What’s Coming in When?

What’s Coming in When? A Tooth Eruption Guide.

While the arrival of your little one’s teeth might seem like a scattered and chaotic experience with very little in the way of predictable outcomes, there is a method to the madness! So, let’s find out which teeth come in when with this handy-dandy tooth eruption guide -- courtesy of the American Dental Association. With both the primary and permanent teeth eruption guides below, our journey through the mouth begins with our “front teeth” (the central incisors), and move backward from there. By the way, “eruption” is just a fancy way of talking about when your children’s teeth come in.
