You need confirm it with the x-ray whether it should be removed or it is capable of saving.... If the x-ray shows any fracture then extraction is the option... If there is only infection on periapical region, then you can do a re-rct and crown... Always after root canal, if you don't put a crown the tooth has a risk of fracture, so to save the tooth completely root canal plus crown is the complete treatment....
Next Steps
Start the treatment with prophylactic antibiotics, prescribed by your Dentist...
