- Baby teeth (called primary teeth) start erupting around age 6 months starting with the lower front teeth (called central incisors)*
- All primary teeth usually erupt by age 3 years. There is a total of 20 primary teeth.**
- The first permanent teeth (called first molars) erupt at age 6 behind the last primary teeth.***
- All permanent teeth erupt by approximately 12-13 years of age with the exception of third molars (‘wisdom’ teeth). Wisdom teeth are usually removed during the middle to late teenage years. Your dentist will guide you on the timing for this or you can ask your orthodontist or an oral surgeon.
* The AAPD (American Academy of Pediatric Dentistry) recommends every child visit their dentist or pediatric dentist by the child’s first birthday or within 6 months from when the first tooth erupts.
** The AAO (American Association of Orthodontists) recommends getting an orthodontic consultation at age 7 years. Few kids need braces at this age but it is a good time to start monitoring permanent teeth eruption. Treatment is usually only recommended at this age for significant problems.
*** Age 12-13 is usually when most kids are ready for complete orthodontic treatment.
