For one thing, primary teeth serve as guides for the eruption of permanent (adult) teeth, holding the space into which these new teeth will erupt. The crowns (tops) of the permanent teeth actually push against the roots of the baby teeth, causing them to resorb, or melt away. In this way, the adult teeth can take their proper place.
What’s more, your child’s primary teeth will be there for most of childhood, helping your child to bite, chew and speak. For the first six or so years, he or she will be relying on primary teeth exclusively to perform these important functions. Until around age 12, your child will have a mix of primary and permanent teeth. You will want to make sure those teeth stay healthy and are lost naturally — when it’s time.
Your Child’s First Teeth
Your child’s 20 baby teeth will begin to appear usually between six and nine months, though in some cases it may start as early as three months or as late as twelve months. The two lower front teeth tend to erupt first, followed by the two upper ones. The first molars come in next, followed by the canines (eyeteeth). Sometimes your baby can experience teething discomfort during this process. If so, there are courses of action to help make your child more comfortable.
Your infant’s gums and newly erupting teeth should be gently wiped after each feeding with a water-soaked gauze pad or damp washcloth. Starting at age 2, when there are more teeth in the mouth, establish a daily brushing routine with a small, soft-bristled toothbrush and no more than a thin smear of fluoridated toothpaste. Your child may need your help with this important task until about the age of 6.
