Helloo.. first of all.. u have to confirm your tooth pain and get an x-ray to confirm its broken path.. so that whether root canal treatment is needed and after that new crown on the teeth is suggested.. If the broken part is more than two-thirds and severely broken then only it is suggested for extraction and need for replacement with new teeth..

Hello..tooth replacement can be done either by taking support of adjacent teeth or inserting implant in the extraction site depending on your clinical and radiographic examination.

There are multiple options  of teeth replacement  in a fixed manner ,subjected to clinical examination ,implant bridges etc

Your problem is not quite clear from the description that you have mentioned.... a clinical picture or x-ray of the tooth will help us to provide you with a better suggestion..... Regards
