6 to 12 Months

Most babies will get their first tooth between 6 and 12 months of age. If your little one starts later than this, don't worry! Every child develops at their own page. However, the American Academy of Pediatrics suggest parents talk to their pediatric dentist if their child doesn’t have any teeth at 18 months. The bottom front teeth are usually the first to come in.

8 to 33 Months

The bottom front teeth are most commonly followed by the upper front teeth. Baby teeth tend to erupt in pairs and usually the bottom teeth will come in first followed by upper teeth. Between 24 and 33 months of age, the top second molars will finally erupt and your child will have a full set baby teeth- 20 of them!

1 Year

According to the American Academy of Pediatric Dentistry guidelines, children should have their first visit to the pediatric dentist no later than their first birthday- or when their first tooth comes in!

6 to 7 Years

As with baby tooth eruption, there is a wide range of variability when a child’s baby teeth begin falling out. Generally, most kids lose their first baby tooth between six and seven years old. Teeth usually fall out in the same order they came in- usually the bottom first and then the top.

7 to 12 Years

The remainder of the primary teeth will generally fall out between the ages of 7 and 12. The very last baby teeth to fall out will usually be the second molars. Remember, every child’s development is different and there is a very wide range of “normal.”

Please keep in mind that this is JUST a guide! There is a wide range of variability when the first tooth may appear, so please don’t worry if your child doesn’t follow the chart.

A few takeaways:

  • Every child develops at their own pace- it is normal to see teeth early and also normal to see them late!
  • Did you know babies are born with all their primary teeth below the gumline waiting to make their debut?
  • Most babies will develop teeth between 6 and 12 months.
  • At around 3 months of age, your baby may have increased saliva and may frequently put their hands in their mouth. This does not necessarily mean your baby is teething.
  • Lower teeth usually erupt before upper teeth, and teeth usually erupt in pairs!
