Giving an infant a sugary drink at nap or nighttime is harmful because during sleep, the flow of saliva decreases, allowing the sugary liquids to linger on the child's teeth for an extended period of time. If left untreated, decay can result, which can cause pain and infection. Severely decayed teeth may need to be extracted. If teeth are infected or lost too early due to baby bottle tooth decay, your child may develop poor eating habits, speech problems, crooked teeth and damaged adult teeth. Healthy baby teeth will usually result in healthy permanent teeth.
