Leave it to grandma to be the booster of my confidence. Whenever I see the little lady, she will — without fail — compliment my smile. I, on the other hand, am quick to see fault with it, thanks to a discolored incisor that my dentist still can't quite figure out. But when it comes down to it, grandma is right. Slightly off-kilter tooth and all, my smile is genuinely warm and my chompers aren't so bad after all. What do you like most about your happy grin?
