I've had this permanent onlay for 3 years in a molar, and it just popped out when I was flossing. I have good dental health, but had orthodontics on and off in the mean time [there was a metal ring around that molar]. Could this have weakened the onlay?
How should I approach my dentist? I am mad that their work didn't last, and wonder if their repair will. I'm also wondering if they give a price break on the repair vs. going to a new dentist for the repair.
How long can I leave my tooth in this state without risk to it, as it's exposed, but not causing me severe pain; just sensitive to heat/cold.
