Growing up, there are many things we can usually rely on in life. We will most likely get taller, our bodies will get stronger, and our baby, or primary, teeth will fall out and be replaced by adult, or permanent, teeth. But sometimes, things don’t go according to plan. We may not get very tall or have muscles like The Rock, and sometimes we don’t get all our adult teeth like we should.
