Hello
Your tooth definitely needs a re root canal treatment for sure.
Its always suggestive to try a re rct once before getting a extraction done for the tooth.
Re rct charges varies from place to place and from skills to skills.
I will advise to get it done from a good endodontist only who is the person specialising in only root canal treatments.
We are available for video consultations just in case you want to discuss more about your problem.
