I had a same day permanent crown placed about 5 days ago. The crown does not go all the way to the gum line and I can actually place my fingernail in the space between the crown and the tooth. Is this normal? This is my first crown. Also the dentist placed the crown on the wrong tooth. We discussed at an earlier appt that 2 teeth next to each other that needed crowns. It was decided the one further back could wait and do the other one first. When I got home I noticed he did the further one back. Don't know how to mention that the wrong tooth was also done.
