What are the Causes of baby bottle tooth decay?

Bottles containing milk, formula, juices, and sugar water continuously bathe an infant’s mouth with sugar. The bacteria such as streptococcus mutans, lactobacillus use sugar and produce acids. These acids destroy the enamel of baby teeth. Sugars, bacteria and time are the key factors for the cavity formation.

  • Decay happens when sweetened liquids or those with natural sugars like milk, formula and fruit juice cling to infants teeth for a long time. Bacterial reaction on these produces acids. Acids demineralize the enamel leads to tooth decay.
