Q. I had my Vaneers done 3 years ago. now the front one has dropped off i have been to the dentist who has replaced it only yesterday. it was way too big and my dentist drilled and sanded it why it was stuck in my mouth when i left the siugery after paying i was unhappy with the results but 6 hours later it dropped off anyway is this normal?. would you recomend me to have a crown replacement instead of vaneer?.,
