A child’s dental care really starts with his or her mother’s healthy pregnancy, because baby teeth begin to form before birth. If you are pregnant, make sure to eat a balanced, nutritious diet and get an adequate amount of vitamins and minerals. It’s important for pregnant women to have a complete dental exam and have any cavities or gum disease treated.
Your child’s first teeth usually begin to break through the gums (erupt) at about 6 months of age, although the timing varies among children. All of the 20 primary teeth should come in between the ages of 6 months and 3 years. Your child will lose his or her primary teeth between the ages of 6 and 11. For more information, see the topic Teething.
Your child’s first permanent teeth (molars) usually erupt behind the primary teeth at about age 6. The last permanent teeth usually erupt between the ages of 12 and 21.
