As soon as a baby’s first teeth appear—usually by age six months or so—the child is susceptible to decay. This condition is often referred to as Baby Bottle Tooth Decay or Early Childhood Caries (cavities). In some unfortunate cases, infants and toddlers have experienced severe tooth decay that has resulted in dental restorations or extractions. The good news is that decay is preventable.

Decay occurs when sweetened liquids are given and are left clinging to an infant’s teeth for long periods. Many sweet liquids cause problems, including milk, formula and fruit juice. Bacteria in the mouth use these sugars as food. They then produce acids that attack the teeth. Each time your child drinks these liquids, acids attack for 20 minutes or longer. After many attacks, the teeth can decay.

It’s not just what you put in your child’s bottle that causes decay, but how often — and for how long a time. Giving your child a bottle of sweetened liquid many times a day isn’t a good idea. Allowing your child to fall asleep with a bottle during naps or at night can also harm the child’s teeth.
