I was at the dentist this week due to toothache in the back molar area. It has been filled before but she thinks it will need to be taken out and a deeper filling or root canal needed. I have an appt this week and she said it will take 2 hrs as they have to put on full PPE and I will only be able to get a temporary filling due to restrictions. I understand that drilling would be risky but don’t understand why putting in a temporary filling would be any safer than a normal one as they will have to drill old filling out.
