Age-by-Age Dental Timeline for Parents"},"content":{"rendered":"\n

Most parents remember the first tooth \u2014 that tiny white speck poking through at around 6 months. But the second big milestone, losing those baby teeth, catches many families off guard. The average child starts losing baby teeth around age 6, but the normal range spans anywhere from 4 to 7 years old. If your kindergartener still has a full set of baby teeth while their classmates are flashing gap-toothed grins, that is completely normal.<\/p>\n\n\n\n

Understanding the timeline can save you unnecessary worry \u2014 and help you spot potential issues early. You can use the Age Calculator<\/a> to check exactly how old your child is in years and months, which matters because dental development follows age more closely than grade level.<\/p>\n\n\n\n

The Typical Baby Teeth Loss Timeline<\/h2>\n\n\n\n

Children have 20 baby teeth (primary teeth), and they generally fall out in the same order they came in. The American Dental Association (ADA) and American Academy of Pediatric Dentistry (AAPD) provide the following age ranges based on decades of clinical data:<\/p>\n\n\n\n

Lower central incisors<\/td>6\u20137 years<\/td>2<\/td>First to go \u2014 the classic bottom gap<\/td><\/tr>\n

By age 12 to 13, most children have lost all 20 baby teeth and have 28 permanent teeth (the four wisdom teeth come later, typically between 17 and 21).<\/p>\n\n\n\n

Girls vs. Boys: Who Loses Teeth First?<\/h2>\n\n\n\n

Research consistently shows that girls tend to lose baby teeth earlier than boys \u2014 by about 4 to 6 months on average. A 2019 study published in the Journal of Dental Research<\/em> analyzing over 10,000 children found that the mean age for losing the first tooth was 6.1 years for girls and 6.5 years for boys. This mirrors the broader pattern of earlier physical development in girls during childhood.<\/p>\n\n\n\n

When to Be Concerned<\/h2>\n\n\n\n

While there is wide variation in normal tooth loss timing, the AAPD recommends consulting a pediatric dentist if:<\/p>\n\n\n\n
