I had no problem with my teeth until I went to the dentist for a cleaning. I was told I had a couple of cavities that needed repair. Funny, I don't eat sweets and had very few cavities during my entire life. After months of waiting, I got my appointment. I Had excruciating pain afterward. Never had any pain in my teeth at all. I can't chew due to the severe pain. Going back today to see if we can ease the pain. I think I will never again repair my "cavities". Get a second or third opinion before you let anyone repair a cavity that you never had before.
