Yes. My son went through the same thing. I called the dentist and they said that is very normal. (Her son even had that happen!) He finally lost the baby teeth after both of his bottom front adult teeth were in completely. As soon as he lost the baby teeth the adult teeth just moved forward into place just like the dentist office said they would. His teeth are now really straight. Lots of people told me that he would have to have them pulled, but the dentist didn't even ask to see him. And, he thought it was so cool looking like sharkboy.
