When will your baby start to get his or her first teeth? And when will those baby teeth start to get replaced by permanent teeth? Check out the chart below to see a timeline for your child’s dental development.

Primary and permanent teeth are both important to your child’s ability to eat, speak, and,of course, smile!  You can expect to see the first baby tooth make its appearance around 6 months of age, although it will take until your child is about 2-3 years old for them to have all 20 baby teeth erupted. Your child will keep those 20 baby teeth until they’re around 6 or 7 years old, when you’ll start to see the first permanent teeth erupt.

The American Academy of Pediatric Dentistry recommends that children have their first dental checkup by age one, or within 6 months of the appearance of the first tooth. This allows the pediatric dentist to start preventative strategies as well as screen for early tooth decay.

The American Academy of Orthodontics recommends that children have their first visit with an orthodontist by age 7. This allows the orthodontist to evaluate the child’s growth and development, and make recommendations for any necessary interventions at the proper time.
