I have broken/bad teeth. Can they be fixed without anesthesia?

Do u have to have general anesthesia for dental implants, not local anesthesia? I can't be put out, had a bad experience & is not recommended for me. I'd rather be awake, is that possible? Front 6 are broken, a couple at the gum line, two front ones not at the gum line, but are very small. I have a bad tooth in the back molar, probably needs a root canal. All bottom front teeth are perfect and good. A couple in the mid (not front or back) broken at gum line. Would bridges or crowns be an option?
