Why do our teeth only grow back once after we Iose our baby teeth?


Your first set of teeth grows in when you are approximately 6 months old. These baby teeth, or deciduous teeth, grow in at a size that fits your jawbone at the time.

As you get older, most parts of your body-including your jawbone--continue to grow. But your teeth stay the same size. Eventually, your baby teeth become too small for your larger jaw.

Between 6 and 12 years of age, you grow a new set of teeth that pushes out your baby teeth. These larger adult teeth are a perfect fit for your bigger jawbone. As a result, there's no need to go through another round of losing teeth.
