Baby teeth start to break through the hums around 6 months. But it is important to start good oral care even before the first tooth comes in. From healthy gums come healthy teeth.
Kids have all their baby teeth by age 3. These are called primary teeth. Baby teeth start falling out around age 6; that' when the permanent, or adult teeth start coming in. Gaps between baby teeth are normal, They make room for the permanent teeth. Most permanent teeth come in by age 13.
