Bottle rot, medically known as early childhood caries (ECC), is tooth decay impacting infants and young children. This condition develops rapidly and affects primary teeth, which are crucial for a child’s eating, speech development, and proper alignment of future adult teeth. ECC results from bacteria in the mouth producing acids that erode tooth enamel.
Identifying the Visual Signs
The initial signs of bottle rot can be subtle, often appearing as dull, chalky white spots or lines on the tooth surface, especially near the gum line. These early lesions are most commonly observed on the upper front teeth, which are particularly susceptible due to prolonged exposure to liquids during feeding. As the decay progresses, these white spots can transition to yellow, brown, or even black discoloration on the enamel.
In more advanced stages, the affected enamel may appear pitted, rough, or crumbling. Holes or cavities may also become visible in the tooth surface. The decay can spread from the upper front teeth to other primary teeth if not addressed. Children might also experience tooth sensitivity, pain when consuming hot, cold, or sweet foods, or have swollen and bleeding gums in severe cases.
Understanding the Causes
Bottle rot results from frequent, prolonged exposure of a child’s teeth to sugary liquids. This often occurs when infants or toddlers fall asleep with a bottle containing milk (including breast milk), formula, juice, or other sweetened beverages. Sugars in these liquids feed mouth bacteria, which then produce acids that demineralize tooth enamel.
During sleep, saliva production, which normally washes away food particles and neutralizes acids, significantly decreases. This reduced flow allows sugary liquids to pool around the teeth for extended periods, intensifying the acid attack. Frequent snacking or sipping on sugary drinks throughout the day also increases the risk, providing continuous exposure to sugars and acids. Poor oral hygiene practices further contribute by allowing plaque and bacteria to accumulate on tooth surfaces.
Strategies for Prevention
Preventing bottle rot involves adopting oral hygiene and feeding practices from an early age. Avoid letting babies fall asleep with a bottle containing anything other than water. If a child needs a bottle for comfort at bedtime, it should only contain plain water. Limit sugary drinks, including fruit juice, especially during the first two years.
Introducing a cup around 12 months helps transition children away from bottles and reduces prolonged exposure to liquids around the teeth. Oral hygiene should begin even before teeth erupt by gently wiping the baby’s gums with a clean, damp cloth or gauze after feedings. Once the first tooth appears, brush twice daily with a soft-bristled, infant-sized toothbrush and a smear of fluoride toothpaste, about the size of a grain of rice. The American Academy of Pediatric Dentistry recommends scheduling a child’s first dental visit around their first birthday or within six months of the first tooth erupting, whichever comes first.
