Tooth 47 hurts a lot for probing gums.

I have pain in tooth 46 which hurts for more than 2+ years now. Have pain for tapping, pressing and biting pressure on it. Cbct scans and xrays are clear since 2 years. But the Endo did root canal 2 years ago and no changes. Same symptoms and pain. Had partial retreatment last year(distal canal) and no changes. Had full tooth retreat with CaOH dressing in May'22 and no relief. Reopened again last week and placed CaOH again, because when they opened the tooth, it has some bubbles coming up while cleaning. Don't know if it means infected? They told me to extract 46 now as no relief with CaOH after 6 days now. Is it ok to ext 46? 47 started to hurt recently and Endo probes the gums. It was so painful for probing the gum on the buccal portion. He said no pockets seen. But gum is very tender and painful. Is that tooth 47 needs any treatment or extraction? Have had lots of treatments on 46. Is it ok to extract it now?or wait and see more if it heals ? Constant pain since 2 years now.
