When do children get their first teeth?
A healthy three year old child has 20 teeth. The teething process is highly variable but in general the eruption of teeth follows a set order.
Your child’s primary teeth generally make their appearance when he or she is 6 or 7 months old, though it can occur as early as birth. There are 20 primary teeth, followed by 32 permanent teeth that will eventually replace them. Your child should have all his or her primary teeth at age 3 and will keep them until age 5 or 6, when they begin to loosen and fall out. This process usually lasts until the child is 12 or 13. Primary teeth fall out because permanent teeth are pushing them, and by about age 14 children have 28 permanent teeth, plus four additional teeth, called wisdom teeth, that grow behind the permanent teeth in late adolescence.
