I have a impacted wisdom teeth with a cavity and that infected the second molar. The doctor advised to extract both and put a implant for the second molar. I looking for ways to salvage it. Is RCT out of picture in my case? I have attached the X-ray for reference. I don't feel much pain. Implants will cost me in the range of $4k which I dont have with me now. Can you guys please look and see if it is really that bad?
