problems in infancy [6-10].

Conclusion

Dental issues in infancy, particularly early childhood caries, are largely preventable through proactive care and education. Understanding and addressing the risk factors for dental problems in infants, including nutrition, oral hygiene, and harmful habits, can lay the foundation for a lifetime of healthy oral development. Early intervention, regular dental check-ups, and caregiver education are essential to ensuring that infants grow up with good oral health.
