Teething is different for different babies, but there is a general pattern of the order and timing of the emergence of the twenty baby teeth. If your baby teeths differently, don't worry. You can see a pediatrician or a dentist and ask questions, but it is overwhelmingly likely that all of your baby's teeth will come in their own time. It is unusual for a baby to cut her first two teeth after the age of one, but it does happen, and the baby then goes on to grow a full set of teeth. On the other end of the spectrum, very rarely some babies are born with one or more teeth already grown in. But most commonly, teething occurs in the following pattern.
Between six and eight months, the baby's first four incisors come in. These are the two middle teeth on the top and bottom. The bottom ones usually come in first. The other incisors, two more on top and two more on bottom, come in between the seventh and ninth months. Next, the lower and upper first molars (four teeth total) emerge between the tenth and 14th months. The molars are larger than incisors or canines, and are used for chewing. The canines, the pointed teeth, appear after the first molars, when the child is between 15 and 18 months of age. And last, the second molars, in the back of the mouth, usually emerge when the child is around two years old, or any time between the ages of two and three.
Once your child has all twenty baby teeth, she will keep them until around the age of six, when her permanent, adult teeth will begin to emerge, making the baby teeth become loose and eventually fall out to make way for the permanent teeth.
