Older fillings and crowns have a life span. Stuff done in your early years will gradually need to be replaced. If you put it off too long, it will bite you in the *ass.

I'm no expert, but my wife is a retired dental assistant. Age alone won't cause cavities. The biggest issue is with aging gum tissue if not properly taken care of. My wife is a big proponent of the water pic for gum care and in between teeth cleaning.
