Need a shot on your tooth to get a crown?

Only if vital: If your tooth has been root canal treated, being numb is elective--but remember, the non-feeling tooth is still attached to very sensitive gums and bone. If the tooth is vital (normal sensibility) you should be numb for comfort ( yours), so your dentist may prepare your tooth for the crown. If not, you are likely to jump/move and disrupt the dentist's work. Fyi: painful dentistry is a choice.

Not good: Not good for either you or the dentist for you to have surgery done without an anesthetic. Your treatment will be smoother, easier, more productive, if you are comfortable.

Local Anesthesia?: Most patients require local anesthesia for these types of procedures in order for them to be completely comfortable and for the dentist to be able to accomplish this task proficiently without stress. Even if the tooth had rct, i often numb the patient as getting a perfect impression is essential and sometimes involves slight discomfort. Some patients are fine w\o an injection or ok with sweet air.

Definitely, yes: Before the process of prepping your dental crown, your dentist will need to anesthetize both your tooth and the gum tissue around.
