Age of six months.
The first baby teeth (also known as primary teeth) to come in are usually the lower central incisors around the age of six months. The last baby teeth to show up are the upper second primary molars, and they appear between 30 and 36 months of age. There are normally 20 baby teeth by the time a child reaches age 3. These primary teeth then remain unchanged for about three years. Not much happens to the baby teeth between 3 and 6 years of age. Between 6 and 8 years however, there is a flurry of activity as kids normally lose eight primary teeth in rapid succession A child's baby teeth (primary teeth) begin to loosen and fall out to make room for permanent teeth at about age 6. The first baby teeth to fall out are typically the two bottom front teeth (lower central incisors) and the two top front teeth (upper central incisors), followed by the lateral incisors, molars and canines. Molars typically fall out between ages 9 and 12 and are replaced by permanent teeth by about age 13. Baby teeth usually stay in place until they are pushed out by permanent teeth. If a child loses a baby tooth early as a result of tooth decay or an accident, the teeth beside it might drift into the empty space. The following chart shows when your child's primary teeth (also called baby teeth or deciduous teeth) should erupt and shed. Eruption times vary from child to child. As seen from the chart, the first teeth begin to break through the gums at about 6 months of age. Usually, the first two teeth to erupt are the two bottom central incisors (the two bottom front teeth). Next, the top four front teeth emerge. The complete set of primary teeth is in the mouth from the age of 2 ½ to 3 years of age to 6 to 7 years of age. Other primary tooth eruption facts: 1  A general rule of thumb is that for every 6 months of life, approximately 4 teeth will erupt. Babies' teeth begin to develop before they are born, but in most cases don't come through until they're between 6 and 12 months old. Most children have a full set of 20 milk or baby teeth by the time they're three years old. When they reach five or six, these teeth will start to fall out, making way for adult teeth. By the age of 12 to 14, most children have lost all their baby teeth and have their adult teeth. There are 32 adult teeth in total, 12 more than in the baby set. A: There's a huge range of normal when it comes to losing baby teeth. Although most children lose their first tooth at 5 or 6, some start as young as 4, and others won't get to meet the Tooth Fairy until 7. Your child will usually be the first to know when a tooth is loose because she can feel it moving.  Your child's jaw and facial bones grow, creating space between the primary teeth for the permanent, adult teeth to come in (AAP 2009) . Your child's first teeth usually start to fall out at around the age of six or seven, and begin to be replaced by their permanent teeth (Anderson 2004, Nield el al 2008) . Ask for help if ... If your toddler doesn't show any signs of a tooth by his first birthday, mention it to your health visitor.  After a two-year break (about age 10), the next four baby teeth to be lost are the lower canines and upper first molars. These are typically followed around age 11 by the lower first molars. The lower second molars tend to be lost about the same time as the upper canines and second molars. There are normally 20 baby teeth by the time a child reaches age 3. These primary teeth then remain unchanged for about three years. Not much happens to the baby teeth between 3 and 6 years of age. Some children lose their first tooth as early as 4 or as late as 7. Generally, the younger the child was when the teeth came in, the earlier they fall out. It's possible for kids to lose a baby tooth too early, before the permanent tooth is ready to erupt, because of an accident or dental disease. If your child is a worrier, you can reassure him that he probably won't feel anything. First in, first out. A child's 20 baby teeth, which typically come in by age 3, usually fall out in the order in which they came in. That means the lower center teeth (lower center incisors) are usually the first to go, around age 5 or 6 Losing baby teeth is seldom as painful a process as teething. If your 5- or 6-year-old complains of pain in the back of his mouth, it's probably the 6-year molars coming in. (He has no baby teeth there to fall out first). If your child is a worrier, you can reassure him that he probably won't feel anything. First in, first out. A child's 20 baby teeth, which typically come in by age 3, usually fall out in the order in which they came in.
