less decayed than I would have thought

My back molar on the top left side comes out without much stuggle. As I examine it I see that it's in better condition than I thought it would be, which is sort of a relief because I was expecting all kinds of rampant decay.
I look at the empty space in the bathroom mirror. It doesn't look big enough to accomodate the new molar that will be growing in, and I wonder if I'll need some kind of orthodontic procedure. I wish I hadn't just declined dental coverage from work.
