0hhhhh ... how could I forget the plaque dye? I'll see if I can find some - that may be a very good solution, since he is standing in there brushing, just not effectively.

polarbear, I had to laugh at the clothes thing. I think he's exactly like that with his teeth, and while I'm sure that will change when he starts liking girls, by then he may have a mouthful of cavities or worse.

So I'll try the dye and see if that does the trick. Thanks so much for the advice.
