Dental caries (more commonly known as tooth decay or cavities) is the most common chronic childhood disease. The transition from breastfeeding or bottle feeding can be a challenging time for both parent and infant. Importantly, it represents a time where the risk for development of dental caries begins with the eruption of the first baby teeth. Transition from breastfeeding/bottle-feeding usually coincides with the introduction of solid foods that may contain substances (i.e. sugars &amp; other carbohydrates) that can cause dental caries. The consumption of cow’s milk and other non-breast milk beverages (i.e. juices) at 6 weeks to 12 months of age significantly contributes to dental caries at 5 years. There is a relationship between prolonged and inappropriate bottle use and increase in dental caries and as such, it is recommended that infants be encouraged to drink from a cup by their first birthday and be weaned from the bottle by 12–14 months of age. Breastfeeding cessation is dependent upon the infant and mother. Pacifier may be used as a means of soothing or distracting the infant. Due to the risk for dental caries, dipping pacifiers in sweetened liquids (i.e. sugar water, juice etc.) is discouraged.
