I was wondering about how long should I give gizmo to loose the baby teeth that he still has. He is eight months old now, and the adult teeth are all coming in. Most of the baby teeth have already fallen out on there own. But the four top teeth in the front are still there. They really are not even loose let. The adult teeth are in behind them, and have pushed them forward and out a little. I need to know if I should give him more time, or take him in now??
