I've had filling after filling and they chip and stain all the time. I was told I don't have much tooth structure left. My dentist fixed my fillings for me today and said yes I'll need crowns eventually. If I call my dentist to make an appointment to start getting crowns in the next month, can he tell me no, it's too early? I just figure I have to get them eventually and I'd rather start now than later and let my teeth get worse.
