It's pertinent that you have to replace a missing teeth except the third molars within a short period say within 2 weeks. You may get a fixed denture done.

Broadly speaking you have three options to replace missing tooth/teeth, first is a removable partial denture, second a fixed partial denture and lastly an implant based prosthesis. Procedures for the above do not cause much pain however you may have to take local anesthesia once. Please go ahead and discuss all options with your doctor. All the best.
