I have a pretty large cavity in the tooth to the left if my upper front tooth. The tooth feels wiggly, will a crown fix this? I have an appointment with the dentist next week. What can be done about this? Will the tooth be able to be saved? Is this a dental emergency our should I wait until next week? Petrified to go to the dentist but really don't want to loose the tooth.

Most teeth can be saved, not a crown but other work

If they do have to pull it ( most likely they can save it) there are implants they do now, and no one will ever know the difference.
