Filling

[Mary thomas]

My dentist said I have a tiny chip in my filling. She tried to show it to me but for the life of me, I couldn't even see it. It's gonna cost about $100 to have it filled in amalgam. Do I really need to spend this money on the tiniest chip? I would rather wait and see it it gets bigger, then pay to have it done. Any advice would be appreciated.
