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.
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.
Starting to visit a dentist
By the time your child is 6 months of age, your doctor should assess the likelihood of your child having future dental problems. This may include a dental exam of the mother and her dental history, as the condition of her teeth can often predict her child’s teeth. If the doctor thinks your child will have dental problems, be sure your child sees a dentist by his or her first birthday or 6 months after the first primary teeth appear, whichever comes first. After your first visit, schedule regular visits every 6 months or as your dentist recommends.
Experts recommend that your child see a dentist by your child’s first birthday. Babies with dental problems caused by injury, disease, or a developmental problem should be seen by a children’s (pediatric) dentist right away. If these dental problems are not limited to the surfaces of the teeth, your baby should also be seen by a children’s doctor (pediatrician) or your family doctor.
