He is usually a bit scared, as I'm sure most kids are. But, I try to make it seem like it's just not a big deal. I'm like, you aren't afraid of the nice dentist are you? You're too big for that.
I just try to make him seem like he can take it, and it wont be much bother to him. I want him to think he's overreacting. Then, when he gets there, it doesn't seem that bad after all.
The dentists are actually pretty good at making them feel comfortable when they're there. It's just getting them there that's the problem, haha!
