This morning my dentist prepared a back tooth for a crown. She said she would place a temporary crown on but I don't remember her doing so. The tooth doesn't look to have a crown on at all - black part like what an amalgam filling looks, and feels soft and funny but anaesthetic is only just wearing off. Am I worrying about nothing or could the dentist have possibly forgotten to put the temporary crown on? I'm due to see her again in 10 days for the permanent crown fitting.
