Sometimes parents tell me that they don't brush their baby's or child's teeth and don't worry about cavities because "they are just going to loose them anyway" !! Baby teeth serve important purposes such as helping the child to speak normal and clear, and to chew naturally. Baby teeth also hold a place for permanent teeth to come in properly. Children with cavities eat poorly, stop smiling, and don’t learn properly. Tooth decay is an infection that does not heal without treatment. If cavities are not treated, children can develop infections severe enough to require emergency room treatment and their adult teeth may be permanently damaged. Remember, rotten children's teeth aren't as valuable as healthy ones plus it's kind of gross. See some pictures of what happens if you don't brush your teeth!
