Agree with Claire. My DD didn't have any teeth until 13 months. She never seemed to have any trouble chewing or swallowing foods. Of course, I didn't give her raw veggies, but pretty much everything else was fair game. I was told by my Ped and her dentist that getting teeth is the most variable (and least important) of all infant milestones, and in fact, there is some school of thought that suggests that the later they get teeth, the more healthy and strong those teeth tend to be (not sure I buy that).
