Help!

Three kids.
One mom.
One dental hygienist.

I think it might equal disaster.

Beth and Anna say they are going to be good and open their mouths for the lady, but Beth said that last time too and she most definitely did NOT open her mouth. This time I bribed them, said I would buy them a treat if they cooperated. What does Anna want as a treat for being at the dentist? Smarties, well actually she said she wanted Farties, but I know what she means. I wonder if they'll brag to the hygienist that mum is going to buy them sugar in a box when we leave?
