Molars come in at different stages of childhood, and the timing depends on whether they are baby teeth or permanent teeth. The first baby molars usually appear between about 13 and 19 months of age, while the second baby molars tend to come in later, often between 23 and 33 months. By around age 3, most children have a full set of baby teeth, including all molars.
The first permanent molars are often called “6-year molars” because they typically erupt around age 6, sometimes as early as 5 and as late as 7. These teeth come in behind the baby teeth and do not replace any existing tooth, which is why they can be easy to miss. The second permanent molars, sometimes known as “12-year molars,” usually erupt between ages 11 and 13.
It is normal for molars to come in a little earlier or later than average. Factors like genetics and overall growth can influence timing. Regular dental checkups help ensure molars are coming in properly and staying healthy. If there are concerns about delayed eruption, a dentist is the best professional to evaluate and guide next steps.
