I am 24 years old and have recently had a root canal on my #2 tooth, the last molar in front of my wisdom tooth
. Because of the amount of decay in the middle of the tooth
, the endodontist removed a lot of the middle and placed a temporary crown. In order for my dentist to place a permanent crown on my molar, he said a "core build up" is required, which jacks the price up to $650 total. Is this normal for permanent crowns?
