Both times I've stayed away from dentists for long periods, it's taken fractured molars to get me back there. So let's hope your office is good about following up on followups!

(OTOH, I'm not convinced they wouldn't have fractured even if I'd gotten them cleaned regularly. I still suspect the jerk who put in all those fillings back during my last year of college did most of them unnecessarily and all of them badly. Both of the bicuspids he filled eventually needed root canals. On one visit, he was actually lecturing his assistant about how to hand him the implements correctly while I sat there with the Novocaine wearing off waiting for him to work on my mouth.)
