Q. I have recently had a filling four hours after the filling ,.. it fell out,.. it was a small filling ,there is no pain yet and i can see the flling was very shallow,.. it is in the back of my mouth . i dont want to go back to dentist because ive taken too much time off work,. would there be a problem if i gave it a week and if no pain, just carried on brushing till my appointment in 4 months
