This picture book captures a child's rich imagination through the simple event of losing a baby tooth as a permanent one grows in. The bold, spacious illustrations of the characters perfectly match the lively storyline. One morning while eating breakfast, a tooth falls out! It had been loose for a few days. Something that had been deeply rooted in the child's body suddenly comes free, leaving an empty space behind. For the child, this is a brand-new experience—it feels scary, strange, and even brings a sense of loss. The child blows air through the gap to make funny sounds, and imagines making a set of dentures out of an acorn or a coin to fill the empty spot. Mom and dad share fun facts and traditions about teeth. "This was the very first tooth you got," Dad said. Looking back, it seemed familiar from photos too. "The first to come in is the first to go." "That's proof it was a baby tooth," Dad explained. Oh! So the teeth we get as babies are called baby teeth! "An adult tooth will grow in its place. But once that adult tooth is gone, it won't grow back. That's why we call it a permanent tooth." "Perma-what?" "No, no," Dad said seriously. "A permanent tooth never grows back, so you must take really good care of it. Otherwise you'll get cavities, and if the cavities get bad enough, you'll end up needing dentures just like Grandpa." —Excerpt from the book
