Usually. When getting fitted for a crown, remember the tooth is usually alive. If a tooth has has a root canal, we still handle the tender gum tissue that surrounds the tooth. Local anesthetic, gently administered, will assure you of a painless, comfortable and worry free visit.
Typically. You should receive an injection unless the tooth has had a root canal completed on it. With a root canal, it iis optional, depending on if you want the gum tissue numbed around the tooth or not.
Most of the time yes. When starting a crown it is rare that you would not need an injection at some point. If it is a traditional crown you will come back for it to be placed and then you are less likely to need an injection especially if it has had a root canal.
