Dental Development from Birth to Early Adulthood

Healthy Smiles Start Early

Bippo’s Place for Smiles encourages parents to follow AAPD-aligned recommendations—early dental visits, proper brushing habits, and routine checkups—to help ensure strong, healthy teeth from childhood into adulthood.  Understanding how children’s teeth grow helps families support healthy smiles from the very beginning.  Dental development follows a predictable path:

Birth to 6 Years

Even though you can’t see teeth yet, babies are already developing them below the gums.  Enamel, dentin, and the basic tooth structure continue forming during this stage.  Parents can help support healthy development by gently cleaning the gums with a soft cloth.  Most babies get their first tooth—usually a lower front tooth—around 6 months.  By their first birthday, several incisors may be visible.  Schedule your child’s first dental visit before they turn one.  By age 3, children typically have a complete set of 20 primary teeth.  These teeth are essential for learning to chew, speak, and smile confidently.  Regular brushing with a small smear of fluoride toothpaste becomes especially important.  While baby teeth are still in place, the permanent teeth are developing underneath.  Parents may notice spacing between baby teeth—this is normal and provides room for adult teeth.

6 to 12 Years

This is the most active stage of tooth transition.  Children begin losing baby teeth around age 6, starting with the lower front teeth, and adult molars erupt behind the baby teeth.  Regular dental checkups help monitor alignment, cavity risk, and jaw growth.  We typically refer 8–10 year-old patients to orthodontics for thorough assessments during this important time in dental development.

12 to 18 Years

Most permanent teeth—including canines and premolars—are in place by age 12-13.  Wisdom teeth may emerge between 17 and 21, though many teens may need evaluation for removal.  Consistent dental care during these years helps protect the nearly complete adult smile.
