"Mom, I think I swallowed my tooth." So says my six year old son.
"Why do you think that?"
"One's coming in way back here, and I don't remember one falling out."
Ah. So I had to explain that, as we grow and our mouths get bigger, we grow molars, or "big teeth" back there to fill the space.
Dmitri was relieved to hear he hadn't swallowed a tooth and missed out on a chance to collect a dollar from the tooth fairy. Until he connected more of the dots...
"Hey!" He pouted. "I get a tooth, but I don't lose one? The tooth fairy's ripping me off!"I didn't have the heart to tell him how the IRS works... :)
