I had assumed that prosecution/defense would've asked. But, then again, BvD didn't know her kids' dentist's name.
Someone else mentioned that 7 yr olds have teeth being replaced all the time. Who would know if she didn't have a loose tooth already & any slight bit of "trauma" would've dislodged it without blaming it on suffocation? Would the parents admit that she had a loose baby tooth? Or would that just help the defense? "Oh no, no trauma, her teeth were going to fall out in a week or so anyway."
