How does my dentist prepare a crown for my tooth?
There are a few steps that go into assessing and trimming your tooth for a crown. If you have a deep cavity that reaches the pulp (where the nerve is), you'll need a root canal first. If not much of your original tooth is above the gum line, the dentist might build a foundation for the crown using a filler material.
Getting a crown usually involves two visits to the dentist if the tooth does not need a root canal, and much of the tooth structure remains above the gum line. At the first appointment, your dentist will likely trim down the tooth to make room for the crown to fit comfortably. Then, your dentist will begin taking the impression for the crown. The dentist will place a tray with impression material onto the trimmed tooth and then ask you to bite into the impression paste until the material sets. After the impression material dries, the dentist will remove the impression tray and send it to the dental laboratory. The dental laboratory will make the final crown. Your dentist will make a temporary crown to be placed on your tooth temporarily until your permanent crown returns from the dental laboratory.
At your second appointment, your dentist will remove the temporary crown and fit the permanent one, making sure it feels right before cementing it into place.
