So, in fact, you DO have to have a filling, you've just declined to have it. And if you keep on that path, you'll probably end up needing a root canal (far higher cost, much more annoying procedure, far higher chance of eventual failure) as well.
I'm 30, and had never previously needed fillings, but was recently told by the dentist I needed a few. So I got them. Just because you didn't have much tooth decay until now doesn't mean you're immune; you really should get it treated.
